    Tire Rubbing Chain

    So I'm about ready to ride this season. I set my x-ring chain tension (1 1/2" of play all the way up to all the way down) with my weight on the suspension. I set the rear alignment by using a straight edge from the rear tire to the front tire measuring the gap. I noticed that I rub the chain...

    What crazy stuff have you found in your oil?

    Recently I checked my oil pan that I use for draining all my vehicles and I found two copper washers and part of a piston ring. I wish my catcher was not so open so I had an idea of where/when they came out. I wanted to hear what stories you guys had. Pictures are great. Ps. Where do we even...

    Upgrades while engines apart

    So, Im starting to plan for my winter tear down and I've done some looking around getting ideas. This isnt my first engine rebuild but it will be my first xs650 rebuild. I was wondering what little xs650 upgrades I should do while I'm in there. I already know I would like to put Elephant feet in...

    Blew another regulator

    That was my second vr-115. They seem to be lasting me 2-3 months of little riding. The first one over charged my system. This one isn't letting my system charge. When I bypass the regulator connecting the green wire to power, I get 19v at rpm so obviously the reg is the issue but why are they...

    Trouble with Valve gap Changing

    Anyone have issues with their valve gap changing? I notice when i set my valve gap (cold of course), Ill set it to .003 & .006. Manually crank it around a few times to check. When I start riding the bike, it will sound nice and quiet. After I ride it a couple times, it always starts getting...

    Bike runs like crap after new mufflers

    I installed new glass-pack mufflers scrapping the stock system. Bike ran perfect before switching the mufflers. Vm34 carbs. Pilot jet #25, jet needle 3rd slot before muffler, 1 step richer now. Bike ran perfect for a test ride to work. Same afternoon it ran like crap for the way home. Sputters...

    Left cylinder misfire

    So I'm really trying to get my bike reliable and little issues continue to become present. I noticed while riding that I felt a miss. I could tell by the exhaust that its obviously the left side. I have a pamco with a new coil. New advancer. Mikuni vm34s. I replaced both vacuum lines going to...

    Overcharging my battery

    So I've been reading into it all day so I could give some helpful numbers to go off of. I'm using a vr-115. A few months old. I had it wired correctly o+y to brown. G to g. Black to ground. My system sits fine at idle but as soon as I rev it, charge jumps to 16.3v on the battery. I checked the...

    No spark after electrical advancer install

    This is getting frustrating. After installing the e advancer. I now have no spark. Power to coil initially is 12.4 volts on red and green wire. After first kick, coil voltage is 1.28. Battery still reads 12.4. What's going on?!:banghead:

    Stuck on the side of the highway.

    I was cruising just fine. About 45 mph. Then my bike starts doing some crazy bike firing. Now it won't start.

    Trying to kickstart my bike

    So Im finally getting to the point where I can attempt to start the bike and tune the carbs. Problem is I'm out there kicking and kicking and its not even hinting that it wants to turn over. Over the winter I rewired my bike to go kick only. I also installed mikes rectifier and a vr-115. I...

    What the heck is this? (Pictures)

    This small electric module is located right above the engine under the gas tank. I am going through my wiring harness and I noticed it was unplugged. My bike ran before I started taking it apart so I guess its not needed. Looks like 2 wires connect directly to it. Any ideas?

    Rectifier/Regulator

    So Ive been working on my 79 650xs trying to clean up all the wiring. Ive already got rid of what I could. I was planning on reusing me stock rectifier and regulator because they both work but I was looking through my parts box and I found a brand new regulator/rectifier unit. From what I...
