1983 gs650gl air mixture screw o ring

[Guest]

Does anyone know the size of that tiny oring in which the air mixture screw seats on, on Bs32ss mikuni carbs ? Or the proper part number?

I was having an issue with #1 & #2 mixture screws , when I back them out or seat them idle does not change just on one and 2 .. after taking the carbs out to take a look .I see both are in pieces possibly from being seated to hard or just cuss there 31 yrs old .... so yeah I need four new ones !!
TO cycle salvage tells me to bring in one and hes sure he can match them up ... and an additional bonus he has the oem valve cover gasket stock for my 78gs1000e ...

If you are having issues with a couple of the o-rings in your carbs, the other 20 or so will be following suit right after.

Sounds like it's time to FULLY clean your carbs, then order up the full o-ring kit from cycleorings.com.

Yes, 30 year old rubber stuff tends to be brittle-oh look, it's Steve, now I can stop typing!
