Chucking oil out the back?

I'd second that, I've seen a guy blowing a smoke screen a WW2 destroyer would have been happy with and not suffering any lack of performance, it did use most of the gearbox oil to finish the race though

there's a shitload of roadbiking shit stirrers in offroad and i fear it's my fault for posting bullshit threads, i'm sorry. Frosty... take the advice that is obviously correct... that of the DIRTBIKE riding OGs

Yeh mate! I accept it can happen would have been funny to watch, but it would be most unlikely given Frosties Post.

What I posted was supposed to be informative and helpful (Its the way we are here) rather than the way Crapman takes everything. But we'll leave Crapman to his crapworld! I'm not going there!

The input shaft is on this side and the output shaft(with the drive sprocket on it) is on the other side with the gearbox in between. If the crank seals where leaking enough to let the little bath of oil in the clutch side into the cylinder you'd be loosing so much compression it prob wouldn't go.

Really?

Sounds to me like you barely understand the two stroke process.

Ok Frosty your choice now buddy check the carb etc as Danger and I suggest or go the crapman way do the crank seals.

I've just about had enough of KB for one day

Off to Def Leppard with my boy!!!!

I've blown a crank seal before and it generally will make the bike run like shit.

Question; will the state of the packing affect the jetting? In other words, is it worth having good clean packing in there when you do the jetting?

**tommorth** · 14th November 2008, 15:17

severly oiled packing could effectivly make the stinger longer and affect the jetting

crank seals can leak oil into the crankcase its not that uncommon xens bike did it not so longago
much easyer to clean swap the packing and check the carb/jetting first than change the crankseals especialy if you change them only to find it was the jetting afterwards

My Rm leaked oil into the crank, that was a Suzuki though... Fucking Shitzukis.

Anyway I'd check the packing first. My CR has quite a oily exhaust, but it runs fine. I'd not worry about it unless its running like shit.

FFS man - can you tell the difference between these two comments?

(a) "It's possible that the crankshaft seal is leaking" and......
(b) "Do the crank seals!"
