    Running out of ideas on getting the Maxim to work ):

    Yeah so it's been a few months now and I've spent a considerable amount of time and money trying to get my 83' Maxim 400 on the road. I've spent maybe 10 minutes riding it and the rest of the time trying to repair things that go wrong (and this was a bike that was in good shape when I purchased...

    Tips on setting idle screw correctly?

    Just wondering if anyone has concrete steps for setting this screw? I've been twiddling with it a bit and can't get the correct setting it seems. Ideally, I'd want it to be set so the bike won't stall when idling but doesn't inch forward when idling either. Any tips for this?

    Few questions on idle and exhust collector...

    So I notice that even when I'm not giving the throttle any movement, the bike still moves forward a little bit. But when I lower the idle screw to the absolute bottom, the bike won't start as the butterfly valve is closed. Is there a way to strike a balance and have the bike start everytime but...

    Adjusting handlebars

    May seem like a silly question but does anyone know which nut adjusts the handlebar height? (circled in the photo) When moving the bike, accidentally lowered them and can't find the right screw for loosening them.

    1983 Yamaha Maxim Xs400 won't rev?

    My bike starts up fine but won't rev when I engage the throttle. I thought it might have been an oil issue but changed the oil today and there was still quite a bit left in the crankcase. Could this be a dirty carb issue? I also have very little gas left in the tank but the bike still starts...

    If a bike needs a severe oil change will it not rev?

    Pretty sure my Maxim 400 has no oil at all left in the crankcase and I'm going to change it tomorrow after I get the correct socket. Thing is, the bike starts fine now it won't rev as much. Is this because of the lack of oil? I also took out a spark plug to check it...could it be that the...

    Hey first time rider here and I'm getting my bike ready to use this summer. It's in very good shape, 60,000 miles on it, regular oil changes and just had a fork seal replaced. What kind of things could go wrong on an older bike when riding it daily? I've read about wiring issues before but...

    Rear brake light stuck on

    Hey just wondering if anyone has any advice for adjusting this? I know there is a small adjustment knob under the seat on the side of the bike but I turned it both ways and the light is still on. Does anyone have a photo of what the switch looks like in case I'm using the wrong one?
