thank you, beast! Unfortunately, with only 40 something miles on it, AND I babyed th' heck out of her....th' upper roller bearing on th' rod spit little itty bitty rollers inside the engine!????! The upper roller bearings are a Great idea......its just that th' cage holding em was some cheap, thin metal!

The 2nd from last photo is an old engine, I'm gonna try rebuilding th' upper head/piston. Final pic is my super modded exhaust. I'm trying low buck , high concepts. Stock muffler is dremmeled open........with an aluminum cone bolted to that.............lined with scouring pads i commandeered from work where I cook

..............plus, an aluminum tube for a baffle with roughly sixty holes punched thru it. Sorry to get off track there............... has anyone else had a problem with th' newer engines?????????????
