I need to work on this.
He says 3500 then let the clutch out and don't let the rpm come up. hmmm
country roads here i come.

Hey Jeremyg 1283. with your gearing you need higher RPM. since I last saw you run your first pass at 6.88. Jeff is right weight is so important, You can launch a lot harder and slip the clutch more. I run a 16 / 47 and launch at 6500 or higher with my big old self on it and got a best of 6.52 sec. at 119 mph..my 60' is 1.62.. I need work on that. In about 3 weeks I'll be back out.....I have Adam's cell since he moved.

Yes. But. A 14R is 1441cc and your Gen1 is 1298. 14R w bolt-ons is making 200rwhp,your Gen1 is 160-170rwhp at best. 14R also has a shitload more torque then a stock Gen1.
Different horsepower/tq/powerband requires different launch strategies. Try 3500rpm,most likely the bike will stumble and you'll kill your ET.
From what I can recall,when my Gen1 was SWB and engine was stock I'd leave around 5500-6500rpm. Now,when my Gen2 was stock,if I left at that rpm I'd get a decent 60' but a shitty 330' cause it would wheelie hard. I adjusted the rpms lower and found that 4500rpm was good for me.
Trial and error. Everyone has different riding styles. Experiment with different rpm and make a mental note of which works best. Then strive to replicate that over&over until you are consistent. Just go slow and take your time. Trying out too many suggestions and following several peoples advice may overwhelm you.
Practice practice practice....if it were easy everyone would launch a bike like Rickey or Teasley :tu:

Doug ~ did Adam get a new cell phone number ?
With 16/47 you can toss the lever & pin it !
The Z X 14 makes way more torque .
Weight makes HUGE differences.
Heavy guys need low gears.
The lighter guys here.
Not so much !

Red,that 14R you posted is based out of Cali correct? I swear I read an article(either online or in the now defunct SSB magazine)about that bike and the owner/his son in regards to E.T. advantages of using a multi-stage clutch. For some reason the name Augie is popping into my head

Good points do you remember what kind of ET ran with your stock busa.
It does apply though how he spoke about the clutch and opening first and not letting our Rpm go up then come out of the hole.

Back in 2003 on my first Busa which was a '99, I ran a 9.59 @ 146.27 mph. It had an early small tube Hindle pipe, BMC filter, PC, -1 front, lowered and strapped. Stock wheelbase and foot shifted.

Thats kickass! Man i hope to can get my bike to do something close to that. In the 9s stock would be awesome stock.

They only made about 158RWHP stock......................new stockers make a bit more.

...and that would be on a good day with a happy dyno(for a totally stock Gen I with factory exhaust,etc.).Most seemed to make around 150-151 at the rear wheel,and 161-162 with a good exhaust,PC,etc.

Launching a swb Gen I would be totally different than launching a Gen I with a 6" over arm.Lowered,strapped,and 6" over you can gear it down and get after it pretty hard,whereas I've seen swb Gen II'S actually drop a tooth on the rear and leave fairly soft to avoid a wheelie.I've never been able to pin mine in 1st gear without the front end coming right up so have to gradually roll it on(which is a pain in the ass),on my Gen I I could hammer it in 1st and never had the front pop up.I believe the main thing is to try to be at WOT/clutch all the way out at the 60' mark.I remember when little(about a 135 lbs. :lol:)Richard Gadson ran an 8.99 on Brocks Gen II,had to drop down to a 42T rear:

Once my bike is all tuned up with nitrous and motor work its gonna be a different story. Lol
It will be a fun time at the track this year. Hope to learn allot and be part of it.

I could only imagine launching oldgixxers gen 1 or gen 2. Lol

Yup,I run 18/42 on my SWB Gen2 and sometimes 18/41 for 1/4mi duty. Go through the traps at the top of 4th gear.
Jeremey,it's been a long time since I ran my Gen1 with a stock engine & SWB so I looked through some of my timeslips and 9.70s-9.80s at 140-143mph were the best I could find. Sounds about right;since I was 235lbs back then.
The bike was lowered,small box mod,Yosh RS3 pipe,PC2(anyone else remember those? lol)and had a welded slipper.

Ok cool. So a 9 sec pass stock is what im shooting for then. Hopefully my suit fits i ordered. If so i will be running on the 7th. Coming out at 5500 like you guys said. 9.70 is fast as shit.

