Pictures are located here.. I could not get them pasted into the post.

In those, I just noticed today while just dinging around, some rust color stuff that had leaked from between the manifold intake and the heads. I felt it and feels like "dried" oil. I am wondering what that means or if I just tighten the bolts up and away I go.

Thanks

You need new o-rings under those runners.

Your link didn't/wouldn't open. Thats OK. If the intakes o-rings are leaking, just remove all the intakes and install new o-rings. Easy job.

Yep! Like other forum members mentioned, intake o-rings.

Easy job, I did mine in 1h30m.

You can get some photos of the process here:

You remove the runners to replace the o-rings.  I did them one at a time.  You can do 3 at a time, one side then the other

If you have a local supplier, get a #123 O ring in viton. The original O rings are BUNA N which doesn't last.

'Everything' consists of the 2 intake retainers and loosening the clamps screws. Give it a little twist and it'll come right out. You just have to do it 6 times.

I looked at the video that someone posted. It is really really easy to do. I might do more and take off the tank and air to check out the tubes too. Thanks everyone!!

A lot of extra work for no gain. Keep in mind that old phrase....."if it ain't broke, don't fix it."

Just do the O rings as suggested, I usually will loosen the six bolts on the opposite side so you can lift the side you're working on just a tad. In doing so, I don't have to remove the intake runners. When you go to the opposite side, leave the first side slightly loose for the same reason. Just remember to snug(no torque wrench) all the bolts down when done.

I also replaced the rubber boots at the top between the carburetors and the runners.

Examine those for a consideration... save you some work "down the road".... cooldude

Yeah the rubber boots, I though about that. If I get one side off and can see the tubes, then I will just check them out that way. I bought this bike from someone 4 yrs ago with 147,000 miles on it. I have 162,000 now. I know that he kept it maintained, just don't know if we replaced the hoses sometime and what kinda of condition they are in.
