This is the third bike I've built and I feel like I have a pretty solid set up. It's very smooth with considerably less vibration than my previous builds. However, I feel like I should be getting a little more top end than I'm getting. Here's the list of what I've got:
-New Micargi Rover GT
-Standard issue Chinese engine kit, 80cc
-Aftermarket expansion chamber with matching exhaust port gasket
-upgraded chain tensioner
-Billet rear sprocket and mount, 32 tooth
-Upgraded performance carb
-CNC aluminum intake manifold matching the port and gasket
-Boost bottle
-CNC Aluminum front motor mount
-NGK cooler range plug
Here's the problem. At higher RPMs the motor almost sounds like it's hitting an electronic rev limiter and just runs flat when it should be reaching the top end of the power band. It's relatively flat where I live so there are no hills, which is why I have the small rear sprocket. I feel like I should be turning more RPMs than it's getting. My other stock motor seemed to rev higher. I feel like with the tall gearing I should be able to easily hit 30MPH but it isn't happening.
What is the next step in performance mods? Can this carb be jetted differently? Is the upgraded CDI worth the money? Should I buy a ported and polished cylinder and high compression head?
What are the next logical upgrades to get me to the next level?
