compression under 110 get's is questionable.
check your crank bearings and seal.
also clean carb and check float level

Exhaust power valve adjustment for "stock setting" is: 1/2 turn out from closed.

The problem is common in 2 stroke watercooled bikes ,what happens is the head gasket leaks and the leaking burnt gases pass the gasket and sneak into the water jacket which highly compresses the cooling system and blows the water past the water pump seals and into the gearbox,mixing with the oil and making a vile mayonnaise mixture,make sure when you fitted the seals you fitted them the right way around the main sealing lips should both face their fluid they are keeping out and the impeller shaft should be free from and scoring or damage where the seals touch it.p.s im a fully qualified motorcycle mechanic with over 20 years experience so im not just guessing at an answer

It dependes on who you ask or which manual, you read but the main names are
counter shaft seal.
or drive axle oil seal
or drive shaft seal,
or sprocket shaft seal

the transmission shaft that the clutch is on is called main axle, the sprocket shaft is called drive axle\counter shaft

trail riding d'idnt provided enough air to make you're bike running cooler..and get you're head to warp a little and let pressure in you're cooling system. at least i would try a new gasket and some coolanol coolant to put in after....they get faster heat transfer..also you can put a higher pressure radiator cap that will keep in you're coolant...

sounds like the float is not working properly , could also be the jet. would be a good idea to buy a carb kit, not very expensive and save a lot of grief.

Posably a bent or broken reed remove and inspect reed valve

Yes, it is a valve problem. It sounds like a weak intake valve is dishing / stretching due to overheating. The exhaust valves are made to better withstand the heat. Check for cooling problems when you replace and seat a new valve.

If it was white smoke coming out you may have blown a head gasket. If it is water cooled and there are no signs of external leakage then it only has one other way to go, inside.
If you have an oil dipstick, pull it out and check to see if your oil looks more like a milk shake sludge. Even if you can't see it, try dumping your oil from the sump and take out your oil filter. (unless it is a 2 stroke)

Exhaust Power valve setting for stock is: 1/2 turn out from closed. **3/4 of a turn for extra low-end grunt. [all varies depending on jetting selected,..start at stock 1/2 turn out ... and X-periment from there] .

alot of four strokes will lock up like this they get vapor locked the best thing to do is let it set do not try and start it until it free's up it could bend the valves but i dont kno about the smoking unless you tried to start it while locked up

Hi,,first thing to check is the valve stem seals,,,then id be looking at piston rings and checking the condition of the bore.

unfortunately it involves removing the head.

good luck.

If you are running 5th gear mid throttle the compression in the motor wasnt enough to push the piston back down

try to keep it the power band you will be fine

good luck.
