Has anyone out there changed the original JM250cc carb for a Mikuni 30mm carb to see if theres any big difference in performance or better power? Also does anyone know how to re-pack or make the muffler sound better than it does stock?

 

Have you done anything about the Air Filter yet?

Here's what I did to mine - made a HUGE difference (about 20% to 25% more) in power.

 

I havent but i should try it out its cheap and looks like it works good. I first have to fix my Rim cause its bent and i need to bend it back in place cause the bead wont sit right. Ive just been busy as hell traveling for my job and other things at home that its been sitting in my garage for 2 months and haven't ride it this summer. But staring this weekend or next week im going to get back on the move i miss not riding. Although last weekend i said i bet it wont even turn on even if i try. Well luckily turned and choked it for a minute and fired right up no problem i was surprised.
