XR 100 Automatic clutch

18 posts in this topic

Not trying to bash. But why would anyone want an auto clutch over a manual clutch? Just asking.

It is for my wife, and though she's fairly adept with the clutch, the pull is atrocious on the little XR 100. She does great with the TTR 125, but that bike is too tall for her in the woods.

I know what you mean about the clutch pull on the 100's. I changed my wifes handle and perch to a CR, but it really didn't help that much. The cable is like new, I guess they just didn't give them much leverage at the case. My 400 is like butter compared to her's.

It didn't help??? Mine is like night and day difference over the xr100 perch. They make CR80 perches with more leverage which makes it alot easier.

Don't bother with the cr80/85 clutch and perch. I have got two brand new ones sitting here for anyone that want to give me a few bucks (check ebay soon!).

There is an ealier post by a someone who gave good instructions on how to put a set screw into the existing clutch to pull the lever closer to the handlebar (adjusting the reach).

When you do this, it alters the dynamics of the clutch dramatically. Let me put it this way...

I was struggling trying to teach the proper operation of the clutch to my 9 and 11 year old daughters. I was unsure if they were bad students or if I was a bad teacher (probably more of the latter)

When I did this simple procedure ($20 and 20 mins) the clutch became very manageable for my 9 year old and she is shifting very well through 3 gears after only two hours. Short clutch reach helps in that it is much much easier to pull in and you can also remove all of the play so that the "friction zone" is almost immediate. Trust me, that helps.

On top of it, adjust your idle a little higher so that the bike isn't so prone to shut off.

Adjusting the reach closer makes it a lot easier to pull. Your grip and control will always be much stronger as you close your hand more. With your hand open and fingers extended open more, you have less strength.

The "friction zone" is usually set further out, where the strength of the left hand will be at its weakest point. That's why moving it closer is the best solution for small hands.

In this case it sounds as if the wife is rather petite. Afterall, the tt125 is a bit tall, indicating someone who is smaller.

With a smaller hand, you still have to adjust the reach closer. The cr80 perch and lever will not help much with that. I know this from personal experience.

This is the procedure I did. It worked perfectly.

Never ever take up all the freeplay in a clutch. It will cost you a expensive trip to the store to get clutch plates. Maybe try the moose easy pull, it is pretty involved to instal i believe. I think the cr perch is your best bet though. That set screw sounds like a easy way to burn it up though.

The cr80 perch worked awesome on my bike, although, I did put it on when I was installing my new bars that have a different bend.

You still allow some play. This fix limits the throw. It's like having a lot of play but the screw keeps the lever from returning all the way.
