Title: Rodney Williford Offers A CNC Machined Head w/springs
Post by: Ghost-Geezer on February 07, 2015, 09:45:56 PM
Recognizing that this is primarily a Turbo site, has anyone used Rodney's headwork/springs on a N/A Gen II for the street?

If so, please provide input.  Thanks

Dave

If I had the $ that's the route I'd go bro,I've heard a good ported head and some cams really wake these Gen II motors up. :thumb:

I'd definitely have the ECU reflashed ASAP with the usual mods(pair valve,top speed restriction turned off,raise rev limit 500 rpms,etc.)and maybe pick up a quick turn throttle from Schnitz(I did and like it over stock).If I were you bro I'd ride it a bit with just the pipe,ECU reflashed,etc. and if you need more zip go with the cams and ported head.If you're gonna stay with swb that's a solid 200+ hp and a big enough handful in the first couple of gears for general street riding(nothing like your old turbo bike but that was more useable in the upper gears with a stretched wheelbase).

From what I know of his work Rodney is a great tuner and engine man, about any work he does is first rate, I would just to remind you before investing a ton of money in traditional Eng mods that you may want to consider a stage 1 turbo, I'm not talking anything like your other bikes, but a mild stage 1 would give much more than modifying the Eng with old school methods, not knowing exactly what your after in the way of power, but I have done this myself more that once so I do know what I'm talking about, when you port the head and upgrade the valve springs you give the motor a bit more upper mid range and higher rpm HP, however your off idle and low rpm power MAY suffer a little, now more compression would make this back up and then some, also a good set of cams would really enhance this setup and for sure there is very few that better than Rodney on a dyno, I do know if you go this route you may be disappointed with the power results from just the head work, as I got a feeling your  a bit like me after you cranked on a turbo about anything else is kind of a letdown, now if you went with a whole package, headwork, bump up compression, cams, springs, adjustable cam sprockets, and a dyno tune, you would like end up with maybe 225-230 HP or maybe a bit more??? and it would be a kick ass motor, but after paying for all this work to be done, I sure you would have a ton more invested than with a stage1 turbo kit, now please keep in mind I'm not going off anything I have read or heard about in this forum or anywhere else, this is shit I have done myself, doing my own work, including most of the machine work, with both cars and bikes. and lastly no matter what direction you go, don't get screwed up and go missing again  :lol:

How about a Gen I cylinder punched to 1440 with all that other stuff you mentioned?  Is 1397 more practical?

What about heat on the street with that set-up for pump gas. 

Will it be difficult to start hot?  (Will have a lithium battery with more cold cranking amps)

Will the valve adjustment intervals be significantly shortened?

Top end motor noise, particularly at idle running Alysyn less than zero weight oil?

Thanks in advance!  :bike:

Lots of 1397 and 1441 motors running around with a Williford head. I would say most are street / strip applications.

Lots of race bikes with them as well, turbo, nitrous, and N/A.

Nothing is going to feel like a turbo bike of course.  That said, have you even ridden the new bike yet? Who knows, you might like it box stock :-)

These Gen 2 bikes are a lot better than the original Gen 1 for ridability .  .  .

No, I have yet to ride it, (shop is still waiting for some parts - they are doin' my grunt work) but with my having had 3 iterations of turbos on my 2001 - which ended up at 523 RWHP (virtually unridable on Hi-boost) and Dennis' old bike at 440 RWHP I know in my gut that I want more than 190-195 out of my N/A bike.  My magic number, i.e. my wish list for this new bike is a firm 220 with 125 ft lbs.  I am seeking a very stout/flat torque curve above 7K and more than 200 at 7500-8000 all the way to 10,500. 

Is that achievable with stock cams with adjustable sprockets? (I am afraid of bigger cams on the street) and Rodney's CNC porthed head with 1397 CCs pumping underneath?

If I can get that from my N/A bike and retain 90% "stock" reliability"............I will be like a pig in good slop!


