Need moooooore horsepower.. my 220/249cc engine has about 16cv..
i remove electric starter and starter gear reductive.. it revs a little better..
i’m planning to remove the starter gear behind the magnet/generator.. but i don’t know if i have to build a spacer..
- may be change to a nibbi carburator (32??) could increase a little bit…
-any other ideas???
