Im currently stripping my carbs down just wondered if anyone had any advice on cleaning them. Or anything I should do while I have them stripped down etc? :grin:

i guess that depends on whether the bike was running ok prior to taking them off..
the carb overhaul/jetting thread (the sticky at the top of this section) is full of good info if you think you may need to alter anything...

well i would have a read of the carbs thread.
make sure everything is standard and correctly situated in the carbs when their stripped and thats your starting point. if i remember correctly (although i may be wrong) the emulsion tubes need to be in their correct carbs.. 2 have 4 holes, 2 have 5 holes.
the thread will guide you on this :)

one tip i read a lot of is when attempting to get the carbs back on... buy/use a set of RVF rubbers.. it makes refitting a lot easier :)

i would suggest to get them ultrasonic cleaned, that way you get all of the dirt out of it.
I have the equipment and do that frequently, but i guess there will be someone near you as well who can do the job.

I'm sick of saying this but Ultrasonic cleaning is a waste of time - it DOES NOT clean properly.

I've heard nothing but good stories about ultrasonic cleaning, what makes you disagree?

don´t know what your experiences are from, but in the last 5 years i probably had 25-30 motorcycles i bought/sold on again, and typically every 2nd to 3rd of them needed carbs cleaned out, which i did with my two cleaners.
The cleaning depends on the liquid you use, there is special stuff to do it, and it´s not cheap but very well worth the money.
btw: do you know of anything other to clean out all the small passages and bores in a carburator, other than sticking in stuff that does not belong there....

I have sat in my workshop a £3500 415v 3 phase heated U/S bath and about £200 worth of U/S fluid. I stopped using it 2 years ago. Even after three or four one hour cycles, fuel ways were still full of crud.

Nowadays I use a large parts bath. If carbs are really bad, I soak them in red diesel (cheaper than white) for 24 hours to dissolve the worst of the varnish. Then I bathe them in a proper parts washing solution. They always come out in pristine condition.

I do about 60 sets of carbs every year.

2 years? Just collecting dust then?

I'd be extremely obliged to come take that off your hands for a case of beer ;)
