My avatar... I asked OpenAI's DALL-E art AI to paint me a picture of John Coltrane playing a goose as though it was a tenor saxophone. The result is disturbing, yet compelling.
I live in Lost Angeles under the Smog Berry trees and grew up locally with BMX, Mountain Bikes, Go Karts, Mini-Bikes, and Motocross.
Hey I'm trying to get my motorbike up to 80mph. I installed a window port piston but it's the only thing bogging it down n making problems. 1yr of BS. I tried a HP carb, a PZ22, etc. But there's gotta be a way to increase performance of 80cc engine. I want higher HP, higher low end top end speeds, faster acceleration, better control, etc. What's everything u have to say bout that?

I think the window port piston is the root of all the problems. But it's "suppose to work". Maybe the window port is too big

Hi folks! I'm brand new to motorized bikes. I picked up a Tanaka QBM-23N motor (has the square engine cover), but all the fuel lines and vent lines have been taken off. All that remains is the primer bulb on the gas tank. Okay from the primer bulb the fuel line should go to the "in" arrow nipple on the fuel pump, right? What's next?
