I have a problem with my 1982 Yamaha Max 400 intake boot. The rubber that seals the carburetor side of the intake boot is deformed. I am not sure how it happened with prior owners. Since any kind of vacuum leak is detrimental to the carb/boot seal, I need to find a solution for my restoration project. It is unlikely I’ll be able to find a replacement (it’s for the right hand side of the Mikuni carburetor.
Any resourceful bike guys that have run across this and found a solution?
For sure the rubber should be softened for both intakes to get the best seal, but is there a method/product to restore the rubber softness?
Apparently the plasticizers leach out of rubber over time. I’ve looked at a couple of videos that suggest wintergreen oil/alcohol mix 1:3 works.
Can anyone suggest the best method or even another supplier for the old right side boot?
