    M8s = mates. WRE(and SM) is somewhat de-tuned / street-legal version of the WR. I guess it was the A1 restricted (11kw) pipe whereas unrestricted is like 25-30hp.

    I found this from one of the biggest finnish 50-125cc bike sites:

    Main jet: 165-175
    Idle jet: 34
    Slide: 50
    Needle: d50
    Last one: 270 (cant translate)

    In general, to benefit from more/better exhaust flow you need more air and more fuel, so open up the airbox if necessary and richen the carb. Some details would help. If it was running well before and now it's hard to start, it's probably lean or flooded. Check the plug and buy a new plug or 2 if you're having problems.
    no pics=it didn't happen :cheers:

    You look in general to a higher nr of main jet

    there might also a richer needle needed in the set up

    pipe manufacturer could give you probably a ballpark nr of where you have to look at

    what type of pipe do you have?
