On my 2003 Ultra, if I was to replace the rear wheel belt sprocket and the belt looked fine, would you also replace the belt? Any pros and cons?
Thank you for any responces.

 

JUst based on mileage I would, imho belts are suspect after 100K..

 

In my experience, with bicycles, if you replace any sprocket, front or rear, replace the chain (belt) as they tend to wear together and may slip or wear more rapidly if only one is changed. So if you don't change the belt when you change the sprocket rapid wear may occur and you will need a new belt in a short time anyway. This may lead to rapid sprocket wear then a new sprocket and a new belt etc., etc., etc. Since the drive spocket is smaller and gets most wear, it would be best to change all of them: drive sprocket, belt, and rear sprocket.

 

Yup, I was kind of thinking along them lines also.
I guess I was just fishing

 

I guess that it's OK to go fishing. This isn't about bikes, but when the millrights at work change a sprocket, they also put a new chain on it. They said that it's easier to do it all at once than to do it in two separate trips. Saves time because it's already apart.

 

Heck, Markcuda, that is what we're all about in this forum: helping others. Fish away.

 

With the mileage you've got, I would replace the belt, and probably both sprockets. It's no fun breaking a belt on Sunday afternoon when you're 400 miles away from home. After 100,000 miles, that belt has to be tired, no matter how good it looks.

The miles Markcuda puts on a bike he would be changing every year lol.

 

When you have the inner and outer primary off, you should also change to chain adjuster, the starter jack shaft and take a good look at shifter linkages. Also make sure you have new locking bolt washers, Locktite 565 and all the gaskets and goo required before taking it apart. I would also check clutch, chain and inside sprockets. If you are going to powdercoat the inner primary while off, book it in advance.

 

after 100,000 I would think about a replacement
