I did my doo yesterday, and switched to AMSoil, at 2700 miles on an '07. Changed out the oil filter (FRAM), too. I used a very tiny amount of blue RTV on the new gaskets. I started up to check the oil level, and when I shut down, the sight glass was full of foamy, light brown oil. It cleared over about 15 minutes to the right no-bubbles color. I started up a few times over the following 5 hours, and got the same result, maybe a little quicker clearing. When I started up this morning, I saw the same foamy oil in the sight glass. It cleared up in a few minutes, and I started up again. Same deal.
AMSoil says this is the result of using RTV sealant on the gaskets, adding oil before the RTV has completely cured, and not to drive the bike while the foaming is happening, but that once it clears for good it will not have any effect on the viscosity or other qualities of the oil.
Anybody have experience with this? I'm dyin' to ride! How long will it take, and should I change oil again? We're talkin' $$$ here with AMSoil...

All I can tell you is that my AMSOIL doesn't do that, so I'd have go by their answer as well.

You aren't talking that much oil so it's not like major $$ or something. However, draining and refilling may not get rid of the residue. If not, you definately waisted some money. What was their answer about changing the oil?

No bubbles, no troubles

On expert advice (but with some trepidation) I took the bike out and ran it up to operating temp and then put 40 miles on it, varying speeds. No more foaming, no bubbles, level is perfect. I'd gotten some other opinions over the net, but they all required more money and less riding: 1) I know I put exactly 84 oz (2.5L) in and changed the filter, so it wasn't overfilling. 2) And it couldn't have been the teeny hairlines of blue RTV inside the cases, as AMSoil suspected. 3) I doubt it was condensation, as the bike was at ambient indoor/outdoor tropical temp of 72- 78°. I doubt that you would see this foaming between AMSoil-only changes.
My guru said it was that the old oil needed a serious talking-to by the new oil, and that heating and circulating would do it. Evidently it worked, as the bike performed the best ever, smooth accel, less vibration, no probs. Except that I got some armor-all on the rear sneaker tread and experienced a heart-stopper when I got over that far in a nice right-hander. Something grabbed and all's well. The new doo got a final adjustment when I got back, too, so I'm good to go.:cool0012:
