Cleaning carbs
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?

Re: Cleaning carbs
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...

Re: Cleaning carbs
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 :)

Re: Cleaning carbs
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.FJD wrote:i would suggest to get them ultrasonic cleaned, that way you get all of the dirt out of it.
Conventional wisdom says to know your limits. To know your limits you need to find them first. Finding your limits generally involves getting in over your head and hoping you live long enough to benefit from the experience. That's the fun part.

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

Re: Cleaning carbs
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.thunderace wrote:I'm sick of saying this but Ultrasonic cleaning is a waste of time - it DOES NOT clean properly.FJD wrote:i would suggest to get them ultrasonic cleaned, that way you get all of the dirt out of it.
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....

Re: Cleaning carbs
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.

Re: Cleaning carbs
2 years? Just collecting dust then?
I'd be extremely obliged to come take that off your hands for a case of beer
