Release the Kraken!!!
Need help guys. Trying to do a full rebuild on my carbs, but cant find the throttle shaft seals. Any ideas?
They’re not suppose to be replaceable. I’ve never broken down a set of CV carbs far enough to warrant new seals when cleaning a set. Just my $0.02.Need help guys. Trying to do a full rebuild on my carbs, but cant find the throttle shaft seals. Any ideas?
I guess I should have phrased it differently. They are removable but Kawasaki didn’t intend them to replaced which is why they don’t show on a parts diagram…along with the throttle shafts and butterflies.Doug, they are replaceable, 100%. Ive not replaced them, but I have had carburetors torn down for a deep clean, seals are replaceable.
I've never torn down carbs to this extent either. Worst case scenario, you might need a set of bare carbs to build upon and salvage what you can off of your set.Blaine
This is what I have learned after 30ish years of riding and turning wrenches - most riders wouldnt even bother with an issue like mine since its not critical and the bike runs fine otherwise. Im sure your 70,000 mile bike runs like a Swiss watch, happy for you. I've isolated a vacuum leak at the carburetors, specifically the throttle plates. Appreciate the link for the o-ring kit. But the seals I need are called, I believe, D-rings. O-rings would bind the throttle shaft. Re-jetting the carbs wont fix a vacuum leak.
The seals are made of rubber. Over time the rubber gets hard and cracks, just like the intake boots and vacuum hoses. Normal wear and tear.What would cause such an uncommon leak? Corrosion? Damage? Age? Factory flaw?
What is the material made of? I am asking out of curiosity and future reference.
Since it's a 40mm Keihin, you might search for other bikes that have that carb, like Harleys.
I don't know what this is?

If you get the old seals out, pictures and measurements might help locate a set?
Allowing rubber to soak for at least 24 hours in a solution of three parts isopropyl alcohol and one part methyl salicylate, will soften them upThe seals are made of rubber. Over time the rubber gets hard and cracks, just like the intake boots and vacuum hoses. Normal wear and tear.
