Hey guys I have a question for ya

My uncle dropped off my cousin’s lt80 for me to do a compression test on it. I knew it was lacking compression because when I turned over the engine to start it sounded like the plug wasn’t even in. so I did the compression test and I’m runnin about 50psi. Now my question is what exactly is the recommended compression for an lt80 because I'm pretty sure it’s got to be more then 50psi

Any thing over 100psi is good but closer to 125psi would be better.

i sorta figured it should be in the 100 range

thanks for the info

I am thinking around 125psi would be good for a stock motor. we are at 180psi on our Mod LT80 motor.
