Reliable motor work..

[DEAL]

I want to know what I could do to get more power out of my motor but still keep it fairly reliable .. Right now I have the hrc kit ..
so what now .. 11:1 ? 13:1 ? ..
I can't seem to find anyone that makes a 12:1 piston for it ...

I think CP makes one in the 12.? range. You can also get a 12.25 over at the org. from one of the sponsors , it is called a Black Widow and I believe it's made by Cp also.

You have exhaust?

yes, full hmf.

the HRC kit is good if you dont have that yet

id look into A BW 12.25:1 piston or the 14:1 if you want to run race gas

I'm tearing the motor apart here soon to replace the crank bearings before they fail. so I plan to drop a piston in it and maybe do some port work.. I just don't know how reliable a 13:1 piston would be if I'm gonna be riding 2-3 times a week.

the je 11.5 is a nice piece it has extra holes to get oil to the wrist pin. and 11.5 is very safe for pump gas. It works well in mine

how loud is your hmf? and ive heard they are the best for bottom end power but i want an exhaust that isnt extremely loud
