Found the exhaust gasket torn on the bottom. I assumed this is causing high idle.. so now I am worried that motor has gotten dirt in it.
So I have taken the engine apart and noticed the button head o-ring is also torn toward the back of the engine. Has me wondering about internal damage so I have completely disassembled the engine. I did find the front bearing with some roughness in it. So I have ordered replacement o-ring, front bearing and gasket and am now going to reseal engine upon assembly. Not sure why front bearing has started getting rough or how the o-ring under head button could get torn.... will listen to any suggestions.
Bugy or truggy version ?
The O-rings under the head usually end up getting compressed and will get small tears....pretty normal...There is no way it can damage the internals, its only a dust shield/vibration damper
17011 bearing is a top notch bearing.....only way it would get gritty is if it ingested some dirt into itself.. Being a double shielded bearing it is not the smoothest rolling in your fingers.. I would pop the bearing out, pop the shields out and give it a rinse.....I doubt the bearing itself is damaged, you may just have some grit between the shields....use some brake cleaner and rinse it out....
And please do not use any sealer on the engine, it is not needed and not advised on a Novarossi...usually makes more of a mess then anything else....
