Well, as some of you might know, I have been running and breaking in a 70 cckit made ESPECIALLY at ChrisMWH's request over in Italy by a friend of his.
I bought 2 of these.
VERY FORTUNATELY for me, while getting ready for the long run up at Lake Erie, I decided to remove the Mag cover and check my points.
I was EXTREMELY surprised that when I turned the mag to TDC, I felt a definite click over(NOT compression caused)as if a tension had been released somewhere in the crankshaft dynamics.
Well, I hadn't heard any noises, so I asked a coupla' of pretty good 2-stroke guys what they thought. They BOTH said `run it'(`course they don't care for mopeds,either..LOL!).
Being pretty cautious tough, I took the head off just the same. LO and BEHOLD......the Piston was tapping the head, just as I had suspected!
The ONLY damage appears to have been to the wrist pin and upper bearing. I got these at Handy Bikes Wednesday afternoon and re-installed them before work. I found a little longer wrist pin at Handy Bikes that fit the 70cc piston better.
I have to take the head I had a squish band lathed into, or else use a thicker head gasket now. Apparently it was just too close to start with.
I may get the squish changed tomorrow at my Buddy's machine shop.
I was also surprised that after hundreds of break-in miles that there were still `cross-hatched' hone marks there. But compression was really high before, so that worries me not.
We'll see how it does........it's gonna get a LONG test run Saturday, I hope! don-ohio (:^D
