A friend of a friend bought a brand new high performance Yamaha 4 wheeler. The dealer told him to take it easy for a while to break it in. The guy disregarded this advice and rode it wide open all day. By the end of the day it would not start or run. He took it back to the dealer and lied to them about not breaking it in correctly. The dealer did rebuild the motor, no charge. Some people have no common sense.

That crank being bone dry is a dead giveaway it wasn't getting oil due to none being mixed in the gas. If it had premix in it the crank and rod would have had looked wet with a film of oil on it when you removed it. That wiped out all the crank bearings and I'm surprised the piston didn't seize.

If you own a two-stroke motor, you have to leak-test it. Leak testing is not a gimmick or snake oil, people. Cylinder head and piston show signs of detonation, especially the piston. If you have bad enough air leaks and a leak test is not passable, then this is what the outcome will be.

@ar2043 Жыл бұрын

I agree. I would always leak test a two-stroke rebuild. Now I know there are plenty of mechanics out there who can do it and skip the leak test, but it just makes sense to do it so you know for sure you are good to go in the leak department.

My guess is one of three things, if not all 3, he ran it with no gas in the oil, some fools buy an mx bike and do not know you have to add oil to the gas. He ran it with no coolant in the radiator, or something in the cooling system was bad, a bearing, an impeller, or a seal. And who in their right mind pays $3k for a bike with the oil drain plug welded shut, that is insane. And if he welded it shut, he is insane, and dishonest for not saying anything about it before selling it. I would not pay $1.200 for a parts bike that has a drain plug sealed shut with JB weld, maybe $500 at the most.

Could have overheated because of no coolant in the radiator. I just rebuilt a 99 RM80 that had blew up 4 months after it was supposedly rebuilt. What I found was the 2 water pump bearings went bad and chewed up the impeller shaft seal. Most of the Coolant had leaked into the oil. The radiator only had a couple of ounces of coolant left in it which will definitely cause it to overheat.

@Antiquefarmequipment Жыл бұрын

Yea I'm think that too.... no coolant= overheating which would lead to locked up Bearings. And I don't think he had mixed gas in it. Probably put mixed gas in it to make it look good to sell. But ran it with regular gas.

@jcasey2309 Жыл бұрын

Just finished a 03 with the same exact issue. There was oil in the gas but it was jetted super lean. Once I finished it, I went as rich as I could on jetting without fouling plugs and I’m running half and half 110 and 93 non ethanol. Both of those things combined have made a night and day difference in how cool the engine runs. I’ll adjust the jetting a little leaner once it has some hours under its belt.

Maybe the skirt hole. But it was clearly an oil issue of some kind. Hard to bigger up that many bearing and the piston and have good case oil. Also I’m not there but that cylinder looked fried to me.

It seized because it was too lean. Cylinder can be replated if needed. Gotta do a leak down test for air leaks, fix them, then jet it. The spark plug should have little aluminum specks on it also that came from the piston when it was running lean and eating the piston away.
