I've been meaning to post this here for quite some time.  This is my toy I built a few years ago and have fun swearing at.  Thought you guys might be interested.

DRAG RACING / Set up for an old Gen I
« Last post by HollywoodAlberta on October 31, 2021, 11:47:59 AM »
Hi Folks.
      I just came back to this site after being AWOL for a few years (I was gone so long I needed to take a new user name)and need a bit of direction.  I have just picked up a tired Gen I that I want to take to the drag strip in the spring.  It's stock length but lowered and has a front strap. What sprocket pairing should I use?  Have a Shinko on order so don't know what series but the dealer is a drag racer so he will get me a correct tire.  What pressure in the Shinko? Launch RPM? Shift with or without the clutch?  Had an airshifter before so don't know about the shifting and I dont know that I want to sink that kind of dough into this relic.  I don't know the history of this bike except that it has after market cush drive insert (the vendor said) upgraded clutch springs (he said that too) and a K&N filter.  It also has a Power Commander 5 and a Yosh exhaust.  I don't know if it makes any more horse power or just scares the daylights out of the dog.  Any other help, observations or advice would also much appreciated.

been quiet on this thread, so I decided to do a little resurch of my own,,

I haven't seen the 2021 SCTA,AMA tire requirement rules, but based on the DLRA rules which are one year behind the SCTA rules, it states :- "201+ = In excess of 200mph special tires for racing as designated by the manufacture must be used" note, there is no mention of tire's speed rating requirement,,

The Bridgestone R-11 is a tire specially designed for circuit racing (R = Racing), with a speed rating of "V" yes folks that's 149mph !!

However the Bridgestone RS-11 is a Racing/Street (RS) designated tire with a speed rating of (W) at 168+mph

The way I read this is that the R-11 being a "special" tire for racing is\was meeting the rule books requirements, however the oversight was the speed rating on this particular tire,,
I would suggest that the RS-11, with a speed rating of (W) same as the old Bridgestone 003 would be a better choice to use

Anyone got a Gen 1 Busa with a PC-V on it, need some wiring color help, got one here that has had the harness cut up and need to know what color wires go from PC to injectors, pretty sure I have the other end correct. Pics would be great!

HELP! / Re: Weird running issue
« Last post by RansomT on October 22, 2021, 06:45:58 AM »
I hate when this crap happens. Remember you are dealing with a bike that has a wiring harness that is more than 15 years old.  However, since you pulled the cam sensor and it reved better AND threw the same codes.  Like you are doing, I would check the cam timing...Intake that goes above 112, will act like that.  I personally would have swapped the cam sensor before pulling the cam cover, but it probably wouldn't have changed the problem.

 A good running 2006 1397 , I just had engine out and added the APE Gen 2 crank, ran great before. Now it acted like rev limiter and went flat at upper rpm, threw C-24 and C-27 codes. Plugs looked good, swapped coils --no change, swapped ecu--no change--- ran coils off separate relay-- no change, swapped stator and crank sensor-- no change, pulled cam sensor and it revs way better but still throws those same codes, will let it cool off then pull cam cover to check cam timing and pin height.
Any input??

Jim, when it happened you said that you thought something on track may have cut the tire,, now after what appears to have been a similar tire failure on Jack Frosts bike, your thoughts ??
