Hey guys, new to the forum. Just gonna ask to see what you guys think...i have a coolster xr-2 with a 125 cc chinese engine on it. I have put quite a few aftermarket parts onto it as when i bought it used off ebay it needed some work. Question is, if i want to put a piranha 150 or 160 in it(let me know what you guys think about this engine) is it even worth it or would i be better off buying a better frame and building custom and taking stuff off the other bike? Is the xr-2 frame any good or should i invest in a new perimeter frame, either american or even a chinese perimeter frame like the orion? How much of a performance and speed upgrade would putting a better quality engine in it? Heard mixed reviews on the chinese engines in the pit bikes.
Also want to know how much of a performance and sound upgrade a new pipe (fmf power core or pro circuit etc) would be if it already has a chinese pipe on it that came with the bike I'm guessing.
