Proper chain guide

Today I have finally fund some time to install a proper chain guide to my 640. Thanks to advrider.com inmates for pointing me in the right direction for the parts I needed for this.

Parts needed:
-54607066100 CHAIN GUIDE REAR ’94
-50207070044 RETAINING PLATE CHAIN GUIDE’94
-1 large M6 washer
-1 M6 nut

Note: On KTM 660 Rally they only use the chain guide without retaining plate

This is what we will be replacing

With this

Remove the 2 bolts that hold the old chain guide on the swingarm and be careful, there is a spacer back there.

That spacer will be replaced by the retaining plate front bolt hole.

The bad thing about this upgrade is that you have to take the chain apart. So if you are changing your chain, now it is a good time to add a proper chain guide if you wish.

Once the chain is threaded through the guide, you can start bolting everything back together. Tighten the front bolt just enough so that the whole thing doesn’t fall apart, now align the rear bolt for desired hight.

Now this is where I have been playing around and swapping parts. Since there is really small gap between the rear bolt and sprocket (5mm or 0,20 inch) I have used a collar nut from the front bolt to save on space, and used a new nut and washer on the front as there is more than enough space. Once both bolts are tightend (don’t forget to use Loctite) the thing is rock solid.

That is it. You are done. I feel this is a worthy upgrade to anyone that rides more off road.

Stay safe!

Bagging up

Today I have spent a few hours in the garage looking at where to mount a Kriega US-5 to carry my tool-kit or my medical pack. First I was looking at the rear fender.

Took a while to disassemble the rear of the bike, only to find out there is no space for the bolts. Looking at the above picture, two most left holes, didn’t have enough space below the fender for washer and a nut. So I reluctantly reassembled the back end together. Checking out the bike with a stuffed bag, I have found a nice spot, on the fairing just above the headlight. On a second thought, that fairing might not be strong enough to support the weight of my tool-kit over rough terrain.

So the only spot on the bike left, was the tank. The stuffed bag looked good on the tank, but I don’t have Kriega tank adapter, so I needed to figure something else out. Bottom strap was not a problem, just threaded it under the seat. Top was a bit more challenging. Straps wouldn’t fit around the frame tube, so I threaded them around radiator shrouds. I was quite happy with the position of the bag, but didn’t like all the straps hanging around. After a few more attempts, I was happy with the result.

There is enough room at the handlebars not to interfere with steering, or steering lock.

It sits nicely on the tank. And it won’t get in the way when standing like a standard tank bag.

That is it for now, field test will be done as soon as the weather improves.

Stay safe!
