Ok i got my a back together ( thanks for the help ) now I'm starting on my little boys 51 G it dyno at 47 hp with lots of blow by. Im looking for around 65 to 70 hp without any thing major done to the crank thinking new pistons lengthening the rods to get the compression up around 8 to 1 working on the head and shorting the rocker. Will i have to get a cam it has the 900r in it now. Just wondering if I'm headed in the rite direction and looking for any advice i can get. He is only 7 so not wanting to go crazy he was in the top 3 last year in 5500 so he is hooked just trying to get a little more. Thanks for any and all help
 
You are heading in the right direction, you will need more than 8 to 1 to get 70 though. If you want to talk and share ideas give me a call 9892775366.
