Looks good Chuck. What combination of bore / stroke are you using t get 1407 (83 X 65)?

Assuming it is a dry shot, what size solenoids are you using and what controller? Just curious on that, we are re-doing a nitrous setup due to it being pretty much on ridable and not controllable with the way it was previously setup with baby spray.

Thanks- yeah, 83x65. Wet shot.

nice.

On another note, what is your current price on a tranny job for a busa?

Is it on a drag bike w/ wheelie bars? If so what would it run in the 1/4?

Can see but it made on spray ???

Nice numbers Chuck.

Couple questions:

Was this build like a motor build and nitrous put on top or did you build the motor strictly for nitrous?
Are these numbers Std, SAE or Corrected and weather conditions if you have them?
What this like a 200 shot of gas?

I'm just curious. Thanks.

have you run the bike yet?

Chuck Wilburn · « **Reply #13 on:** August 25, 2011, 08:05:20 PM »

Sorry guys, didn't see the posts. That's my pro-mod bike. STD correction on motor and nitrous- 213 on motor pulling a 26lb rear tire. I've run it all year- 1/8mile only. Best pass of 4.34 spinning pretty bad. haven't hurt anything other than we yanked the output shaft out of the cases, bearing support wasn't strong enough- it is now..... The nitrous pull had a 3second build time, the pull was 2 seconds so it would show a little more on the dyno if you could hold it to 100%. Have a little bigger nitrous jet in now but no need to put it back on the dyno, just been tuning at the track with the WEGO. Obviously, motor was built for this amount of nitrous.

Here's the video of the 4.34 pass- crappy pass but still pulls really hard-

still couldn't get the bike hooked up in first and second, we're working on it though.

Not bad for no power.....

Chuck Wilburn · « **Reply #17 on:** October 23, 2011, 08:26:16 PM »

Hard to see- 4.209@173.25mph.
