You want that much,... you probably want a bigger bike... Bad news is,... you probably only have 28hp or so,.. now... rejet, muffler, and air filter,.. might get you the 33hp.. |

Don't think it was a rev limiter. My guess is that the stock exhaust reached it's max flow, the operator felt the effects, saw that the bike reached it's limit and let off the throttle. I've hit that limit before when experimenting with different baffles and to a lesser extent different intakes. BTW, now I know for sure what 6K+ rpms on this motor sounds like. I can say with certainty that I've never hit 6500 rpms with my motor. Truly sounds like she's gonna blow up! Here's mine: (see below) Max HP: 33.19 Max Torque: 36.40 ft lbs Temp: 87 F Setup: 55 pilot (no bleed holes) 1 washer 155 main A stock bike seems to dyno about 28-29HP. The LS650 with Sportster muffler and 1/2 spacer ran 29.8 HP. The Supertrapp guy said peak 28 with stock muffler then his Supertrapp tested similar to my bike HP wise with 32-33 (no torque curve or numbers though) with air temperature of 22 degrees cooler than my run today. Don't know if that makes a bit of difference though. http://www.thumperpage.com/articles/ls650exh.html [/quote] http://i255.photobucket.com/albums/hh128/russ_diamond_jim/dynorunS40dj.jpg You might get 50+ by turbo charging... one fellow here is talking about it... search It's been said that 50 is max otherwise. It'll take a new carb and air filter, level 2 cam from lancer, some exhaust porting and a new header. And a lot of dyno work. With a edelbrock QSII, I was able to take a stock with supertrapp from 82mph uphill to 97 with a pause in the middle to coordinate a pass. |
