OK Really stupid question for you XR Guru's. Can the decompression lever be used while the bike is running or is that really bad stuff for the valves.

Not that I would ever use it for a descent brake but I have always wondered. In the good old days we used to do things like that.

Decompression Lever

The decompressor pushes on the right exhaust valve rocker arm. Holding the arm open will stall the engine. Does not make for a very good brake.

OOPS, fixed. I did not mean decent brake, I meant descent brake. Kind of like a Jake brake. We used to use them all the time on the old 2 smokes for going down big hills but I have never done it on a 4 smoke as I just figured it would induce the valve into the piston.

But what do I know about mechanics?

those were the days....

My 3rd bike was a '69 Kawasaki C2 T120 Roadrunner, my first 2 stroke, and it had a compression release (and an expansion chamber - a mini orchestra!)

I had an old '73 CZ 400 with dual plugs and a compression release. Lots of holes in the head. God help you if it kicked back while trying to start it.

Has any one had this problem, or have an idea of how to fix it. I tried re-routing the cable, but I am still having problems...
I finally figured out how to route it so that it would not pinch the cable. I still don't like the placement for the decompression lever. Maybe one of these days I will get around to moving it. Anyone have any great placement ideas?

I just fitted an XR600 front end on my '83 xl600r, and in the post-swap debugging process, was wondering what that "best routing" for that cable is. Could you tell us about it, I'm missing my XL manual.

I also recently put my nice dual-carb head on the single carb XR600 engine I had been using. Runs like a champ now, lots of power.

The trick was that I had to run the cable behind the right side bolt of the gas tank. It runs behind the left fork tube, in front of the headstock, behind the right fork tube, and then behind the right bolt of the tank.

I hope that helps!

Thanks, The gas tank doesn't bolt in on mine, but I'll make sure it is the XL600 equivalent of that routing. Thanks.

Well I don't want to be left out here, I bought a 1986 XR600R, brand new in 1985. It has been my faithful companion since then. It has been extensively modified, so modified, that none of the 86 parts are even still on it. The last rebuild, used parts from a 1991 donor bike. As sad as it may seem, I have decided to part ways with the old girl, ever since the CRF450R followed me home, the XR doesn't get used. I thought I would keep it just for sentimental sake, but just do not have the room. Anyhow, heres a few pics of my old friend.
