Hey I have a 50v and was wondering about what would be best to run a 70 cc head kit on my engine ?
I know there is post already about this
I have the head ported and milled with WIKI instruction, I could port more and get a little more but it’s a just a fun zip around thing
Also I have a 15/15 Sha carb and a 55 t rear sprocket and also the 12t front .
With the stock gearing it goes 39-40
My question is would it be worth it split the bottom end and do crank up with new crank bearings and piston and head kit
Or just re tune and ride the stock engine , thanks
