Clean carbs

Post by DevonCbx »

While I have the carbs apart, I noticed a fair bit of grime build up on the floats, etc. I was told to perhaps take the top and bottom parts off so I can clean the inside components up. I'm afraid to cause leaks etc. Is this a good idea.I would believe if I did that I may cause some more problems. Could I not spray cleaner such as brake cleaner or something into the carbs to clean them up? Or while the bike is running is there some type of cleaner to run through the carbs? I remember doing this years ago on auto carbs. Creates a lot of smoke but is supposed to clean them up? Thanks

I've heard of most using Yamaha carb cleaner but I'm not sure if its run thru the motor or just the carbs. Try the search function using 'carb cleaner'. The answer is in there I bet.

I think the Yamaha cleaner has to go through the carb only. Unfortunately it isn't available in Canada. I'm trying to get some through a friend who is going to the USA.

Devon, Mike Nixon is the carb guru here & I'm sure he will advise. Until then you will find very few (if any) "cleaner solvents in gasoline" that will do the job of a good disassembly & dunk in "Berrymans" carb cleaner. Spraying in the throat of a carb will only remove tarnish or gummy residue in the throat & inlet tract. To get to those hard calcified deposits in the float bowls, you need to be more aggressive....
For future carb hygiene you can't beat a top quality inline fuel filter, "Pingle" being the name of note....

You say the carbs are 'apart'. Do you mean they are just off the bike? If they are intact and pretty grimey, you can use a good quality brake cleaner to wash them off. It won't hurt the rubber parts. If you want to go further (are they working to your satisfaction and not leaking?), they will need completely disassembled and cleaned. If you are not up to that, you'd better get some help. They are such a pain to get off that I'd be sure they were clean before putting them back on. You can test them out by gassing them up on the bench and checking for leaks and checking to be sure the accelerator pump is working.
Mike Nixon's carb book is great if you want to tackle the job.
