motocross pipe on scoot

[racerbugg]

just a thought, i can aquire a kx 60 pipe (FMF) for next to nothing and was thinking of mounting on the keeway.
54mm x 44mmstroke with the autotech 8 ports cylinder kit
and mounting it wont be a problem.
anybody done this or am i stepping into virgin territory?

All 2 cycle exhausts are a compromise. A scooter pipe trades a bit of top end for some bottom end, otherwise you would not pull away too well from a stop without a manual clutch.... a motocross pipe has virtually no bottom end, because the set-up has a clutch you can modulate to get going, you also have a manual gearbox to keep you in the operating rpm of the pipe.

Not to dissuede you, if you are a small light guy, the chances are pretty good you can make this work for you...... but a large guy, on a heavy scooter, would do better with a "scooter pipe".

IF the pipe is cheap enough give it a go. MX pipes have such a narrow power band though and at such high rpm it might be hard to set up for the street.

i know the FMF pipe puts more mid and top on a kx 60(and most other models of motocross bikes ive ridden) so i might just give it a try

I tried this a few years back,never would get on the pipe..Scoot engines have tiny transfers,reeds,and exhaust ports compared to MX stuff,but we'd love to see if it works for you!! :thumb:

I did this with an old nh 80 using an 81 cr 80 pipe , intake and carb. But never got around to tuning it. It was dull off the bottom and mid but once it hit 60 kms it pulled super hard ( for a 20 yo scoot ) up to 80 and that was about as far as it went. Then I sold it.

I would not think a MX pipe would fit a horizontal engine

it will with my talented welding and cutting skills.
