Im running a set on my dune ported bike and i really like them powerband hits hard and pulls for a long time. bigboybanshee and john19 both rode my bike pm them and ask their opinions john19 runs rockets also.
PC it if you get a chip in chrome it will start flaking. as far as the same color as your frame i would say no. silver or power chrome i agree with a arms and swinger matching.
I refill almost everytime i go back to camp that way i dont have to worry about it, expecially since i dont have reserve now. As far as mileage i noticed a difference after being ported but i have a heavy thumb also.
Cheetah kit sizes:
400cc kit (uses stock crank)
421cc kit (uses 4mm crank)
485cc kit (uses 4mm crank)
510cc kit (uses 7mm crank)
535cc kit (uses 10mm crank)
553cc kit (uses 14mm crank)
593cc kit (uses 14mm crank)
610cc kit (uses 16mm crank)
heres all the kit sized the added cost will be from having to buy a crank for the motor lonnie at sandtrix in tulsa is running around 100hp on the 485 if i remember correctly.
There are alot of motor builders that sell them Patriot for one im sure there are others a&s, k&t maybey. you could always buy one from trinity unported and send it somewhere also.
