Removing engine cover for fixing oil leak Yamaha R1 (2001)

[aetius]

Hi,

I've got a slow oil leak on my R1 right hand side, it's coming from the black engine cover (as shown in the pic). I've removed all the alan key bolts from around the cover (the three shown in the pic were just put in place to hold the cover back in place temporarily), but still can't remove the cover.

I noticed 3 small lips at the back of cover, which I can pull on and slightly move the cover, but it doesn't come off completely. I wanted to remove the cover, replace the seal and add some gasket/oil sealant all around.

I'm having trouble removing the cover, can anyone advise how to do this? Despite all the Alan bolts being removed, the cover only moves slightly and is stubborn to remove.

Failing to remove the cover, I may just add sealant all the way around the cover - would this be adequate?

Any advice is much appreciated.

Slacken/unhook the clutch cable and try again. Don't put sealant on it, buy a proper gasket it will only cost £5-10.

As above. Unhook the cable, take out the dipstick and give the casing a few good knocks with a rubber mallet. Be aware that it may be being held in position by metal dowels so might not just drop off how you're expecting it to. You might also be able to prise it apart with a screwdriver but make sure you don't damage the mating surfaces.
