Jhughes7 Posted October 31, 2007 Report Share Posted October 31, 2007 I am thinking of buying a drag bike when I sell my bike, its a 7mill K&T Drag ported stock cylinder, 18cc domes, 38mm carbs, shearer BB OOF's, lock-up on 110. The guy said it pulls 95-100 HP. Sounds abit high to me being on gas? I know K&T builds a mean motor how close to true do you think that is?

Snopczynski Posted October 31, 2007 Report Share Posted October 31, 2007 crank dyno or dynojet? What size is the bore? Quote Link to comment Share on other sites More sharing options...
Jhughes7 Posted October 31, 2007 Author Report Share Posted October 31, 2007 Not sure on the dyno but I am fairly sure its dynojet, as for the bore, I am also unsure, but its an 06 motor so its probably not deep in the bores. Quote Link to comment Share on other sites More sharing options...

Snopczynski Posted October 31, 2007 Report Share Posted October 31, 2007 Its the first bore with 795 series I would say 88-90hp absolute max on a crank dyno. K&T does build wicked stuff, but I just donts see enough displacement to make those kind of numbers consistently. I do know we recently crank dyno tested a 6mm, 460cc, resleeved, and torque ported cheetah motor with pro circuit pipes and saw 92 hp. It made 87hp with ptr mids. This is all speculation, but I bet that K&T bike is really fast. Look at it this way, the superior sleeve 10mm+ stroked motors back in the mid 90's made 110hp on the dyno. You get to a certain point with a stock cylinder (470cc-510cc I think) and you just cant move enough air and fuel through them to make a ton of hp. Thats why we saw the introduction of the 4-6 different aftermarket cylinder setups that are now available. Quote Link to comment Share on other sites More sharing options...
Jhughes7 Posted October 31, 2007 Author Report Share Posted October 31, 2007 Yes thats about what I was figuring, 85-90 or so. He doesnt have an override and claims that it shifts just fine with the lockup, but I would think 100hp would shift like shit without an override. If I do decide to get this bike (If my bike would hurry up and sell). I will be switching it to alky and putting an override in. As it will be strictly a drag bike for me, and if I can set it up just right. I might actually win some drags at boxcar on the big weekends.
