If it's a standard motor it will be a metal base gasket. If you need to replace the gasket, you'll need to obviouly take the head, cylinder, etc off.

Where exactly is the leak?

The base gasket is more of a shim to set the squish than a gasket.
The oil leak is likely to be the o-ring on the rear rhs at the base of the cylinder.
When you reassemble the cylinder, coat the base gasket in threebond (rtv sealant) and grease the o-ring well. You can clean the old base gasket up and re-use.
If the o-ring is fitted dry, as it is at the factory, it goes hard and ceases to seal properly...............hence your leak.
Not a difficult job. The hardest bit is getting the circlip back in the piston!!

its loosing quite a bit now this is after two days riding, but some flat-out on the motorway/autobahn

nelly ,
injection + exhaust system off, set the cams to timing marks ,remove belts , and judging by your last post leave the piston IN the barrel ;)
do i need the special tool for the head bolts?
and is 45 deg twist ok for the belts?



oh and if your free ill pay for your flight and beer if you come to my place and do it for me :lol:

nat, thats about it.................
Ideally you'll need the head nut spanner, but as ever there are ways around using "special" tools ;)
45 degree twist seems a little tight compared with the tension tool. I'd go for the 5mm deflection between the cam pulleys personally.
It makes life a lot easier if you can leave the piston in the barrel (especially if don't have a ring compressor), but if it comes out, take it off the rod, refit on the bench and refit to the rod when you put it back together. I have a ring compressor that works with piston on the rod, but it's fiddly. For the sake of a circlip it's not worth the fuss.
You won't need many parts. Head gasket, exhaust gasket, o-ring, piston circlip and some rtv.

as for "oh and if your free ill pay for your flight and beer if you come to my place and do it for me "....................... starnger things have happened :lol::o

well i started stripping the bike this morning and found loads of metal particles in the oil.......:mad:

isnt it always the case :flame:

and heres what i found ----

:o

I'm tipping 4.

Guys, chrome isnt magnetic so you wont get it sticking to the sump plug. Unless there are are huge chunks of metal on the plug what you appear to be seeing is totally normal and nothing to worry about.

Oh yeah, forgot about that. Thanks Paul.

I'll stick to computers shall I!