BTW, I spoke with Rodney's spouse this morning and he is at the track testing and tuning on this fine 67 degree day, but she said he will call me this evening.

OK if your really dead set on going NA instead of turbo, I would go with 1441 as you would have the crank already, also I believe bore size of 1397 and 1441 are the same, and as long as you just used a good street/strip valve spring and the head was set up by a pro, it don't seem as though your valve adjustment intervals should much different than stock, I'v seen Busa's with 50K or more and never had the cam cover off, of course as I said the main key to all this is quality parts and a pro builder, as my time as a dyno operator is rather limited compared to some, the motor your talking about, gen2 1441, cams, head work, put together and tuned by Rodney or someone comparable, (Steve Knecum) should get you into the 240-250HP range, (about where a stage1 turbo would be with 5 or 6 psi boost on a stock eng) but you may need two batterys to start it when hot, and it would probably need race gas, you would need to ask Rodney about this, ......one last thing is you could just put the pipe on and PC get it dyno mapped and take what  it gives you..........I know that would go against the gearhead DNA we all have  :lol:
Title: Re: Rodney Williford Offers A CNC Machined Head w/springs
Post by: Ghost-Geezer on February 08, 2015, 02:20:29 PM
Yes, Rocket, I am going N/A all the way.  I do not wanna run race gas.  I do like the idea of a 1441.  I love the idea of no additional heat.  The lithium battery we are using has around 80 more cold cranking amps than a stocker.  You are making me sweat little motorcycles and my brain is on fire.

Thank you for that.  :D

Also, even though the BST carbons will not reflect on the Dyno, I am hoping the reduction in unsprung weight and rolling mass, particularly at the rim, will make the bike think it has more power than the Dyno sheet says on the street, particcularly in 3rd and 4th gear roll-ons.  Whadaythink?

You are correct about the DNA thing..........I wanna build it to 1441, more HP/Torque....stock-like reliability and ridability.

Not sure if you can get what you want with stock cams..

How many miles do you ride a year?

Does Tommy Grimes still have the "old" turbo bike?
Title: Re: Rodney Williford Offers A CNC Machined Head w/springs
Post by: Ghost-Geezer on February 08, 2015, 06:37:45 PM
I ride about 4-5K a year.  I would be willing to go with larger cams as long as valve adjustment intevals were "reasonable" and this afternoon I received a couple of PMs that told me "not to worry" about that issue.  The member was speaking from personal experince on his own 1441 GEN II.

Yes, Tommy still has my old bike from what I know......have not seen him in a while.  Here is what he did to it.

He apparently did not lube the chain very much, if at all, he just would jump on it, ride it and park it.  :bah:

Dunno if he ever fixed it or just parted out the carcass.  He likely parted it out.

Post by: Ghost-Geezer on February 09, 2015, 11:21:13 AM
We have a Winner, folks!!!!

Rodney and I have come to an accord and here is the list:

Dyno pulls before and after kit installation including complete tuning of 1441 motor on Dyno for pump gas.
Gen I cylinder bored and plated
Brock's clutch mod
Raise rev limiter 500 RPM's but retain stock 186MPH cutout in sixth
Reuse Ti-valves with stronger springs for cams - cam profile to be as linear as is possible
Web cams with adjustable sprockets
1441 piston kit
My cylinder head CNC ported

Target is 220-225 RWHP on pump with 125 ft. lbs

That concludes the list.


The bike below - I built it in 1984 and in Sept of 1985 "Hot Bike" ran it on the cover - my 15 minutes of fame, I guess.
It was later featured in EasyRiders as well.

We built that kind of motor for my friends gen2, 1441cc, biggest cams that stock valve train accepts, and if i remember right, we left the stock springs in. Otherwise max for titanium valves would be 43lbs when don`t want excessive wear in street bike. He drove it quite a lot without any issues, 3tmls went in couple weeks touring. He wanted to hit the 200mph also, so limiters were off, result 208 on a mile.

