I go out today to some data runs and after a while I get a whiff of oil, no one else around so I pull over and investigate only to find oil pissing out of the aircleaner.  Seems some overflow through the breathers for some reason.

Was pulling around 6000 rpm when I noticed this.

Have done nearly 3000 km since I last changed the oil and have done 1 day of 1300 km with out a hint of this.

Could reving so high cause this to happen?? or is it something more sinister?

his what it was like when I got it home.....

 

hi, that don't look too-good , how long were you on 6,000 rpm for & in what gear , more info needed . doe's she still do it now when riding , off hand i would say its broken a piston ring if you ride hard like that & the top ring hasn't got clearance for extra heat expansion esp if the tune is not set-up proper too lean & or too much ign adv or both the ring will end butt & take the top of f the piston above the ring area off & score the bore , do a comp test or leak-down test ( engine hot ), but check 1st oil level o.k. oil pump not scaveging proper etc , cheers

Hopefully something simple.

Done it twice with me, but not that bad. All i did was clean the air filter and seemed to fix the problem...so i hope that was all it needed, but it seemed to work.

Well didn't get to the compression test today as need a different fitting for my tester.

Will be going for a ride tomorrow so will see how she goes and repeort back.

Geez Beeza, only 37mm there I prefer 105mm at least!!
Thanks for letting me know you have a gauge will keep it in mind if I run into any problems.

Before setting out on todays ride a quick check of the oil level reveals that the oil is about 12 mil down from the full mark whilst on the side stand, never topped it off.  So start her and no unusaul noises and the oil pressure ramps up to just over 32 which is normal and once warmed up properly it settles on 32.  In gear and of we go, plenty of power and no change from the last ride, all is good.  Did about 450 km for the day and no oil from the breather, although I never reved it out to more than  5,000 rpm and rarely go over that any way. All is good it seems.

I would say that Scottys diagnosis is correct.  Will still do compression test for peice of mind when I get to it.

As for the bidders, keep em coming and when you get up to about 30 grand I may consider accepting your bid.

Cheers for all the replys.

It all sounds a bit extreme Piggy........I doubt if we would ever get to anything like 6000rpm in general road use....damn near break the speed limit in every gear....Since I put me tacho on I was surprised at how low the revs generally stay..without lugging......last weekend at $1.80 chasing Crasher the revs got to about 4800 in sixth.....

The ECM starts to throw heaps of fuel in regardless when in WOT and max revs, unless set at higher revs ie. 10000rpm for tuning purposses. PEM (power enrichment mode usually set at about 4500rpm......

I have not ventured into the very high rev limits too often even when V tuning.....Leave that to Stix, FYO and Crasher

Bt

Yeah, have to agree with you BT I think I will be only doing tuning up to about 5,300 rpm because that seems to be my limit when getting it on before changing up, not much gain going above 5300 with this build when having a fang though the gears. In normal riding I generaly change at  or before 4,000 rpm.
