Can't remember which of the thousands of engines you have been playing with, but if THIS one is one that had significant blow-by .... and you didn't have an adequate crankcase vent ..... then it's possible that pressure built up high enough in the CC to gradually push the gasket out. One would think the torque of the head bolts would be enough, but remember the torque on these mouse fart engines is like 1 pinky ounce. This is that old blowby engine, my first engine, I' going back this time trying to fix things and get it so I don't have to open it up again. This engine does not have a crankcase vent, it has a valve cover vent, which I assume are different. BTW - I realize you are addicted to wrenching your scoot engines ... but why not "become a man" and put a real engine in that thing?   |

rcq92130 I would if I knew how to weld and had the money for it. So everything seems good again now after finishing everything. Rehoned the cylinder, put new rings on the piston, put a head on with less miles that looks better, put it all back together and it definitely feels stronger and smoother, and ontop of that quieter! I feel the high end is lacking and the high end revs aren't being used to the full potential but I believe I'll experiment with weights and figure it out, plus I plan to get better final gears, but the engine issues are gone now. Oh and no more oil consumption issue

Oh and no more oil consumption issue R u running hih rpms at top end ? If your weijts are too light you will have high rpms but it will feel really weak . that is at top end |

If your weijts are too light you will have high rpms but it will feel really weak . that is at top end Yeah it does, I'm using 8g weights. I have to wait a few weeks until I can afford anything though. The low and mid ranges work great, and I normally do not need to go faster than 40-45 and I can achieve those speeds again now without issues or weird noises. I just feel the high end could have more power, it doesn't sound like it is going faster than maybe 6k rpm at the top, I remember how it used to sound when it would get to 7.5k, the engine sounds lower than that. |

I have to wait a few weeks until I can afford anything though. I just sold all of my lighter weights on eBay. From 9 to 14 grams. I sold about 60 of them for $17 fee shipping. I wish I still had some , I'd would have sent you a few heavier sets . |

The important thing is the engine is running great now without issues and I can count on it again to use as my passenger carrying and far going scoot, my 50cc is my town scoot again now lol.

I've almost put in the hundred to break in the new rings, been riding all day and haven't heard that horrible sound once yet. |
