REMEMBER there is no replacement for displacement..

I have a set of 250e the liquid cooled ones. THEY are 250cc atv, not a 200cc atv like the 250d... they are cool but not like my Yamaha 450 wolverine, but I bought mine to trail ride with my kids, good cheap fun..

I have rode mine a little, and I think a 12 tooth sprocket, mine comes stock with a 428 chain, but better sprockets and adjusters will come in soon.. but I will break these first.
a CV carb would make a world of difference on these motors.. it would make more power, better starting. smother idle, and smoother acceleration..

I am not sure about ANY of these CDI boxes. I would like to see some curve data my self.
Or a 3* key way would be just as good. and I can make that my self..

The things that are first on my list,,
FIX LOOSE SEAT, doesn't lock in to front mount..
stronger better chain adjusters, ( make my own)
LED LIGHTING.
