My 86 would rattle while idling. Never could figure out where it was coming from.

18:1 is plenty rich enough lol. Me I just mix it 32:1 right from the get go after rebuild and run it but same say a little richer after top end replace.
2 strokes have lots of pinging sounds like angry bees. When its idling just get down close to the quad and really listen and go around it to pinpoint a general area then go from there.

From what I've learned on here, GrkGuys' advice is very important. I'd hate all your work to get trashed cause the washers and bearings failed. It's a really cheap fix also. Go to the store at the top of the page, and get the thrust washers and rm bearing kit for a great price.

make sure piston is facing the right way, and install some billet washers and rm bearing.

Leak down test after your done and the  3    8mm bolts on the exhaust  only get torque to 8psi.

Go for it man.

If you are unsure about a step, just post some pics and ask. Its extremely rewarding when its all together and fires up for the first time.  +k2

Top end rebuild is quite simple. What are wanting to know or what is your confidence low on?
Ive never tried it with a motor in theyre always out but you should be able to pull head/cylinder with the engine still in the quad.
