Hi all,

I've had a slight oil leak from around the front sprocket area on my 96 750 for a while now and decided to change the gear selector rod oil seal yesterday but the oil leak is still there.

The oil is running onto the side stand when its up and there is always a drip under the black metal case which sits over the sprocket. Could it be the seal around the drive shaft behind the front sprocket which is leaking cos Im all out of ideas.

Is there anywhere else under that case it can be leaking from cos it seems that there is only 2 seals under there.

Thanks for any suggestions, its not a big leak but I dont want it suddenly getting bigger cos theres only one place it will end up and that aint good

Regards

are you sure its not from the airbox? there is that nipple on the LH side of the airbox that fills up and could be leaking down...

i dunno man that sucks...

Yeah,

what Joey said.

Also, check all the gaskets further up, head and valve cover. I had a hard to find leak that was drooling out around the same area your talking about. Ended up being both the valve and head gaskets. If there is any oil higher up, then its probably not from the sproket area (hopefully). Only way to check is undress her, degrease and check. Depending on how slow it is it may take a few days or weeks before its noticable.

Usually you can spot the leaking nipple on the airbox because your carbs are filthy/covered in shit. (were when mine and a friends did it)

The guys are right about checking other seals. I had a small leak which I though was also a seal around the gearshift lever, but actually turned out to be the alternator seal, and oil was making a path the the gearshift. Hard to see at the time because of the way all that crap is tightly packed in there..!!

Yeah definatly check the airbox, it has been hot as hell out here in Colorado and I noticed oil coming from the left side of my bike. After further inspection I realised I have not cleaned out the little nipple in a while and it was overflowing

Also go get some cleaner (dont use simple green) like PJ1 super clear, clean all the crap that has been building up and then see were it comes from...

You better hope and prey that it isnt the counter shaft seal or the clutch push rod seal... They are a bitch to replace since you have to split the case...

I've got the seal which sits behind the sprocket on order and I hope its not too bad to replace.

Can't see where it's coming from cos the rain wont stop here but I think if I change the seal and it's stil leaking Im getting a new bike

You might want to make sure that is the seal before you try to replace it...

You have to drop the motor and then start to split the case to get that one out.. It is a lot of work..

Oh christ, Ill not be doing that then John

I thought it would be like the gear selector rod seal to change, damn. Well hopefully it wont be that seal anyways.

Were is the nipple on the airbox? perhaps its that.

As soon as this damn rain stops Ill go have a good look.

<font size="2" face="Verdana, Arial">Ok lift your tank up.
Look on the riders right side of the airbox. There is a small condom looking deal with a clip around it. Just push the clip together with your fingers or some plyers and pull off the condom deal. I usually put a paper towl under it to catch any extra oil that might drip out of it. Dump out that oil, clean the inside of your airbox a bit and you are done

This is a bit blurry but on the left see that beige colored rubber thing sticking out? That is the nipple you need to pull off.
