If you can save your jugs, Just send them away to get ported. Most 2 strokes need to be reved out pretty decent to make power. Or vito's has a new engine kit you can buy. I think its a 66mm? with the +4 stroker crank with the long rods. I have a vito 421 68mm big bore. I love it. But it makes its power up high. No low range. Alittle mid range. Quote
lms1977 Posted September 5, 2011 Report Posted September 5, 2011 get the serval it will pull the hills much better if you have to lift and get back on it but you wont get the same top end as a cub Quote
locogato11283 Posted September 6, 2011 Report Posted September 6, 2011 Cub = drag Serval = dune and woods I would recommend the Serval for you. Check the Sponsor Spotlight section. M&M ATV had some killer deals going on for Serval motor packages. Or just give them a call. Quote
dirtydownunder Posted September 6, 2011 Report Posted September 6, 2011 the serval can be ported into a cheetah cub and in between. so if you want to move your power higher, your just a port job away. Quote
camatv Posted September 6, 2011 Report Posted September 6, 2011 id do a serval with proper set up. and porting before it was even assembled.. Quote
