Thought this might be useful for anyone with a flying brick.....
Riding back from Whitby on the last hour of a 4 hour round trip I was getting a strong smell of "burning oil" from the bike
After I had cleaned the bike I decided to try and find out what the problem was
Very quickly I discovered that the rear crankcase breather hose from the engine to the airbox had a small split in it and there was evidence of oil residue in the area around it
To get to it involved removing the petrol tank , side panels , crash bars , inner fairings trim panels , lower LH & RH fairing sections , radiator cowel , air filter , upper and lower air filter box sections
The crankcase breather hose itself attaches to a spigot on the engine with a jubilee clip , passes through an access hole on the side of the airbox and then fastens inside the airbox with an Oetiker clamp
One removed the hose didn't just have the small split I had originally seen but was almost completely detached at the ninety degree bend where is attaches to the engine spigot
I also noticed some oil misting on the throttle body vacum pipe and although it was not split the rubber had hardened and shrunk to the point where the clamps that hold it onto each of the throttle bodies were all loose and the pipe could be easily pulled off
So a new crankcase breather hose needs to go on order and I will fit a new throttle body vacum pipe which I already have
Whilst I was in there I renewed all of the fuel injector O rings and also gave the front engine casings a good clean and fitted stainless steel bolts , the paintwork was in remarkably good condition for a 22 year old bike !
