Pipe question?

[vindell]

Will a 90cc pipe work on a 70cc koso cylinder? I believe it is either a koso pipe or a hetrick. Also what type of gasket do I use?
Can I make one from gasket material.

c'mon guys, dying to install pipe??

Yes and yes,

It uses a normal gasket. You can make one if you want. Just make sure the opening of the gasket is not smaller than the exhaust port.

your gonna have to do a plug chop on it and see if it needs a rejet.I always run mine to a good temp.then cut it off and install a new plug and then run it out and check the plug for a nice almond color.
