How to make a tow stroke exhaust for a 135 cc yamaha motor bike for racing?

Answer 1

I take it you mean two stroke.

Very hard items to make.

Take a look at this : http://www.scooterwest.com/files/items/0... basic scooter pipe work.

Very tricky, but thumbs up to you if you can do better then the pros.

My advice, just buy one pre built.

Answer 2

The only Yamaha 135cc that I can think of is a road bike and it is a 4 stroke so perhaps repost the question with more information and then you may get better help

Answer 3

i don't think you know the first thing about "motor bikes" and two stroke exhausts and racing. there is no 135cc yamaha motor bike, if you mean 125cc, yes that's a 2-stroke. how do you make it for racing? well, it already is for racing. so i'm just going to leave it at that - because it's all you seem to need to know.
