Default Re: No need for speed

You will likely get the extra speed you are looking for by simply getting rid of those stock mufflers or at least knocking all the junk out of them and drilling 4-5 3/8" or larger holes in the bottom of it so the engine can breathe better.

The slower bike was accidentally run for a while with a very rich oil/gas mix and I thought it might have clogged up the muffler but I haven't checked it yet . Is that a good place to start and will break in increase speed 5 to 7 mph ?
