YZ 125 compression questions, race fuel, pump fuel
Just rebuilt the top end on my 125 with a fresh piston and ring, and a cometic thin base gasket.
What is the stock compression?
What is the max compression that can be run with pump fuel?
When do i have to run race fuel?
What is too much compression for a 125?
I havnt checked the compression yet but it seems pretty high and i just wanted to make sure im doin the right thing.
I dont just want to be another guy, with a pipe and a payment...
