Stiff boots!

yamaha vmaxQ: I own a Yamaha V-Max from the eighties and it was running a bit rough to say the least. So I decided to check things out and replace the spark plugs, air filter and give it a general clean. I have worked on the bike before so I have good idea on how things work and fit.

But when I took off the air box I noticed two of the rubbers that connect the air box to the carbs’ are stiff and well out of shape causing air leaks. I asked my Yamaha dealer to order new ones but they’re not sure if they can get anymore, and it will take forever if they can.

I’ve heard of different ways of ‘repairing’ them and wondered if you guys knew of anything about this issue, I understand they’re old parts and all of that?

A: We’ve seen this problem many times with old bikes because these items always become brittle and perish with old age. But there is one thing you can try.

Take the rubbers and soak them in thinners until they swell up to about ten times their normal size. It’s a bit scary to see but don’t be worried. Then take them out and leave them overnight and you’ll be surprised in the morning that they’re back to their normal size and soft and supple once more.

It’s certainly worth a try especially seeing as they’re hard to find, have a go you have nothing to lose seeing as they’re in such a state?

If any of you have the same ‘rubber’ problem on any sort of motorbike give it a try as well, no guarantee though folks.
