How To: Replacing the Shift Rubber the Easy Way.

And I recommend you use only genuine Yamaha replacement kick and shift rubbers. They're still available cheap and you won't find better. A note on the kick rubbers - there were two sizes used. The shaft for the rubber on the earlier bikes (up to around 1980) was 15mm in diameter. The later bikes had a smaller 13mm diameter shaft. There's a different rubber for each.
Yeah.... Partzilla still has 'em. From what I've heard, the repops don't last long.
In the shop old daze, we'd place the shift or kickstart rubber on the floor, standing up, pour a little gasoline onto the shaft and let it dribble into the rubber. Then, using the heel of your hand, shove the shaft down onto the rubber. Kinda like this:
But, that was boiler room "time is money" pressure tactic.
Your hot water method would be gentler on the rubber, maybe keep them from splitting, especially the questionable stuff...

Yeah... I've used the gas method too. Got the boiling water method from the Lycoming overhaul manual. The crankshaft front seal is one piece. You have to stretch it around the prop flange. Boil it, stretch it around..... I've seen 'em last 20yrs without splitting or cracking....
Yup - I have used boiling water a number of times and it always seems to work for me.
I wonder if that boiling water trick would work on our tiny carb o-rings...?
Hmmmm....good thought 2M.
One cannot overemphasize the importance of quality rubbers...
I was astonished how easy it is to fit and remove handgrips with compressed air when I was shown how.
Yup, you can have a whole lot of fun with some water, good rubbers and compressed air....
Don't forget the Wesson Oil

Another Old Biker Nut!
I use compressed air for removing and hair spray inside the grips for the new ones. The spray slides them on easy and acts as a glue when dry.
....and the hair spray can keep you looking smooth on those windy days!

Great thread, guys. Thanks much! If I owned any hairspray I'd try this last one. LOL. Boiling water and Wesson oil sounds like a combo I can deal with.

Isn't heating up old rubber to install/remove/replace part of Old bike restoration 101?
There are bikes (like my XJ650) that if you dont know to heat up the carb boots, you are going to have a really hard time removing/replacing carbs.
I may say that NOT knowing it is a right of passage that once you learn it (the hard way) you are initiated

Spent my life as a mechanic... and yeah, heat is mechanics 101. You have to remember though, most folk here didn't. Your average encyclopedia salesman (for instanceIsn't heating up old rubber to install/remove/replace part of Old bike restoration 101?
