    Just wondering what issue's, if any, that would arrise from putting a muffler from a gt650r on a gt250r? The 650 muffler is a stock one but I cant argue with the price and my stock 250 one is banged up and rusty from being lowsided by the previous owner.
    I'm thinking, possibly, the carby's needing rejetting but not too sure.

    Dont think u would need to worry about jets .... I worked on this red Hyo here for a bit and it had an aftermarket muffler with the little baffle tip removed ... made no difference ... just a deeper note ..... cant see the 2 stock mufflers being much different anyway, if at all

    What would make a big difference in my opinion is if this resonator and the narrow pipe section was replaced to match the rest and a straight thru system ..... the Hyo always felt very restricted

    I am eventually going to replace the full exhaust and airbox but being a noob at mods im taking it one step at a time, plus I want to ride the damn thing, had it a month and only done 5km on it before I decided to fix the little niggling issues.

    I'm hoping to be back on the road by Christmas, just in time to cop a lecture from my parents for buying another motorcycle. Lol

    The main difference between the stock exhaust flange on both bikes is that the 250 has a 4 bolt flange and the 650 has a 3 bolt flange.
