    By any chance do you have the cam gear 180' out or upside down? Where is the mark TDC??

    I have an 86 in really good shape, been riding regularly, in between the extreme cold. The regulator went bad and cooked my battery, now I am sidelined and need to get back on two wheels. Thanks for looking around. Andy

    The TDC mark is dead-on. I actually set up a little jig with a machine vise holding a ratchet/socket to ensure the mark is exactly lined up, which wasn't that easy.

    And no, the cam sprocket is not 180º off... I used a paint-pen during disassembly to help me put it back together in the same way.

    So all that being said... do you agree that a new cam chain is called for? Seems wise to do, now that the engine is on the workbench. Plus, the bike shows 28,XXX on the odometer, and although someone has been in the engine in the past to freshen some things up, there's no way to know if they paid any attention to the cam chain. For all I know the chain could have 28,000 miles on it.....

    After thinking about it a bit, though... it seems you are suggesting that it might make a difference if the cam sprocket is off by 180º.... (which seems to me hard to believe... I would think that the imaginary line through the two mounting bolt holes would be exactly perpendicular to the two witness marks...)

    But the PO may well have put the sprocket in 180º off... so if it is the case that is might make a difference, I could certainly try rotating it and checking again....

    IIRC the sprocket should have three marks on it. 9 o'clock, noon/TDC and 3 o'clock. I don't see the 12 o'clock mark in your picture.

    This is from my XR650l but you should have the same markings.

    If you can't get the 9 and 3 o'clock marks to line up with the edge of the head that is the tell tale sign that the chain has stretched.

    I'm a dumbass?? :lol3 He asked for a suggestion, I gave it to him. He said he was cheap, fucker. If he didn'tsay he was cheap, I wouldn't have suggested my POS cheap chain. Sometimes when you're in a pinch and you wanna keep on riding, you gotta buy a temporary cheap part until you can get a good part with a reputation. And sometimes, you can buy something cheap and it be as good as anything else.

    I had the mechanic at my local shop install it. I walked in looking to buy a regular master-link but they don't carry them, just the plates and rivets. So they had me bring the bike down and they installed the chain for me.

    I think a regular masterlink would be fine, just less chance of mechanical disconnect with the riveted link :D

    You said "If you never heard of it before other than some dumbasses sugestion , then dont buy it"

    I was the only 'dumbass' with a suggestion. :D How specific do you need to be? Get back to fixing your damned air conditioners. (I'm just mad cuz I don't have one:norton)

    Those chain tools are a lil pricey themselves, just a heads up.

    Hello all. I have been following the thread for awhile and figured I might as well say hi. I scooped up this 85 XL600R a few months ago, tore it part way down, put it back together, and rode it. What a ridiculously fun motorcycle :clap. Now I think I'm hearing the timing chain noise, so that is the next thing to address. Ah well, wrenching on the beastie is kind of fun. Anyway, here is my bike.

    my head lights went out as soon as I got off the marine base after work :puke1

    The light started to dim as revs increased and then it just cut out. I tried to switch to the hi-beams but nothing except the blue light came one.

    wtf guys? I had a head light problem before, I cleaned all the contacts and changed all the connectors. It worked after I did that for like a week and then this happens :mad?

    Check your stator output for the lighting circuit, then voltage rectifier and regulator...
    I'm thinking one of these may have died.......:cry:eek1

    To come back on the Cam chain subject, I always use to buy the cam chain at Honda, in europe the price is around 75 euros, but I've ordered a Wiseco Cam chain for the first time, any feedback on these?
    Are they reliable as the genuine?

    Thanks

    How do I test? volt meter?

    Good god I hope it'snot my stator, too much $$$ right now :cry

    Yep, voltmeter, should be AC volts before the rectifier, DC after.

    Looking for advice on an 1984 XR600 that is for sale in my area - North Metro Atlanta. 14,000+ miles. Starts up easy and the engine feels very strong and tight. Idles perfectly also. Looks pretty much stock. Stock exhaust etc. Drips a drop or so of oil each night - not sure from where - maybe countershaft seal? Talking to 2nd owner. He bought it with 10,000 miles and put 4,000 on it himself. He's not sure if the engine has ever been rebuilt.

    Without going back and rereading this entire thread, would you mind telling me common issues with a bike like this. Do you have concerns about the mileage? He paid $1400 for it and would take somewhere in that ballpark - maybe less I think?

    Thanks for any advice.

    Looks kind of like this one. Not actual bike:

    Not really much goes wrong with these bikes. The stator would be the main issue (mainly age related), replace with a ricky stator when necessary.
    The other thing to watch out for is the carbys. Make sure that they are clean, and possibly drain the fuel if it is not going to be used for a long time.
    14000 miles isn't much, there are a lot of bikes on here with at least double that, and still going strong. Change the oil regularly as these bikes do not have an oil cooler apart from the frame.


    buy it and enjoy...:D

    Very good advice on the other reply. I would just like to add that, yes, the shaft seals may become leaky, and so you might want to get all the shaft seals and replace. All except the decompressor shaft on the head cover can be done without taking any engine cases off. You just have to gently pry the seals out being careful not to scratch the shafts themselves. The shifter shaft leaks sometimes too. Then there is the kickstarter shaft. If you need to replace a leaking decompressor shaft, it requires removing the engine because the XL600 can't have the head cover removed while the engine is still in the frame, unfortunately. If only they had made that a splined shaft with an attaching lever, then we could be leak free very easily. +1 on the ricky stator. Great product, great warranty.

    gonna test the electricial components tomorrow. if the stator is bad I will have to sell the bike since i cannot afford a new one. :cry

    anybody want a XL600 with a fresh engine??
