Hey guys I have a grubbee 66cc. Skyhawk. On a Rockhopper.
I broke it in with Maxxim 927 castor. At 16:1 for the first gallon. Riding up and down the block for 10mins. at a time.I feel a very gentle break in. After the first gallon I went to 32:1. I have 2 gallons total run time.
Yesterday I was on a 54 mile ride. I stopped to have lunch. When I went to take off I noticed a strange wind on my knees. Stopped let it cool,and checked the head to see if it was tight. It was loose. So I took the head off to see if it was a blowen gasket. The gasket turned out to be fine.
I did notice however that there appeared to be a gouge in the cylinder wall. So I figured I was 27 miles from home. Im not rideing. So I reasembled the motor and limped home.
Today I took the motor back apart and its not just one gouge. Its several! Theres alot of chrome missing. It still has lots of compresion.
Has anyone else had this happen? I am going to run it until I can afford a new cylinder and rings. It just sucks that there isnt anykind of warrenty against deffects. I havent even had the kit 30 days.
I understand not knowing how it was broken in is a viable reason to have exemptions. But come on.
Before people ask, I wont say where I got my kit. I deal with them alot. I fully believe it is manufacturing defects.
