reaction 150 mods?

[angyhick]

Im looking to find out what kind of power I can expect to see after upgrading a stock 150 with bigger carb, air intake , exaust open and a sharper coil. Has anyone done this and is it worth the effort? Will a 250 mount up to the 150 frame? and how do they perform in the sand?
Just want more power!

Ever think about a snowmobile engine? It takes a bit of fabrication but waaaay more power than you will get with a modded 150 gy6. To really get the power you need a big bore kit, which you will need to bore your case, a Stroker, performance carb, performance exhaust, cdi and coil, and what ever else there is. Well over $400 for ALL of those to get maximum performance. I weighed out all thoe options and decided sled motor was the way to go. If you want some help with some plans, let me kno, im still in themist of mountimg my sled engine on my twister but I have it all planned out, even the orginal reverse off the 150cc motor.
