As above really, my gsxr 250 carbs are a real mess, one screw that holds the needle value assembly in has rotted away, but my main issue is how do I remove the diaphragms? The sliders won't come out, I'm really stuck and covered in cleaning fluid, desperately trying not to get any on the rubber. Any ideas? Cheers folks
I have had a few stuck diaphragms \ slides, I usually just remove the top of the carby, carefully peel away the diaphragm from the carby body, then spray some WD or similar down near the slide. If they are really stuck, try removing the main jet and emulsion tube and that might help free the needle, then I gingerly push the slide up from the air box side of the carby until it comes free
Those carbs are most certainly in a bad way, in need of a can or two of threebond engine conditioner to clean them out. Wish you well my friend, you have a decent project ahead of you, good luck with it.
This stuff is good .... http://2fiftycc.com/index.php?threads/threebond-the-ultimate-cleaner.1229/ And this ..... http://2fiftycc.com/index.php?threads/ultrasonic-cleaning.1433/
Thanks phil, I have been advised to get the carbs cleaned 'ultrasonically' im a bit 'old school' and prefer to use traditional methods.
cheers grey import...I will certainly take a look, not heard of these products here in the UK, someone mentioned a calliper cleaning product as well, was it inox? or something like that.
Yes INOX products are excellent .... they are based on sheeps wool lanolin http://www.inoxmx.com/products/
I have seen some excellent results with ultrasonic cleaners, also some that were less than satisfactory therefore I'm sitting on the fence a little. Threebond has never let me down so far and you will find many members here on the forum who also have nothing but praise for it's quality. @GreyImport has posted up some links, peruse them and make up your own mind. Good luck!!
I will phil, thanks, I better get searching for goodies then All I get for threebond searches, is gasket sealer? no cleaning products..

Regards the ultrasonic carb cleaning, you can try Matt Harper at Harper's Ultrasonic http://www.harpers-ultrasonic.com/ Matt and I worked together to get the mid-body seals done for Keihin FCRs and he knows what he is doing. cheers
I suggest that while you have your carbs apart, and waiting to get cleaning and other things done, that you coat your diaphragms with silicone or rubber grease. If they dry out they can deteriorate very quickly.
3bond the crap out of them if u check my cbr thread on race bike mine look brand new from 2 cleanings
A dealer in old bikes & spares put me onto 'Subaru Upper Engine Cleaner' He dismissed the use of ultrasonic baths in preference to the cleaner. I was going to buy one & he talked me out of it. It works, god knows whats in it, smells pretty ordinary. Soak all the parts in it overnight & alls good $20 for a small aerosol can over here. The girl at Subaru said the factory mechanics use a can on each service.?? It's different to carby cleaner, it bought all the brass up golden & made the aluminium brighter. It's supposed to be better getting all the hidden little galleries & jets. Worked for me.
