I wanted to take advantage of the Treats 15% off coupon so I just grabbed a DR 70cc kit, I'll be getting a new carb as funds allow. The Urban is completely stock (except for the BX31 belt) and runs OK but certainly has carb issues but its on the way out anyways. Questions I have to get it road worthy with the DR....

1) Is it necessary to replace the head?

2) Is it necessary to replace the crank?

3) Jetting range with stock exhaust?

I'm not looking for anything over 40mph and will be happy with the upper 30's in case that affects the answers to the above questions. Currently hitting a solid 32 but horrible take off due to the BX31 belt which I like to replace.

Thanks, Matt
