A buddy of mine is building a Magnum for his 15 year old son. He wants it to be torquey and not worried about top end, just mid and low. He just doesn't want his son riding super fast.
He bought an Athena 60cc kit, but wants to run the stock carb 14/14 Bing, stock air filter and stock pipe as well.
He left the stock jetting just to see if it would start. I'm not sure what the stock jetting is, but would putting a 60cc top end on there make it run rich?
It just doesn't seem right, but I dunno. The only difference is the 60cc top end. He's also using the stock 50cc high compression head...
Anybody running a similar setup?
