With 30+ years as a motorcycle mechanic I have rebuilt a ton of carburetors and the felt seals in Keihin carbs have frustrated me many times in the past. Since I could find no suitable solution to vacuum leakage caused by old, deteriorated seals I took it upon myself to create a solution. I took the original seal design and made my seal twice as thick and just a tiny bit smaller in the inner diameter so as to seal against the throttle shaft better. Since I started manufacturing my seals back in 2012 I have sent seals all over the world with great results.
