This is a $10,000 motorcycle ladies and gentlemen, don't be a cheap ass and do it right. Get the right parts and seal it off correctly, then take the pair valve set-up stomp on it, beat it with a hammer for good measure and throw it away forever. It always amazes me that people come up with a great "cheap way to fix instead of doing it the proper way. Makes me laugh!
If your marbling it to fix until you can get the parts/time to do it right then fine, otherwise
First of all, you're not the boss of me or anyone else on this board.
Secondly, I think this fix was intended for people who either don't have the mechanical aptitude, money or patience to do the full PAIR-removal mod.
Fact is, it works. If you can't handle that, or that other people are "doing things" to "their" bikes which you don't like, oh well, never mind, get over it...