Had you dynoed it? HP? My stock 06 dynoed at 160.something, not quite 161, I forget exactly. With modified stock cans, just opened up a bit, it actually lost 5 HP. They sound better though. :D. Had my CBXs dynoed that day too, at San Jose BMW. BTW, in your pic, the front doesn't look tied down, was it? I know the wheel's up but there's a lot of air between the fender and fairing. Was your 9.81 pass tied down or lowered?

Jeremyg...I try to have clutch out and pinned at the tree. ,But mines 9 over lowered ,but stock motored. you need lower gears. Like Red says practice ,practice. if your going to Fontana , I will try to make it there on the 6th and 7th.

Doug yours is 9 inches pover ? You hav pics of this? What do you mean by geared

Yup,
Seat time will make you feel more comfortable with what you'll need to do . . .
When I was a poor drag bike racer ~ I could barely afford a new tire !
So to leave on the back wheel was how I made it hook up.
Click on that link above to see some good photos.
You'll get better with practice at the strip !
In E/T reaction time WINS races .
You don't need to be fast ?

I don't want to be motorcycle racer for a living I just want to have fun dragracing and get the best time I can possibly get. That's cool that you figured out leaving just on your rear tire got you a better ETA I guess seat time is the best teacher
-
I told a friend to bring the motor to4000rpm and throw the clutch. Stretched, strapped, and lowered. She immediately picked up a second. Best 60 foot was 1.61 I think.

So different on my bike.
On my Gen I Busa, stock except for stock modded header 4-2-1 into free flowing mid pipe and modded stock canister. 17/46, stock air filter w/small box mod, ECU editor.
9.70s @ 140mph w/1.50 60ft, 6.30 1/8th launching off idle and a 175lb suited rider at 5300ft. altitude
With me at 280lbs suited I had to launch at 5500 and try to hold it from dropping very little. I can only run 10.30s.

So same bike you lost a 1/2 becuase you weight 280. Was the racer exp?
I weight 185 suited so I have a chance of a 9 sec run.

The bike will be capable of a mid 9sec pass once you have the arm on it. Even if you launch off idle,and can lock the throttle wide open in 1st gear and nail the shift to second,it's gonna be difficult to not make a 9sec pass.

Jeremy, I have a 16/47 combo,4 inch lowered front,3 inch lowered back, and it might be 10" over. I'm doing nothing but chassis work to max the bike out before throwing horse power at it. I'm 245 suited also. My weight hurts my 60' and everything else down the track. You'll see it at Fontana. I'm going to Irwindale Thurs. for one last test on another clutch set up. See ya at Fontana !

Both of us experienced but he is more experienced with more time in the seat of his bikes and mine. Being over 100lbs heavier makes a huge difference not only in math but how the bike needs to be configured for different weight riders as well. I wheelie easier by 10 fold than my friend so a 6" extension would help me narrow the gap. It doesn't really help him as much because he doesn't "Romp" on it as hard as some of the pros. His style is better suited for SWB.
In April I am putting my stock engine back in and will have run it again as I did a few tweaks here and there.....shooting for 9.50
-
Busashot this is awesome info man. thanks for sharing yoyr exp../
I want to get my arm on and see how it runs
first order of business is seb runs to see where the hell this bike and my driving stand. I would imagine it will be low 10s to start. I have been woeking on my launching but need to watch skilled people so I can learn what I need to do and NOT do..lol
-
Sure thing. There are way more experienced Busa racers here on the .org. Most of my experience on Busas is all around skills. Road racing being one and back in early 2000s the top speed bug.
IMHO, depending on how someone launches can dictate how much stretch is needed or is warranted. My friend's technique works the same on SWB as well as 8" out on his 2012 ZX14R. In fact his best ET and MPH was at SWB.
Never road the Busa stretched so my only experienced on a stretched and lowered bike is my old 85 Kawi 750 Turbo w/6" stretch. Certainly helps with wheelies but I have had that one lucky hard launch with 100% grip then seeing nearly 12 o'clock with it. Strange feeling and painful when your chin slams the tank and then upon touchdown my cahones getting a nice kick in em........fun times indeed.
Have fun!

The tech guy for NHRA works both irwindale 8th mile on thurs. and Fontana's 1/4 mileon sat. and sun.A 6.40 e.t. and you have to get the NHRA license at irwindale.135 mph at Fontana and you have to get the license. I ran a 6.41 on thurs.on the 8th, and then at fontana ran 134.52mph. he asked if I was doing this on purpose! So close at both tracks.
