I just put 20" turf tamers on my 250 Big Red, and they are awesome but they almost totally rob my top end power. Are there any mods to get my bike back up to speed without changing my tires back? I was thinking a new pipe and bigger jets in the carb.? Any help would be great. Thanks.

 

I was gonna say change the sprockets and then I remembered, it's shaft driven.

I think you're just going to have to put the other tires back on.
