    hey, question about Ignition coils, i bought a universal coil for my honda
    shadow, because the ancient coils on it were terrible, i noticed the new universal
    12 volt coils with 2 lead connectors have a shorter bracket post the the
    ignition coil body, so i was able to bolt down one side of the coils to the
    bracket on the dirt bike, does bolting down the coil have whatever thing to do
    with preparation or making the coils work properly?

    Here’s my problem, got a 92 fzr 600R, I was riding and the vr fuse blew,
    was told the vr its self is terrible and sending to much current, so I got it
    replaced, now the bike only starts with a jump from a jumper box but only
    runs on 2 cylinders, was running on all 4 when died though, it runs and
    rides except its like a 250cc, I was told my cdi is terrible and that’s why only
    2 cylinders fire, my email is jdmcarboy64@gmail.com thanks!

    Hey mrmax, fantastic vid. I have 1995 triumph speed triple 900 just fitted new
    engine. Early no probs, though 3rd header pipe staying cold on tickover
    until you rev it a bit. Take it out on the road and is fine for 100 yrds or
    so then starts cutting out suddenly then starts again after 30 seconds or
    so and then keeps doing the same. Swapped coils over same symptoms, same
    cylinder, changed plugs, any thoughts dude? just gonna check yer diagnostics
    site, cheers

    Thats ancient for a scooter battery. Start there, replace it and charge up the
    new one

    This one was full of resin too, some guys will meticulously melt it off on
    low heat to try to repair it if it goes south, but I didnt have the
    patience. Apparently the resin is a excellent thought for use on a bike that
    bounces up and down so much, but it does effectively make the CDI a
    substitution unit only

    Nah I dont reckon its your CDI, if your bike runs then it is sparking and
    your cdi is fine

    I just bought a 97 gsxr 750… Its been meeting for 2 years. Ive changed
    the plugs, oil, fuel, cleaned fuel tank and lines, new battery, and cleaned
    the heck outta the carburetors. The bike will run at idle but when I ride
    about a mile down the road the bike just shuts off and then about 15 to 20
    mins later ill be able to start it again. Some one please help?? Thanks

    Clogged jets, vacuum leaks, terrible air filter, or disconnected components of
    the intake system are the most common causes

    ignition coil and the positive into the plug doesn’t read whatever thing but the
    plug is new and the wire too, it could be the ignition coil?? and also mark
    4.0 when i test the ignition coil i have to replace that?? thanks

    For a healthy spark it should be stout and blue

    Nothing about clutch plates, but I do have several engine videos up, such
    as how to replace the head gasket, and how to replace timing belt

    If you can find one. Pretty much all bikes use their own CDI’s. What bike
    are you working on?
