Would FST's(FourStrokeTechs) 390cc be a good kit to buy?
Im not worried about it getting to hot b/c of my oil cooler coming.
Would it be worth the time and money invested?

Yep...
I think ill go with the 330 kit first though.Ill probably have to get an oil cooler, and a oil tank to cope with the heat.

If you are considering buiding the engine up, you should know how much money you want to spend. If you have to have a stronger crank, hardened rockers, valve guides, stronger clutch, and sometimes transmission gears.
It can get pretty expensive if you want to go all the way with the motor versus just a bore kit.

I know a guy with the 380 kit which is the same as the 390 cept he got the 380 so he would have a couple overbores left..to say the least its awesome.....a raptor doesnt even come close....he has no problems without an oil cooler....
