IMHO, before you start any build.
You need to pull the head off and measure the compression ratio the lil engine has now.
Jus sayin, You need to know where you're at, so you know which direction to go.
I see around here, alot guys putting in bigger cams, scratchin their @sses and wondering why they are gettin smoked by heavier riders with smaller engines and smaller cams.
These lil engines have to make low rpm torq, before they can make high rpm horsepower. The easiest way I found to do that, is bump up the CR 1st thing.
Keep us up to date on your build, and good luck.
