Did you bore it over any or just the standorad bore? You still have stock cam or a aftermarket? Can you tell a big differance? thanx for help

 

Hi SYKOQUADRIDER
I used the std. bore.(11:1)
I put in a cam also it is a web cam they call it the drop in one.
It it the 461/496 grind. Works pretty good alot more power.
I have a 12 tooth in front and 42 tooth in rear it now comes up really easy now.I have this gear ratio so when i ride with my son i do not have to ride the clutch as much.Lost a bit if top end with this gear ratio.

happy trails

 

How much HP do you think you gained with the Piston/Cam combo? Also with a aftermarket exhaust? How much more sdo you think I owuld gain boring it a little? Thanx for the help nd what was the prices and where did you purchase both at. Thanx again

 

I have the yamaha exhaust on mine. hp gains not sure.
The cost of the piston was around 130.00 (atvaddection)
They have the same one i got on e-bay for 100.00
The cam i got at shop called LEIGHTONS CYCLE it was 165.00 with the core.(web cam)
