Alright, so I guess I am going to tear my GO .21 5 PORT MODDED engine down and rebuild. It is 2 Gallons of Trinity 30% old. I think the front bearing went. The engine was acting like it had a nasty air leak and the lower crank case was getting wayyy too wet for me to be comfortable. Looking for some advice on how to rebuild this thing. I figure I might as well either replace the piston and sleeve or at least get it repinched.
1. Where do I get a main bearing for this thing?
2. How do I change out the main bearing? I have heard about an oven?
3. Are there other bearings I need to chang out while its torn down?
4. I am clueless as to what to do with the piston and sleeve.
5. What about other internals? Am I replacing anything else???
THANKS!
