Intake Rubber?
« on: October 27, 2020, 08:12:03 AM »
I think this one morphed into something far harder than rubber. Had to take the hacksaw to this one to remove too hard for knife!

That is the problem with USA units, every rubber part will be hard and brittle. Count up every rubber part and seal on the bike and you will be amazed how many  ;)

I think it's fair to say that's beyond this treatment...... https://www.youtube.com/watch?v=mtRAar1Ilfs&ab_channel=SPANNERRASH - has anyone tried this method, although I believe Ash has an effective one?
