Yup,,sounds about right,,usually a 55 is right for most people,,keeps it arround 2-2.5 turns...what`s in yours ..or do you know..

mcma111 did me a great turn and did the Dave's mods for me while I watched in awe. 55-158. I think we left the screw at about 2.25. The new pipe did wonders for the running temp. I think I can bring it down a little lower with a richer mixture... the popping suggests it is currently lean (amongst other things).

You are correct about the l/h crank length,however ,installing an 600 rod on the L crank doesn't change the stroke.
I just worded it wrong-Must modify the L l/h crank half and mate it to the r/h 600 crank half. Or destroke the L crank.BUT the L crank is way heavier. As is the flywheel.(XRL flywheel weighs 8 lbs!).
To bring the flywheel weight down to 600 weight must remove added weight ring and machine .100" off the outside diameter.
I've done this to my L and it's a much more fun and a happier motor.

Well I'm keeping my fingers crossed on the oil issue...

on to more great news... I think my CDI just crapped out. Bike just stopped running. Idling good and, stop, cranks fine, won't start.

This is starting out to be a great season... Anyone have an extra working CDI I could put a deposit on to see if it cures it. I'll return it to you when I'm done. I'm just thinking this could be an easy way to check the cdi without buying a new one.

just a thought

after thought here... I better make sure it has enough gas it should.

Something else you could do is try to find the crankshaft from a mid '80s XL600LM, Paris-Dakar, or Pharaoh. They have an e-start system just like the 650L, but all the engine specs I find show that they have the XR600's 97x80mm bore x stroke, not the XL600R's 100x75. I don't know if the crank or flywheel is any lighter than the 650L's, though, and those XL variants were never sold in North America....and perhaps not even in the western hemisphere.

BTW, the 650L conrod is 132.25mm center-to-center and the XR600/XL600 rod is 134mm if anyone was wondering. I made a chart of those and other dims available below. Right click -> Save As:

http://img.photobucket.com/albums/v5...ns-printWM.jpg.

It looks like a link to the TT thread was posted some time ago, but here it is again. Big thanks to valverule and stepho over on TT for their help getting measurements. Pictures of the pistons are for visual aid only and do not represent the pin's actual proximity to the oil ring.

Please don't anyone embed the image in another post without hosting it on your own account somewhere. It will load every time that forum page/post accessed and take a big bite out my free Photobucket bandwidth. If my bandwidth allocation runs out, it kills access to all my linked images until the monthly "billing period" rolls over again. Thanks. If anyone has dims from other pistons, like the HRC XR600 slug, for example, I would like to add them to the chart.

Yeah, I have to work tomorrow, but I'll check it out one day. You mentioned beer, a buddy at work has got me interested in doing some brewing. He has made some really good stuff, he gave me some pumpkin ale last week.

That way you lose the steel tube and the box back there plus all of the plastic from the air filter to the carb. As for my side panels, well I got rid of those too. They're in my shed. I made some panels that use the original mounting screws and they have worked out great. I had to trim the panel side of the airbox to make it flush with the panel then install weather stripping to keep it water resistant, and again I have had no issues. I'd post a pic for you but I'm on my ship right now and posting pics just plain ain't possible, but tomorrow I can send you some if want. Just let me know.


-Barron
I'd like to see those pics of your side panels. Post em' here please.

Rear Fender and Tail Light Options

I'm looking for options to replace the stock rear fender and tail light assembly on my 2001 XR650L with a slick low profile setup. I'll need a place to mount the license plate also.

Any ideas? Pics?

Thanks.

I think the stock fender can still serve you well. See the following thread where I posted pics of my fabbed license plate bracket onto the stock fender after installing a WPS tail light. The plate bracket is very solid. My post is #574

RADAR69, please do tell what that rear rack is.
