    Okay, I started my carb concern questions in the General Forum. Sorry. I'm moving them here now to stay on course. Anyway, I was wondering if spray carb cleaner is as bad for o-rings as the dip seems to be. I know I hit some of them with it, and I'm hoping I haven't totally screwed myself, but how do you do a thorough cleaning with spray cleaner and not hit something rubber?! It seems impossible.

    I wouldnt soak them in it but a little shouldnt hurt,keep away from the diaprams though,they are pretty sensitive ..also there is a differance in carb cleaners some will damage rubber faster and easyer then others

    I spray the carbs I clean with it and follow with air from my air compressor. That keeps the orings on the fuel passage tubes from sitting in the cleaner. Carb dip is bad because to clean the part it must be immersed in it for some time. It is not contact so much as it is the length of contact. So don't worry about using a spray cleaner like Berryman's B12. I recommend it. It takes some pressure to clear those small passages. The cleaner loosens it and the air clears it.

    Another quick save would be to flush the area around the o-ring with WD-40 to remove any residue and provide a little preservative.

    After Cleaning the Carbs with the spray cleaner ... I quickly treat the Throttle Shaft Seals to some Marvel Mystery Oil.

    I hold the rack Vertical and do the low side one and then flip the rack 180 and do the low side ones on that end.

    Then, I work the linkage to spread the Marvel in there. Makes for a nice smooth movement.

    And, everyone enjoys a nice smooth movement ... there, I beat you all to the gag.

    I wasn't sure about WD-40 either, but I figured it beats carb cleaner, so I did just that, and doused the rubber bits with it. I think I got enough of it in there to keep the peace. Does the same hold true of the diaphrams? I put a little Armoral on there, followed by a bit of WD, but I was unsure either way. Now I'm regretting putting both.

    You didn't hurt those Diaphragms treating them with the ArmorAll and WD-40.

    I do the ArmorAll when I do Carbs. I wipe both sides with a trio of soaked Q-Tips and leave it on.

    I also lay a thin coating of synthetic grease in the locating channel on the top of the Carbs to help position and keep the rubbers from shifting when I get ready to put the springs and tops on!

    Sweet. Looks like I'm good to go then. I think for my first time, I showed those carbs who's boss. Took me all weekend, so I sure didn't rush it. All I have to do now is order those two broken fuel jets from Chacal, along with a host of other stuff I plan on doing to the bike, and I'll have her up and running in no time.

    Oh yeah, also, about those idle adjustment screws. I set them all 2 1/2 turns out. Does this sound right, or should it be three?

    Thats about right for the 550.

    You can make adjustments when you get it running or start trying too.
