Like the title states.

2005 HONDA TRX450R = atv has fox float long travel front shocks, fox podium long travel rear shock, atv four play +2+1 long travel A-arms, atv four play +1.25 swing arm, durablue +4 axle, atv fourplay +2 steering stem, fat bars, precission steering stabilizer, rear douglas bead lock rims, douglas aluminum front rims, gauseted frame, HMF full exhaust, pro armor pro peg nerf bars, rear holeshot mx tires, front maxxis razor cross tires, vortex adjustable high rev cdi, plus extra tires, exhaust, axle and other parts...

I want to run on premium/91 pump gas. Any input on best way about doing this? I asked about the motor and this is what he told me.

Rt now it's a 14:1 Cp piston from venom performance , u can run a 12.25:1 piston from them on pump gas. The piston is about $250 just so u know what u r getting into dollar wise. Stock piston is 11:1 u can go that route too. I ran the 12.25:1 in my yfz it worked great. The atv comes with extra set front and rear race tires, extra sub frame , extra Leo Vince slip on exhaust, stock head pipe, and bunch of other extra parts.

Let me know what you guys think. Things i should check, look out for?

dont get me wrong i really want it. Thought id post it in the 450 forum as well. I want the most power i can get and still run pump gas. Wouldn't i need to change the bore if i get a 12:5:1?

^^no 12:5:1 is the compression ratio the bore size is in millimeter such as 94mm you wont have to change anything exept piston and gaskets