Wont it still say 6th if you remove the 186 limiter with ECU Editor vs using a TRE???

In all honesty, you have me at a disadvantage.  I do not know.  But if that is the case, we will bypass the limiter.  I will let Rodney make the call.

The dang rims are 4 weeks out in production and shipping...............it will be a while.

I made a "Command Decision" this morning in moment of epiphany.  When all is done and Rodney calls me to come get this bike, I am going to see if he would be willing to keep it a bit longer and take it to the track and make a couple of passes.
I would really like to have that slip and post it up for you gentlemen.  That would be more fun than a barrel of full of 10 dollar bills.

Whadayathink?????  :bike:

That is no longer and issue with an ECU flash/tune.  The bike will be unrestricted and the gear position sensor will work like normal.  It's all up to your hand and gearing if you run 200+.  I'd just make sure the bike is unrestricted if you want the most out of it regardless if you plan to run 6th to redline.. ;)

Post by: Ghost-Geezer on February 11, 2015, 07:14:00 AM
The Web adjustable cams he will be using will provide a linear/flat torque/HP curve.......giving a broad range of power/torque in exchange for a few peak HP.  Spring pressure will be moderately more but not astronomic.

That is why I asked for 220-225 instead of 235+.

Valves should be just fine.

Since I will not be racing this bike, what can I expect for engine life on a fresh 1441 build? 

Any thoughts?

Would 2" in the swingarm be woirthwhile?

Would it kill the handling in the mountains?

Or would the bike not care?

Thanks

OK I guess on the springs, its just I'v heard horror stories about the Ti valve with heavy springs.....and the 2in arm is a great idea, the bike will be easyer to keep the front end down, and at  our age we should not pushing curves hard enough to ever see the difference of a 2in arm

Kind of hard to say for sure, but if Rodneys as good as his reputation, I cant see any trouble, of course all bets would be off if you were running LSR, or at the drags every week, but street ridden, don't see a problem, I would tend to change the oil a little more often than in a stocker, and to me anyways it don't matter if its synthetic or not, as long as its a good brand name oil,........I just remembered you mentioned Brocks and using that 0-30 oil, I would not do this, that oil is like piss when hot, I know Brock swears by it, but builders that experiment with other peoples stuff will say that, I have read Brocks articals, and I agree that he can make his bikes haul ass, but that oil is used for getting that last HP or two and not for much else, personaly use a good brand 15-40 diesel oil, change it and filter every 1000-1200 longer if it stays clean, sooner if it shits up
Title: Re: Rodney Williford Offers A CNC Machined Head w/springs
Post by: Ghost-Geezer on February 11, 2015, 08:27:05 PM
Yeah, I know not to use that less than zero oil in a built motor............will use what Rodney suggests. which is Motul 300V 10W40 Full synthetic..   1,000-1,200 miles 'twixt changes, on the surface, seems short, but this ain't gonna be no stock top end.  I can do that.  Oil and filters are relatively cheap.........1441's are not.

Thanks

P.S. This Board is a shadow of what it was in terms of activity.  How can we liven it up a tad?

I know you guys want me to go turbo again -  My apologies, age has taken is' toll on ole

That's a lot of work just have a piece of paper that sez I went 200 MPH.  Shoot, I did that on the street with Dennis' bike, according to the GPS - a solid 204.

I will leave the LSR stuff to you youthful friends..........I can play a bit on the hi-way and the back road 2 lane swoopys and get my blood pumping again.  I think I would be afraid to go that fast again.  That kinda thing happens sometimes when you are approaching 70.  :)

Why leave it stock just because Dave doesn't want to do LSR and go 200+ MPH?  A big hp Busa with stock wheelbase is an absolute hoot to ride on the streets. I think it is a great build with top notch components. Good for you Dave. Enjoy.

Rodney has not returned my calls or E-mail.  I know he is busy.  I guess my money is not good there.  I was at least expecting the courtesy of a return contact..........I really would like to run his CNC ported head, even if it is on a stocker.   That would help some.  He is just too busy. 


