dirty float bowls

Decided to get a clear glass and take a look at the gas in the float bowls, and found a good bit of crud.
trying to figure if I need to take the carbs off and go through them as I might have junk in the idle circuit, or just run some seafoam through it and see if it goes away... pretty newbish to bike carbs, but have rebuilt weber and dellortos before..
Thanks for any ideas, and if needed will go through the carbs starting this Sunday..( I work nights and weekends)

I would take off the carb tops (where the air pistons are). Then you can use carb spray cleaner to clean the carbs out pretty well on the bike.

White Plastic, with the orange/ yellow paper inside? Probably fine, just check your flow out of the petcock sans filter, then with and make sure it doesn't restrict. Also with Plastic filters make sure it is clear of Hot Metal, like the head.STUNTMAN STEVE wrote: I've got a few plastic ones lying around from my volkswagens, think they'll be fine?
Seafoam shouldn't hurt any, but will it do anything? Best to remove and clean, carbs, tank, petcock, then install lines and filter.

Aere there any rubber diaphrams/ gaskets I have to worry about? I might just take them off, just don't wanna mess up the sync...

When you take the carb tops off, be careful. The vacuum pistons have ruber diaphragms attached. Carefully inspect for holes or slits.STUNTMAN STEVE wrote:

I would like to try all options before pulling these things
probably faster to just pull them, those bowl screws are Phillips head and can be pretty tight. You need pressure pushing on the screwdriver to get them from rounding out. also very hard to be sure of the small transition circuits being clean, as with them still against the motor you can't see them.
But without a compressor, it will be hard to really clean them. Spray carb cleaner in a can has quite a bit of pressure though.

Yeah, I have special made screwdrivers for removing bowl screws on the bike. If not, it's probably not doable on the bike or at least it would be a major pain.Motor Head wrote:
