    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Man am I a moron. I was cleaning some 34mm Mikunis in a solution called "greased lightning" and forgot to take the carbs out last night. When I got them out this morning all the electroplated brass (or whatever is coating the slides and needles) was kaput. The #$#$ ate the coating!!! I thought this stuff was a soap/detergent solution and that it would be safe for metals. Wrong!!!!!!!!

Does anyone know for sure........are the slides ruined?? Will the loss of that very tiny thin layer on the slides cause them not to respond to the vacuum??

Will I need to go ahead and put them on the bike to find out or am I wasting my time if I do this??

Iput required!

Never heard of that stuff. You also are NOT supposed to dip the slide assemblies in carb solution, as it destroys the rubber diaphram. When you dip your carbs in industrial carb cleaner you only supposed to leave them in for about 6 hours. I have a stock set of slides I will sell you if you need them.
 
Thanks, but these slides are from a set (2) carbs from a Yammy XS650. They are different from our GS Mikunis.

I would never leave the slides in carb cleaner but I thought this stuff was just a strong soap. Tough way to learn about soap.

Thanks for the offer.

The berryman's says 30 minutes, and I've been doing them for an hour. Is it safe to go the full 6 hours for the carb bodies?
 
Hi,

Aren't BS34 the ones that fits on 80-84 XS ? I thought the pre-80 were BS38 ..
Anyway, if your diaphragms are good and it is only a matter of the anodized coating I would sure put together the carbs and see if the piston-diaphragms move slowly ( raise them with your finger and see how slow they close ). If it works I would use them.. And maybe fog the engine before winter storage so the carbs slides won't rust .

I might have 2 BS38 laying around somewhere...

I went 24 hours on mine :)

I don't think it was Berryman's, but it was a bucket type carb dip. Maybe the one I got was weaker than Berrynam's proper.

I've have a Mukuni VM34 I forgot about for a year left in one of those dip cans. I pulled it out, installed a rebuild kit, mounted it on a CZ400 MX, and she started right up and ran great. I sold the bike with it on. Granted there were no rubber or plastic components involved, but the stuff sold now days is fairly weak and not prone to eat metals.

YMMV
