    A good friend of mine who lives in the UK may be able to help, and is a good guy to know in any case.

    He's got an online motorcycle parts business:

    Imma do it then. The ideal thing would be to buy a spare rear rim and put an aggressive knobby on it with a 49 tooth sprocket to go with the 13t :evil

    If you go too far with the gearing you will make first gear useless.

    I'm trying to get more use out of 2nd and 3rd gear in the tight stuff. I just bought a 13t sunstar sprocket on ebay for $13 shipped

    I'm trying to get a set of fork springs from Race Tech but apparently they don't have any info on the XL600R front fork. I'm wondering if anyone has a stock spring just rolling around that could get some measurement off of it. Otherwise no big deal, I'll just have to wait until I tear my front end down.

    I have the stock ones from my hybrid bike in storage. I could pull one apart this weekend and measure it for you.

    Hey all, just bought an xl600r and have been doing a ton of research on refining the suspension.

    Here is what I have come up with, please chime in with corrections/help

    XR600 forks pre 93 so I can still use stock wheel bearings-speedo drive etc. 15mm axle, but 91 and 92 are best?

    Get XRL triples- does xrl stem work in xl neck?

    XR600 rear shock of same vintage- rebuild-re spring

    Stock swing arm to retain cush drive

    How much will this raise the height of the bike? I kind of like the stock height, but an inch or 2 wouldn't be bad.

    You can use later 17mm axle forks if you change the bearings to 6003's. You will need the larger speedo drive and bearing spacer too. Not hard or expensive to do. I put XR400 forks on mine and converted the stock XL wheel to 17mm.

    FYI, I'd heard that the XR600 rear shock raised ride height, but, the one I bought recently to level out with my forks is the same length as the XL one.

    What did you use for a rear shock?

    How much did the xr400 forks change the ride height if any?

    Thanks

    I didn't measure before and after height change, but I figure it was an inch at least. I put an 88 XR shock on the rear and longer swingarm and wheel from an XR too. The XR shock is about 1/2 inch longer , I just measured my old one against my spare XR shock (14 1/2 and 15 respectively). The XR 400 forks are roughly 36 inches from axle center line to the top of the tube, and my XL forks measure 35 1/4 inches. I am running the 400 forks 4 notches down which brings the length from axle center to the top of the fork crown about 35 1/2 inches. My static seat height is roughly 36 1/2 inches now. I know it is taller by feel, and the fact that I had to get a longer (XR) kickstand.

    I hope this helps your planning, if you need any more measurements let me know.

    P.S. I am running .45 kg front springs 7.5 weight oil, and 11.5 kg rear, 5 weight oil 175 lbs. nitrogen. I bulk out at 200 lbs. most days.

    Don't go out of your way to do it. I can just measure mine once it's apart. I just don't like letting things lay in pieces while I wait for parts. That's when jobs tend to get botched.

    What measurements do you need? I have my old fork set leaning in the corner.

    I hate phillips head screws for just that reason. I replaced mine with a flat stainless socket head screw. I forgot what size, wanna say an M4x8 or something small like that. Go to your local hardware store and get something like this.

    My email states that I need spring free length, OD from both ends, and travel.

    I don't really know how you measure travel. Maybe they're talking about fork travel. Or are you supposed to try and compress the spring and measure it again. Wouldn't want to try that lol.

    OK, here it is. The spring is progressive wound with tighter coils on one end and it tapers down in diameter for about the last 4 coils or so. Small end ID 19.6, OD 29.2. Big end ID 29.23 OD 32.7. Overall length 22 3/8 inches. Additionally there was a spacer on top of the spring 2 3/4 inch in length and a washer between them 1.5 mm thick. coil cross section 4.78 diameter, 62 coils. Travel I don't know exactly, no way to measure, but I would use advertised wheel travel for that. The manual doesn't give travel specs.

    I didn't buy the bike new so I don't know if previous owner changed springs in the forks before me, but I suspect not. 87 XL600 forks.

    Thanks for the info I wouldn't mind it sitting a scooch higher.

    I just bought a set of xr400 forks,triples,axle on ebay with .46 springs and gold valves. should work out good.
    Did you use xr triples or xrl?
    I have a set of DR650 triples laying around that are 43mm have the key hole and rubber mount for the handle bars. I may see how those work as the od on the bearings are the same.
    I assume you used an xr650l speedo drive?

    I will probably have more questions
    Thanks for the help so far:D

    I used the XR triples because they came with the forks. XRL makes ignition switch mounting easier. Maybe gauge mounting too.

    I used the XRL/XR400 speedo drive to fit the axle. I was contemplating just drilling the 15 out, but couldn't figure a good way to do it and still have all my fingers too. Seems I had to change the cable too, it was too short. I think I used XRR, or an XRL cable.
