I hate my PO

[vanaman]

Well end of the summer i bought a 84 200x that ran ok and smoked abit. I figured i was paying a fair price for what i was getting.

Lately its been running horribly and smoking like it always has. So i enlisted a friend to rebuild the top end for me. There was atleast a tube worth of red rtv on it instead of gaskets. several of the oil passages blocked and the cam is trashed.

The head and rocker cover should be salvageable. but i need a new cam, jug, piston and rings.

i hate people who work on things that dont know what they are doing.

ok, here's my new rules.

You know it's common for people to ask for I.D.?

Well, when some people go to buy tools, they should need to show an I.Q. card.

I'm so sorry man.
The only thing worse is some wingnut blowing up or wrecking your trike.

Same kinda feeling, I guess.

top end berrings shoud be changed to they probley had no oil

My trick with blueseal or permatex silicon is to spread it super thin
and tapered to the outside ( a tad thicker on the outside edge) and let it dry.

Then when I carefully tighten stuff down, I can see a little bead of sealer try to press out
and I know LESS than what I can see on the outside is being squeezed towards the inside.

If there IS a gasket, I usually glue them to whatever comes off, like the cover and let it dry.

Never had a prob with 3m weatherstrip adhesive for that. Good to keep rubber seals from walking out too.
Then maybe the thinnest possible skim of blue silicon on the gasket, let it dry and it will never leak
or squish INto the internals.

It's like adding a thin rubber band to whatever you're trying to seal.

Unless it's a machined mating surface where a 1/2 thousandths would mess something up.

Top end bearings..... And where exactly does a 200X have top end bearings? You make me want to punch myself in the face.......

[tri again]

do 2 stroke engines have roller bearings on the crank and wrist pins too?
maybe?

I wonder if caged rollers would be a reasonable fix for melted cam journals.

Thanks for the heads up on the zinc oils and aluminum btw

no roller bearings on wristpin in a 200X 1st gen

Megacycle makes a bearing conversion kit that covers both ends of a 1st gen 200X....the kit is supposed to be able to use the heads with trashed cam journals without any additional machining...bolt-in...runs about $350

Powroll makes a cam with needle bearing conversion on small journal end only...might be some others