That was very unfair of me to say.

What time are you calling? if you are calling during the day it maybe hard to reach him. 7 pm is generally good and on the weekends is good also. Earlier hrs are good on sat. I had no issues contacting Rodney.

I just heard from him.........he has been in Europe with his wife and 6 kids.  Just got back.  That is a lotta kids and his family (of course) takes first priority in his life, as it should.  We will work somethin' out, I am sure.  Lots of time left before ridin' season.

Rodney was gracious enough to just spend an hour on the phone with me.  We ironed out all the details for my new sled.  It will have a 2"-4" alloy arm.

Head and cam kit only for now.  Cams will be tuned for broad, linear torque band. Head will be shaved .012-.015.  Deck height will be set. All clearances

will be checked and double checked.   Complete Dyno tuning/mapping. Bike will be dynoed before and after.  Rev-limiter to 11,500....no top end limiter. 

Hope to pick up 20. That is a ton, and I will take it.  205 is the target. Alloy arm saves 5 more lbs.  Bike should weigh about 520 curb weight.  Rodney

agreed to take it to the track and get me a slip or two. He weighs 160.   With him on the bike = about 690 with gear.   I predict a very high 6 in the

1/8th, and a high 8 in the 1/4.



Sorry if I sound like I am braggin', I ain't............I am just dreamin' and havin' fun planning all this stuff.  Payin' for it is another issue entirely.  :eek:

 :tu: It would appear so.  That new alloy arm costs about a grand.  I chose that over the chrome-moly.  I have seen chrome-moly crack in years past.

Very high 6 in the 1/8th a typo? I'd expect him to go alot quicker than that.

Well, in the course of our conversation, I thought he said he could get me into the 6's.  I just assumed high.  I was likely wrong.  Could be low 6's.

However, 8's was 1/4 target.  Arm will be set at 4". 

He may go without a base gasket and just use copper-cote while removing .015 from the head.  As long as clearances up top are within spec.

I heard all those guys run that Rotella. .lol.     1441 ridden as an actual street bike with 425 cams will eat tappets within 1500 miles.   If you want a maintenance free 1441 just put yosh stg 2 cams in shim the spring and never ever have a problem.    Ported heads alot of times with big cams lose bottom end.    I've done tests with 1441 and mild cams vs ported head with big cams and guess what??    Milder set up made 20 ft lbs and 20 more hp in the middle with the ported  head made 6  hp more up top at 10500,  same combo with a stock head no port work only made 7 hp less.   Combo 1 220 same combo no port work 214.  Just something to think about!!    It's all based on what your doing with the bike.

What you say makes perfect sense.  Cams will be relatively mild..............spring seat pressure around 20 lbs more than stock. Looking for a broad torque band - all street riding.

My arm is 2 over. It gives me a fighting chance against wheelies. Usually spins before it comes up. Once the tire is hot it comes up no matter what though.

That sounds more like it, with Rodney on it, with Dave, myself, Jeff, or any of the rest of us old farts, still going to be high 6s  :lol:

Maybe 7's in the 8th for me.  Maybe, if I am lucky. And do not fall down.

What do ya weigh?  I weigh 156-158 (No Gear- add 9 lbs) )since I went on the Atkins Just Water, Coffee, and Cigarettes Diet.  Bike will be realistically 530, perhaps a few less, certainly no more.  That is 167+530 = 697.   That's is still light in my mind.

Nice shoulders, remarkable face, floppy pectorals, tatoos on arms, barrel chest and gut, hair everywhere except on the top of my head, unshaved groin, hairy legs of unequal length.  I look like the leaning tower of Pizza in bare feet.  With my cane, I do better.  Got built up shoe for lame leg.  Size 13 1/2 feet with yellow toenails.  That's about it.


Think about that picture.

I came away from Viet-Nam with fucked-up toes.  The one big toe is half gone and all of the others are carrying yellow toenails.  Dunno, it must have been jungle rot.
