Title: oily leak
Post by: grant71 on September 12, 2014, 04:46:18 PM

hello everybody. Today i  noticed an oily leak on no. 4 throttle body rubber just below the very bottom silver clamp. the clamp looks like a factory fitted item . Question is how does one remove these clamps and is a special tool required.  the oil is leaking out below the clamp. not much. just a droplet or two. any suggestions as to why there should be such a leak please

Johnny, Johnny, Johnny .... <sigh> :nono

Oil could be coming from the air plenum.  Crank case vents into the air plenum so oil accumulates over time.  Remove and Clean the air plenum.  Use side nippers to cut the Oeitker clamps off, not a plasma cutter.

I think I removed mine with regular wire cutters and small needlenose and twisting the f**k out of them. Eventually the oetiker binding will fail and you can pull them off. Lots of wrist work but fire-free.

Dremel tool, with fine grinding disk.  Quick work, no twisting.

As RBM also says, crankcase breather is connected to the plenum chamber at cyl. 4....and this would be
the oil comes from.
This would be a lot worse if the engine is overfilled.....didn't you have some problem with the sight glass ?

thanks for your replies. does nt seem like a serious problem . Or can it develop into a problem? seems like a lot of work to open up and clean out the chamber. i ll periodically use a degreaser to remove oil on the clamps. no need i suppose to remove the clamp. the rubbers dont seem damaged. at least the bike is not misfiring.Eric? what is a Dremel tool?

Johnny, a Dremel is far too underpowered to get the job done with those attachments. Go with a sawzall. Demos at f**kingmachines.com.

Warning...highly inappropriate content there...visit at your own discretion. It's what's commonly referred to as 'pr0n'...but I kid you not -- sawzall attachments. Of course I've never actually visited the site...but living in Seattle you exposed to all kinds of kinky weirdness.

Don't blame me...Johnny started it!
