WINDYCITYJOHN400 Posted April 13, 2011 Report Share Posted April 13, 2011 Putting in a set of Vito's Super stock pistons and a 4 mill crank is your best bang for the buck. You'll be a 385 and with pipes, stock carbs and V-force 3 reeds...you'll hit 50+ HP. You can see 53 HP with all that, a cool head, and pump gas.

gstaten24 Posted April 13, 2011 Report Share Posted April 13, 2011 Instead of doin all that have you thought about porting your stock cylinders? That will really wake the shee up! Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted April 13, 2011 Report Share Posted April 13, 2011 If you only plan to do a mild build pipes are your first modification to do, they will show a good gain. hp per dollar spent, porting is going to be the most cost effective modification. But, you should allready have the supporting mods lined out or plan on purchasing them with the porting ie: pipes, carbs/intake, reeds ect. Pipe selection will depend on your riding style. I would really have to disaggree with John on this one, I am not a fan of the Vito's products even though I have lines on them. -Brandon Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted April 13, 2011 Report Share Posted April 13, 2011 If you are looking for the most reliable and best performing big bore setups you should consider the CP Industries lines. Your riding style will really dictate which cylinder to buy. The Cubs, Cheetah's and Servals are all great cylinders and can all be bought for a stock stroke or for a stroker setup.

I wouldn't use their stock replacement piston. (It's junk.) But the super stock pistons have the lowered lip on the exhaust side and it really works well at simulating a basic port job. (It's not as good as a port job) But for only $200 it's something the average guy can do on the next rebuild and it will give a great power increase. We've had a solid 80 hours on them and they look good enough to go another 40+. Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted April 15, 2011 Report Share Posted April 15, 2011 I would skip the big-bore idea and just get your stock cylinders ported. Send them off to Kevin at Herr Jugs Racing and just go over your riding style and what you're hoping to get out of it and he will set you up with an awesome port job. You won't regret it at all. To take full advantage of the porting you need to do the basic bolt-on mods. Cool head, reeds, timing, whatever pipes kevin recommends for the porting you decide to go with... But best bang for the buck is going to be the porting. I would definitely give kevin a call. His number is in my signature. - Jared Quote Link to comment Share on other sites More sharing options...
