High Comp piston/cam

[406elcamino]

Im thinking about getting a high compression piston 10.5:1 or a 10.75:1 piston and a midrange cam .430 lift

just wondering what the hp increase would be?

expensive gas

yamaha350r if your worried about gas your in the wrong sport Mid grade gas or even 91 octane is'nt that much...I have a 10.25:1 piston and stg 2 cam and I was very happy with the increase. It makes the quad a hundred times funner to ride but i kinda wish i would have had the head p&p while i had the motor tore down but oh well. You'll be very happy with the power increase not sure exactly how much hp though but its much more of a gain than a pipe/filter.

Expensive gas? 30 cents more a gallon is expensive? It's not like you need to run race gas. I run friggin 93 in my van that gets 10 mpg on a good day.

But that sounds like a good combination. That piston might only give you about 1 hp, but it'll let the engine rev a lot quicker. You'll get a much more notciable power gain out of the cam.

You could expect around 28 HP. Pretty good IMO.
