Re: Best motorized bike upgrades for 80cc
The BEST bang for the buck speed wise (which I am assuming is your ultimate goal) is a
smaller rear sprocket.....That will net the most speed per dollar spent....A 34T sprocket for $24.95 plus shipping is THE best bang for the buck and will still leave $$ in your pocket!
Engine wise lots of small things can be done to the engine itself (example port matching the intake to the cyl jug, milling the head for increased compression etc...) and best part of all...some mods are FREE or at least very low cost if you have tools on hand
Have fun tinkering....Ride safely!
