Ais

AIS is Air Injection System. They inject a little air into the exhaust to burn off gas. When you change exhaust you get a little more popping. Some popping may be always there. It would be illegal for the dealer to change it.

Here is another source of info, no kit required. They move hoses and install marbles. I have also seen a kit on E Bay.

I removed the lines pump and all associated hardware. Pulled the elbows from the heads and filled the holes with a plug kit from the internet. I just like my bike cleaner and leaner. Plugging the lines can lead to the lines rusting inside to out.

That's the site that I'd recommend to any newbies here that own a 650.....great folks there, and can help you with all kinds of mods. That's the one thing I miss moving up to the 950--I don't have as much reason to post there.

I can tell you that when I sold the bike last month those plugs were still sealed into the engine. I dunno why no one is telling you to do that now. I'd do it though.
not to change the subject but what's your honest opinion on the Clevver you have installed....does the damn thing actually work?
