You had to turns bolts to install reeds! :woot:
You are on the original bore that is 7 years old, I would get the port job and a new top-end with it. Your compression might still be within limits, but it would be advantageous to do them at the same time. Bigger carburetors would compliment a nice port job and CPIs...
If $500 is the max, shave the stock head, timing plate, and lighten the flywheel for now, save the rest for the port work and top-end.
