Ok I had a shattered piston skirt and a hole in my engine case
but the bike still ran ok but lacked major power! The piston was shattered on the intake side of the piston. I did a quick top end rebuild 10 over just to get me through the riding season last year but I didn't notice the crack in the bottom of the motor. I had a skid plate on so the engine case would be protected! :ohmy:
I always ran a maxima 927 @ 32:1 and kept the airfilter clean. Ran min. of 92 octane fuel and changed the transmission oil as suggested. The hole was just a crack at the case halfs but I lost much crankcase pressure. Being that the bike was a 500 2 stroke Honda CR it still did have quite a bit of power but I noticed a big loss in compression when kicking the bike over. Hey it usually would start on the first or second kick! One of the signs of trouble that I noticed was overheating while riding tight woods trails or on long steep hills. I got hot but not to the point of worry. Tom at the Honda shop said "It's a 500 just ride it you'll know when it needs rebuilt"! So after the first season of play riding real hard I parked the bike for winter. The next year I did the same thing and towards the end of the third year I'm really paying for not at least re-ringing the bike! I'm thinking that the rings just were worn and the cast cylinder/piston clearance was causing excessive wear on the connecting rod and crank&bearings. Anyways I decided to park the bike last August and start tearing it down and here I am today still not riding! Soon I'll be going again but not soon enough! I kills me to see everyone ride by and here I am stuck! I'm going to start a new maintenance program..."Pay Now or Pay More Later" Well the bike is back to brand new condition (2000CR500) and the motor has been shipped to Eric Gorr for a total rebuild! Well I figure that if I would have almost enough in rebuild cost that I could have just bought a new one ...... Almost...... Any suggestions on my Maintenance Program!
