Hi all

Picked up a 99 RSV this fall and didn’t get to ride it much before the riding season ended. I keep it in a work shop heated at 50* and noticed it was leaking oil. It seemed that it was coming from the rear, left cylinder cover.

Called the previous owner who I know and he stopped by and found the Allen bolts on the cylinder covers were loose. We wiped everything down under the seat and I checked it some time later and it was still leaking. Not a lot of oil but I don’t like leaks.

Looks like it’s a $33 gasket and not too terrible of a job. Especially with the previous owner to help over some pizza.

Any thoughts or advice is appreciated.

Thanks

If it is a valve cover gasket, very easy repair and no worries after the repair is done. I'd say someone reused a gasket after checking valves. No big deal reusing as it is usually fine and an easy fix if it leaks.

Ok besides the gasket, might as well do the carb boots too I suppose. Previous owner included another set since the current ones are cracking. They aren’t leaking...yet. Any other parts or gaskets since I’m tearing down that far?

If you have replacement boots you can help settle this common issue

I have never pulled them off myself, but I understand there are two layers to the boots, the inside is an aluminum tube, that can not leak unless it is compromised. The outer layer is a rubbery plastic that cracks with age, but it has no role in sealing the boots.

Please take a look at your new ones and see if you can confirm this. You can usually identify aluminum because it will feel cool when you first touch it (it pulls the heat out of your finger for a second).

Many people see the cracks on the boots, freak out, and replace them - but the consensus is the black plastic is purely cosmetic.

When I bought the bike, I looked into this and I believe I found the inner metal sleeve is only partial. Let me see if I can find the photo of the guy that cut them in half

interesting photo

it would take a really deep crack thru the plastic to create a vaccum leak

the typical surface crackling wouldnt go all the way thru

If you pull yours off let use know what it looks like on the inside surface.
