frogman said:Well it is my latest, well they are. ;D A 1972 CB450 more or less complete, a 1971 Cb450 in pieces and missing the engine, and PILE of parts. Total cost $425 bucks (25$ for a uhall freaking trailer). Pretty much basket cases but hey, I like crazy chicks. ;D :

Used to be able to get various tuning parts for them.
Motor is a bit heavy for a 250 as it has basically the same dimensions as 400.
Leave he oil pump on it, works well and the weight isn't a big issue.
They respond real well to some porting, reed block modification and a good expansion chamber. (plus, modfy air box intake but don't remove it)
I'll see if I can find any pictures of right side of my 400MX as it had 250 'race' exhaust on it (may be able to work out dimensions for a low level expansion chamber?)
After I finished messing with 400, I was running 14/47 gearing instead of 17/43 but it was about 25mph faster. (110ish)
Went from being a high torque motor (red line 6,400rpm) to an 8,000+rpm nutter animal
BTW, I know a LOT about C15's
No problem, glad I could help. I had pretty much the same learning curve about 3 years ago... I have a DS7DreadRock said:LOL not nit pickin !
