I build a lot of pocket bike engines, squish is over 0.060" stock and I have taken them down to 0.035". That mod alone makes great power over stock.
This is my first bicycle engine, hoping to learn a lot. What is stock squish and how far have you guys gone with the squish?
I know these start around 6:1 which I consider low but seems to be just fine. I obviously haven't finished the motor yet. This winter as I have been cleaning up the intake and exhaust ports, I might widen the exhaust port as well.
Now, this is a budget build, $150 with bicycle, I am at $135, just wanted a few free mods to run a few buddies bikes. One will have a 66/80. Eventually I will build a 66/80 just so you know.
Thanks in advance.
