    Rattle noise on idle

    Hi guys, when bike is cold or bit warm I can hear rattling noise on idle when clutch lever is not pulled in. When I pull clutch lever, noise goes off. Changed oil just to be sure but noise is still there. It happens on Vmax 1200 1996. Any reason to be concerned?

    Idle Adjustment

    Ok, I am new to the Vmax scene. I have recently bought my first and loving it. I have noticed that the bike seems to idle a little slow. So slow, it will sometimes stall, when stationary in traffic if you don't keep the rev's up. I have tried increasing the idle speed using the adjuster and it...

    COPS (Coli on Plug) in Australia

    Hi all, Just wondering if anyone in Australia offers the COPS setup for Gen1 Vmax? My 88 max has been playing up lately... the usual kicking, bucking, surging etc.. Did the shotgun and rode it 2 weeks ago, it was running the best it ever has - so much so that at approx. 125km/h decided to...

    Newby questions, poor idle, pops, won't run without choke

    Hey brain trust, Same symptoms I've seen MANY times on the boards: can't idle below 1500 rpm without stalling, abrupt loss of power, left sided pops and less engine noise. I refuse to go back to the dealership and lose $500 and three weeks of summer riding. I swapped out the plugs on...

    Fuel from needle jet at idle? WTH????

    Alright, I'm baffled. This is on a Venture with a Vmax Engine in it (at least from the cylinder block up it is). It's running pig rich at idle and low rpms. Will run a couple days and then cabon fouls the plugs. I tried to adjust the idle fuel screws and discovered that they had no effect if...

My question is, when I turn the idle screw out, does it richen, or lean out the mixture? What is a good baseline number of...

Sounds like a lifter tap. If any expiernced mechanics know what I'm talking about. It's a 97 max with 18,000...

    Idle Issues?

    A few days ago I was driving home on my vmax and I pulled in the clutch to coast and noticed the motor had completely cut off. I did this a few times noticing that the rpm wouldnt even stop at idle and would just completely turn off and not even hang at idle. When I got home I fiddled with the...

    Idle

    Hi everyone, I have a 98 vmax and it's my first ever vmax. I seem to have a problem and I am hoping someone may have a solution: my bike idles just under 1000 rpm and sounds nice. Problem is I have to give it a little gas in order to start it (unless it's warmed up). Also when the bike is idling...
