Engine no longer running...possible no spark?

    Hello All,

    I just want to apologize 'cause I'm sure the answer to this is in the forum somewhere, but I just couldn't find any answers (please forgive my noob-ness). Also, I think this site is great and am not sure what I'd do without it.

    Anyhoo, I've had my HT for about 3 months and have ridden it around 500 miles, having a blast with it. However, a couple of days ago I was taking a cruise down by the Mississippi River when it just quit on me.

    I've pulled the plug, cleaned it up, gapped it, and put it back, but I'm getting nothing. Since it does give a little putt-putt sound when I'm trying to pedal-start it, I'm assuming there's compression but maybe no spark?

    I think my next step is to find an NGK plug to replace the stock one, but I don't have much hope for that for some reason. I'm thinking the wiring might need to be replaced but am not sure...

    One thing I did do that day was to take it to the car wash to lightly spray away road dust and oil, but it was running fine on the way home and fine an hour or so later when I took it down by the river--however, I'm wondering if I got some moisture into the electrics...

    Any advice or leads to postings that would help would be much appreciated. Thanks all!

    I've got a feeling its the electrics on the engine side (magneto/coil), perhaps water has got into the magneto cover and damaged it that way.

    Thanks for the quick replies...I have yet to review all the posts about it and am hoping nothing's too serious.

    The magneto thing scares me because I wonder if maybe I did get some water in there by using the pressure washer. I try to be careful, but...

    I'll have to look into what I can do if it is the magneto. It might be a bit more complicated than what I'm used to repairing on the bike. Thanks again!

    If it has been sprayed with a jet wash it is almost certainly the case that the magneto has got wet and failed.

  6. I think particulate is your problem. Take apart your carb, pull out the brass pin holder, blow/poke out the gunk from your carb pin-seat and re-assemble. You are not getting fuel through your carb. Get an inline fuel filter so the particulate doesn't build up on your carb pin again.

    the brass thing with securing pin is not pictured here, but it keeps part #45 in place. you need to clear the gunk out of the area that #45 goes into.

    PRESSURE WASHER??!! Yeah I think that its almost definetely the problem, I only left my bike out in the rain for like 20 minutes and it got into the magneto. Just needs replacing, I've never experienced any electrical problems though, so dont buy one just because I suggested, but that does sound like the problem.

    HAHA! Yeah, yeah, yeah--I know it was stupid! I just wanted a nice shiny ride, ya know, and I didn't know...(but now I'd better!). I'm leaving a fan the magneto tonight. I'm sure that's probably it but maybe not--live and learn, I guess...;)

    Well, I left a fan on the magneto with the cover off overnight, but it still seems to be a no-go. I think this weekend I'll spend some time with it, but I'm afraid I'm going to have to get some new parts. I'm searching for parts on the net right now, but I haven't found anything yet...
  10. Just look at one of the vendors on this page to the left. They have the magnetos. I don't know what else you might need, maybe a gasket. they prob. have them also....
  11. check two wires that run magneto to CD. I use to ride myne in the snow all the time and in a 5 mile ride id have to stop like 5 times to mess with the wires. Sometimes they get wt and sometimes that causes them to oxidise and cause bad connect. Also make sure you are not grounding yourself out on anything

    While waiting for my magneto to arrive in the mail, I took sideshowsideswipe's advice to clean out the carby a bit since it probably needed it anyways. There wasn't any particulate clogging the pin, so I think I'm ok there.

    I also pulled the plug and checked for spark, grounding the plug to the engine, and there was none. Soooo, I've yet to get a good plug and toss the China one in the trash, but I'm still thinking it's the mag. If not, then maybe CDI or both... I'll keep y'all posted, and thanks again--I'm very grateful for this site!

    I walk by my MB everyday with a hangdog look on my face. :cry: I think the only one sadder is the bike! ;)

    Well, I guess it's only been a week since I ordered the magneto from dax. You guys are right--nice site... Any idea how long shipping from CO to MN takes...? (Just getting anxious to get back on the asphalt!)

    WOO HOO!!! I'm officially back on the road!

    Well, I got my magneto in the mail today from Dax, installed it in under 30 minutes, and she fired up on the very first try! :D I've officially got my perma-grin back and can enjoy riding around town inexpensively (filled up at the pump with my truck the other day--$40 gave me 1/2 a tank...:eek:).

    So thanks all for your patience and guidance. You all know how frustrating it can be when your MB's not running. I love this site!

    Ride on!
