Blown oil seal?

[Bansheerider29x]

Yesterday i went riding on my shee and it didnt have power most of the time. Sometimes the right side didnt have smoke coming out of the pipe. So i go and check the spark plugs and one was a light brown, while the other was black(like carbon not excess gas/oil). I put new plugs in and it ran fine for a few min, then it wouldnt. Also before this i had the same problem but it was the reeds but i got new reeds now. Do you think its the carbs maybe becuase my dad says its an oil seal and i dont want to tear it down to put new ones in. What do you think becuase i need this help badly!

If there is no unusually heavy smoking

from one or both exhaust pipes and your coolant and tranny oil levels are

not dropping then it may not be that serious. If compression is good and even

on both cylinders you might try swapping plug wires from side to side for a quick

easy test to eliminate the possibility of a bad plug wire. If you then start fouling

the plug on the other side, replace the plug wires or coil assy. You didn't by any

chance recently have a fuel leak and conveniently "fix" it by re-routing an overflow

tube to a higher location? Could try swapping carbs from side to side and see if

the problem moves to the other side. There are other possibilities but you need

to check your compression FIRST.

I am having a similar problem. The bike runs and sounds great through the first 3 gears and then it just falls on its face. I overheated the bike last weekend and a white oily foam came out of the overflow hose. The radiator was really low and there was no fluid in the reserve tank. I filled both the radiator and reserve with water, which was all I had in the middle of the Glamis dunes. About an hour later the same white oily foam came from the overflow hose. Does this sound like an oil seal?

I thought with the addition of the water in the radiator and the reserve tank that if and when it overheated again the fluid coming out of the overflow hose would be much more water-like. Any help would be appreciated.

Thanks in advance.

No i havent had any leaks lately and everything has been toped off. I have full tranny fluid,radiator fluid,gas and everything. I tryed swaping the plugs and no difference. I just called my local atv shop and they said it could be the float bowls being unlevelor carb related problem, so im gonna go and check both carbs and i will reply when done.

So I assume the radiator fluid level was low again. Make sure your tranny oil is not milky white or overfilled now which would be a bad waterpump seal or oring. However, it sounds like you are burning it by the way that you describe the bike running which means you need to replace the head gasket (or o-rings if you have an aftermarket head). Easy fix.

 

Bansheerider29x let us know if you figure it out, but I can't help you any further

without first knowing what compression each cylinder reads on a compression gauge.

[Bansheerider29x]

MY compression is equal and high on both sides(i also just did a full rebuild a few hours ago).

What have you tried so far and explain again how it runs when you test ride it. How many NEW plugs have you fouled? Explain to me again what you are saying...it runs good with the new plug for a while (how long?) and then you feel it start to mis-fire

or what? Have you checked the carbs yet and/or swapped them from side to side?

What does the exhaust smoke look and smell like? Your symtoms are pretty

vague so far. Are both pipes getting hot when you ride?

[Bansheerider29x]

I cant swap the carbs cuz the way the choke is setup i cant switch them around. But both pipes get hot besides the right side is slighty cooler than the left sometimes becuase the right side doesnt fire all the time.It cant be the eletronics because all mine are new and it fouls a plugs after a few min or riding and sometimes it doesnt. The smoke always looks and smells the same even when it was running right. Im so lost of how to fix this, if anyone one else has had this problem tell me what to check over please.

[Bansheerider29x]

I just cleaned the plugs,tighten the caps,kicked it over to get rid of any excess stuff lefted in the top end. Then i started it up and oil was coming out of the end of my pipe not a lot but enough to get all over my hand when i put it over the pipe. I took it for a spin around my road and when i checked the plugs they had some oil on them. and right now both pipes are running.It just got alittle warmer so am i just to rich or what? Im having on confusing problem!

The radiator and reserve tank are still full. I will check the tranny oil. Thanks
