    650/X-2 First build

    It's 2021 and it has been a few years with the ski in the back of the garage collecting dust. I'm pretty sure I installed the "new" stator since my last post without any increase in spark strength. If I do get to work on this again the earliest will be this summer. Next steps are to 1) try to...

    650/X-2 newbie with a 650sx

    Keep at it. Mine is taking a similar amount of time and started off in similar shape. Almost there though...

    650/X-2 First build

    Thought I would update if anyone ever finds this thread. This project has dragged on for years and I still haven't had much luck. I've ridden the ski once or twice but it was low on power, hard to start, and running poorly. I've always thought it was a carb issue since spark and compression...

    Ski won't shut off

    I know it has been a couple years but I think I ended up pulling the start/stop switch apart and cleaning the contacts and that fixed the issue. So I must have been testing the switch improperly because that did end up being the problem.

    Ski won't shut off

    The switch does the opposite of what you said by the way. Low resistance until the switch is pressed and then it goes to a high resistance if I am remembering correctly. The ski also gets spark with the switch completely disconnected (switch circuit open). Should I try with the switch circuit...

    Ski won't shut off

    Ok thanks guys, I really appreciate the advice. The stop switch seems to test fine. How do I test the cdi?

    Ski won't shut off

    Hm, how do I do that?

    Ski won't shut off

    Also, I put in a new starter relay so maybe I didn't hook that up properly.

    Ski won't shut off

    I rebuilt a neglected 650sx from the ground up and finally have it running. My issue is that it won't shut off with the stop switch. Every time I shut it off I have to put my hand over the exhaust to choke it out. I tested the stop switch with a multimeter and it shows a high resistance when...

    650/X-2 First build

    Ok. I got the carb rebuilt and everything put together and ready to go. For the past week or so I thought I had an issue with the carb rebuild because I could get the ski started for a few seconds with a little fuel poured down the carb but otherwise there was nothing going in. In the end I...

    650/X-2 First build

    I think I may have figured out why the relay wouldn't work. The previous owner had cut the five wires going from the stator to the ebox. When I pulled the ebox out I disconnected these again. The relay is grounded at one of the posts of the voltage regulator but maybe this wasn't a good enough...

    I'm purchasing this solenoid off of Amazon right now (link below). Hopefully that will take care of this issue. Just got spooked when I saw these for $100+ on eBay and elsewhere...

    Everything iniside the ebox looks like it is in great shape too, no real corrosion on the parts or wires or connectors. I know the relay was working before I tore the ski apart a couple years ago and it worked for one click recently. I really don't know what happened.

    650/X-2 First build

    Also, to test battery cables I was just hooking them up to the positive battery terminal and then testing the voltage from the other end of the cable to the negative battery terminal. If there was no voltage drop I considered them to be good. I tried testing the resistance but that wasn't as...

    650/X-2 First build

    More on the electrical issue, need help: I bench tested the relay by hooking up the battery to the solder points and it did "work" in so far as it made a clicking noise. This was repeatable. I know that this doesn't necessarily mean that the relay was good but a quick summary of all the words...

    650/X-2 First build

    Some small updates: I'm still waiting on the carb rebuild kit and bilge pump bracket which should come in early next week. The bilge switch won't come in for a while so I will just disconnect it after each use if I get the ski going before then. Hopefully the switch will actually be waterproof...

    650/X-2 First build

    I agree, it was a great learning experience. I feel like I could answer a lot of questions that people may have about these and yet I have never even ridden a stand up. As for completion date, a lot of parts are coming in on Monday so I think I should have it ready in a week or two. Seeing...

    Haha, thanks. It has been a learning experience and a fun one. I just ordered a rebuild kit today for my 38mm Keihin CDK-II, a new Rule 500 bilge pump and bracket, some heat shrink tubing, a bunch of 3" cable clamps, and a waterproof toggle switch for the bilge. The bilge pump I had was...

    A few more. Sorry for the lack of temporal order on the images.
