    Spark plugs not sparking.

    Another member just had a similar issue, check your kickstand safety switch and relay. If either is bad they can prevent spark, but as already stated it's unlikely you would have power to the plug cables without spark. Unless the plugs are bad or the gap is VERY wrong. Also, when you pull the...

    1982 Maxim 400 NO SPARK PLZ HELP dohc

    :doh: I didn't even think of that. I even removed mine because my relay was faulty and prevented spark...totally forgot about that. In any case, happy to hear you fixed that issue and can start getting it running again! :thumbsup:

    1982 Maxim 400 NO SPARK PLZ HELP dohc

    Haha, yes drain the oil. Better safe than sorry;) When I first got my bike they had the D8EA plugs and that's what I originally replaced them with. Got it running like that without major issues. I now have the DR8ES-L plugs because I actually read the manual. I can't tell if it made a...

    1982 Maxim 400 NO SPARK PLZ HELP dohc

    Yes, pickup coil is on the left side. It's a bit of a stretch, but worth an easy shot. To check just remove the cover and see if they're dirty, off calibration or both.

    1982 Maxim 400 NO SPARK PLZ HELP dohc

    Poor bike, I hope you're able to bring him back. Throwing this out there; have you checked your ignition coils? Also, I'm just assuming it turns over and all that jazz, just no spark? Something odd i had with my bike is to check the pick-up coils. Mine were covered in iron filings and metal...

    Not staying alive

    Welcome to the forum fellow DOHC Maxim owner! These bikes are great to work on and learn from. Mine was my very first bike and I bought it "not running". The first time working on any part of the bike is a bit intimidating, but after you've done it once it'll be a cinch the next time (and...

    SR500 19" front wheel on XS400

    I ended up using the 500 axle with my 400 wheel. I had to buy different bearings to fit the axle in the wheel, but it rolls smooth without play. As far as the dual disc brakes being heavy I haven't noticed. You definitely have to be a bit more tender with them, but in the few test rides it's...

    SR500 19" front wheel on XS400

    I swapped out my forks for 500's so I could have dual disks.

    Can anybody tell me what this part is?!?!?

    I have the same bike/engine, but I can't figure it out either...and I don't really want to tear apart my engine to figure it out ;)

    Front Wheel

    You'll probably want to double-check the width of the rim and figure out if you need spacers or not.

    82 starting problem, wiring? Help!

    If it doesn't work with the proper wiring then I would start checking all the grounds like Jeff and Mike have stated. I had a bad ground in the rat's nest headlight wiring that stopped my bike from starting. Not sure if that was the main cause, but it my issue was gone after fixing that.

    82 starting problem, wiring? Help!

    From your picture it looks like you have the battery grounded to the solenoid. Take that one off the solenoid and ground it to the engine then try starting.

    Bolt missing?

    I just checked my engine and it has the same thing. No bolt goes there as far as i know. I've driven over 3000 miles with nothing wrong (until i decided to start customizing).
