I've never heard of the water injection system. I think that's more than what I'm wanting to do right now. I just wanted to use a decent fuel system cleaner. Also, I don't have the PC3 with ignition control. Thanks for the advice though!

 

Pretty much anything you add to the gas is a scam. I guess you could use sea-foam, that's the only stuff that works in my opinion. I don't suggest it on old motors (which the bike isn't). I had an engine (car) I used sea-foam on and the HG blew within a week. It was a used motor and it broke all the carbon free that was clogging the leak. You can add it to the gas, but the best way is to feed it into the engine through a vacuum line. This would be difficult on the 929 because you'd have to hook a line up to all 4 throttle bodies between the butterflys and head, then draw it in all 4 at once. I guess you could clean 1 cylinder a day during the week.
