thats pretty wack. my yamaha dealer here in town gave me an OTD price of 6900. when i got there he said oh yea, we sell these for 6700. i was like, wow and neato..hows that for cool?
good luck finding used rockets. ppl that by them dont turn around and sell them. minkia38 is your best bet for rockets. better get in line cuz they goin like hotcakes...
1 or maybe 2 main sizes since you are adding better air flow. shouldnt need anymore than that. go up 2 sizes and check your plugs. if its rich go back down one size and i would say you would have it.
haha yes cole i am smart. personally i would never bother putting a 125 engine in a quad frame. they have a hard enough time pulling around a 220 pound dirtbike let alone a 300 plus pound quad. if you wanna go single cylinder 2 stroke i would say find a used 250r engine. they are easy to come by and easy to get parts for cheap. you could always go with a 500 engine but they are alot more money even for a used one and im not sure that frame could handle it...
