Now that I think about it the chain could be stretched and letting the timing "roam", hence the on again and off again noise. It sounds just like a loose rocker arm striking the valve stem...
Hey Walter, I'm curious...you have 90,000 miles on your XR. Have you replaced the Cam chain & sprockets on your engine? If so, at what mileage?

I think I'm going to start getting some parts together. The engine uses a little more oil then normal. I may pull the piston, hone the cylinder and slap some new rings on the piston while I have it apart. Next time it needs work I'll talk to CW.

Who was wondering awhile back how to change the timing on the XRL? This mod would do it! Interesting...

That's one of the mods some folks do to a Cummins to change the timing.

I also slotted the holes on my pulse generater to advance the ignition.

Yes, at about 55,000 miles. Then I replace the motor at about 70,000 miles.

I suggest you don't buy either the Emgo, or the Baja Designs copies. Make sure you purchase either the Ken Sean, or the Bikemaster mirrors. The Emgo mirror is less expensive, but it is inferior.

The Ken Sean mirrors are larger in diameter, and slightly convex. The Emgo mirrors are flat. Also, the screws which tighten the Emgo mirrors to the stem are threaded directly into plastic, and will loosen. The screws for the Ken Sean mirrors are tightened into a nut which is embedded in the plastic.

http://www.thumpertalk.com/topic/768...olding-mirror/

The Bikemaster mirrors are the exact same mirrors as the Ken Sean mirrors. However, the Ken Sean mirrors come with installation instructions, and the Bikemaster mirrors do not. If you get a better deal on the Bikemaster mirrors, here's a link to the installation instructions.

Did you advance your countersprocket also? Harder to do, but there is some serious midrange power to be had there. It's easiest if you just grind out the middle of the sprockie, degree it on the shaft and then weld it on. Little known secret.... I learned it from the PO of my bike. You heard it here first!
The hot set-up!

I have had good results with EBC clutch kits. Except one time the wrong, to short springs were in the kit. Opps.

I don't like giving up secrets, but hey, we're family. Have you tried putting a smaller front tire on these bikes? It makes them go faster. I didn't believe it until I looked on the speedometer.

Are you high?
There is no friggen way a delta of 4.65 deg. could produce the results you are describing.
Now if, and ONLY if, the TARSC ( total advance/retard setting change ) was 4.732 deg. NOW you would have something to brag about. Simply put 4.65 is insufficient.

My XRL always shifted stiff and notchy and was almost impossible to find neutral no matter how the cable was adjusted. It seemed a little better on fresh oil, but not much. The only way to find neutral was to blip the throttle while trying. Finally dropped in a $50 RMATV clutch kit and its like a new bike. Shifts smooth and slick and neutral is first time every time. Make sure to order and replace the o-ring for the oil pump to side cover fitting.

Usually the plates(steels) are warped too......best to do it all together.WITH SPRINGS..

Although its still snowing... off and on in Edmonton, I have gone for a few rides on my newly acquired XRL and it will need new tires soon. The current D606 seem to be ok, but I will do more road travel until I get to the BC area where I will head into woods. My 50/50 tire of choice is leaning towards the K60's. The PO of the bike switch the stock tires to the D606 and they lasted only 4500KM ( 5200km on it now )

So, my question: Has anyone purchased the Heidenau K60 in the stock form 120/90-18..... only to go "damn, should have bought the 140" ?. The price difference here is about $70.00 to go to the 140, which I do not mind spending. I see a few of you have done it with no mods required ( unless I skipped a post ).
