Title: Rear Tire, Fast Leak_options
Post by: goathands on January 26, 2011, 11:02:41 PM
Any advise would be appreciated.
My rear tire started to leak on my commute home this evening. It was near flat when I was able to pull off the highway. Luckily I was close to home.

I guess it wouldn't be the worst to Replace the Rear tire. It had started to square off and show some wear. It's the only mode of transport I have, and I wonder if its easier to pull the rear wheel off and get the tire replaced, or take the whole thing to garage and get both tires swapped out?

I fear I am about to miss out on another warm, dry weekend in CA.

Ahhh....

One option is BMWMOA membership ($40 in the U.S.) with their $26 "PLATINUM CYCLE CLUB MOTORCYCLE ROADSIDE ASSISTANCE (http://www.bmwmoa.org/club/membership/discounts_upgrades)".

Some motorcycle insurance plans come with similar options.  

I always remove the wheels and take them to the tire dealer when I have mine replaced.  I save a few dollars, and I don't have to worry about them messing up my bike.

I wouldn't replace the front tire as well, unless it is also worn.  I suppose if you are trying out some different model of tire you may wish to start with a matching set, but I only replace them as they wear.  I usually get many more miles from a front tire than from a rear.

I change my own tires now but before that I did like Rob.

Its not a big deal pulling the rear wheel off and a good opportunity to clean and check the crown wheel/brake shoes, i would just change or repair the rear wheel if the front is in good condition.

If you haven't removed the rear wheel before it's definitely something to practice at home in the garage rather than by the side of the road with a puncture.  Depending on the tire fitted it can be a tight squeeze past the brake shoes.  To make adequate clearance I remove the rear mudguard completely Another popular method is to remove the front wheel so that with the stand securely strapped down the bike can be tipped forward on its nose and the rear wheel dropped out. There are a few other methods. You may need to deflate the tire also whatever method is used.

I wouldn't trust a retail tire outlet to remove an airhead rear wheel unless they were familiar with it.

goathands, have you not removed the rear wheel since you got the bike?

You really NEED to (as do ALL new owners), to check the condition of the splines on the "crown wheel" (new term for me!), and to clean the splines on both the final drive and the wheel, and relube them with a good quality moly lube.

Ok technicaly its not a crown wheel as found in your average differential but better to call it that than a fingymerbob.

You may have a tube in your rear tire and it may be repairable or replaceable without replacing the tire.  Also I would check the valve to see if it is leaking. A little spit on the valve stem would tell you

No worries, Lou, I just thought it was a British term I had not heard of, before.

Actually, now that I looked it up, it is indeed a crown wheel.  (I'm not really much of a mechanic, and I haven't done a final drive rebuild, yet.)  It's mate is called a pinion gear, I believe.
