Crank Case Drain PLug

[Guest]

I can not for the life of me get the crankcase plug loose. I have a 650g, which means that motor oil is filled and applyed to both the engine and the crankcase. Heres the situation:

• Drained my old oil from the main plug underneath.
• Couldn't get my plug socket to fit above the exhaust pipe in the nook where the crank case plug is. Decided I would temp. not drain the crank case. Then I refilled with fresh oil.
• Added way too much oil, Rode the bike around for a day or two , got nervous about having too much oil, and drained the oil again.
• This time I tried using a vice grip to get the crank case plug unscrewed. Only thing I did was begin to strip the bolt. gave up.
• So I added another batch of fresh oil again to the fill.

Is there a chance that some of the fresh oil has migrated into the crankcase?, now that I have changed out the oil several times.

Any recommendation for getting to that plug?

Tap on the bolt a little with a hammer. Try a pipe wrench now since the head is screwed up anyway. It will bite better than vise-grips. If that doesn't work it's time to pull the pan.

Is the crank case plug attached to the main pan?

Mine was very tight as well, and I was worried I was going to break/strip something, but did you try taking the bike for a ride first and get it warmed up good? I did that anyway to get the oil warmed up so that it would drain better/faster...just a thought.

I would stick to using a socket as well...in my limited experience you can apply a lot more torque that way anyhow, without the danger of stripping the head.

I would also think that some of the fresh oil would circulate to the crank case...

What color is the oil in the sight level?

I am changing mine at every 1000 km until it does not look black right after I change it.

I am sure someone will come along with some better ideas/more info than me as I am a newb at this, but...

Good luck.

hey there,

yeah, I tried when the engine was hot. no luck. I sprayed some wd-40 to clean it a bit. Still no luck. When the deep pocket plug socket wouldn't fit due to clearance, I used a 13/16 reg. socket and still didn't have clearance. I really don't want to have to take the exhaust off while its hot. I actually would prefer not taking the exhaust off at all.

No, not if I remember correctly...and check out this diagram - I think 40 is the crank drain plug...

Man, that sucks.

Unless there is some type of penetrating oil that might work better then WD-40, the only other thing I can think of is sliding a steel pipe or something over the socket handle to give yourself a bit more leverage...although I am not sure how wise that is as you do not want to strip the head right off...

Sorry I can't be of more help...

Or you can just take the easy road and stick a small hose into the fill plug opening down into the oil and suck the oil out (taste bad though, yuck).
