1980 gs450l idle problem

[bubbarandi1]

hi
My bike runs great at speed but sputters while idling and sometimes stalls .The plugs are fairly new and the gas was stabilized over the winter. The valves are also within specs.. I don't think the Carb boots are leaking air,because it didn't rev up when I sprayed carb cleaner on them. Any ideas would be very welcome.

thanks bubbarandi

Clean the carbs and replace the O-rings with a kit from cycleorings.com

thanks nessism

I hate to tear the carbs down if it's something else. New gas did not fix it so maybe i'll run a can of seafoam through it and see if it improves .

Not to hijack this thread, but I just cleaned my 250T's carbs and it barely idles as well. My question is this: Are the carbs the same on the 450 as the 250? If so, it'll make finding a set of o-rings a lot easier. thanks.

i second the seafoam suggestion, i had a similar problem with my 450 and i didn't feel like taking off the carbs for a 3rd time. all i did was run seafoam with the gas just like the bottle recommends i went for a more concentrated mixture then i would run the motorcycle just fast enough that it wouldn't die. after a few days of this it evened out.


and if a mod could look at my account for some reason i cant start a new post.
