I also had some sealing glue on the front mating surface of the sprocket cover. It is only for preventing chain oil "leaking" out to the front I reckon.

Yes that is it but most people do not refit without any probs although you might have to adjust the clutch to compensate even for that tiny distance

The gasket seems quite expensive for what it is tho. Pretty sure it's around £25. I've always wondered how necessary it is to replace it.

if its to stop oil leaking out i will apply a thin coat of something to the surface of the cover when i re-assemble i think....

No one seems to know what the gasket is for- it can't be there to stop any fluids leaking out as there's a big hole on the right of it for the chain!

It do stops leaking chain oil to the front. What else could be its function?

If anyone else has done this, when you re-assembled things, did you have to adjust your clutch lever?

When i pull the clutch fully in, there is still drive to the back wheel, when its on the center stand and i put it in first with the clutch in, the wheel has positive drive, extremely weak but its there....

Assuming adjusting the cables will solve?

Should really be adjusted from the bottom end first then the lever end.

fazersharp · « **Reply #37 on:** 21 March 2015, 08:29:38 pm »

That phah nom eh nom (help please) is normal when on the stand, but in theory if you had a gasket and removed you may have to adjust the clutch, when you look at how the mechanism works, that long leaver travel only translates into a very small push on the clutch push rodd to operate the clutch and so a very slight change in distance caused by removing the gasket could make a difference

I wouldn't spend too long trying to eliminate that. As long as the drive is only very weak, as you say it is, that's pretty normal & to be expected on wet sump bikes. It's an effect where the oil between the clutch plates creates drag.

Thanks all, i think its normal based on the comments, and there are no other issues

Gasket could be there to aid the tightening of the bolts. Allowing some sort of compression between the two metal edges

That's a sports gasket. Makes the bike go faster. I've three of them on mine. Had four on it but I couldn't keep the front wheel down so I had to take one off

With that many gaskets whatever you do don't add a power band as well, you might flip the thing!

OK, 170 miles later and its running sweet

- looking for a replacement gasket anyway, anyone improvised with their own gasket?

Yamaha dealer did mine Free of Charge 2 years ago on an 11 year old bike! Worth asking
