    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...

    rough idle and low rpm fixed

    I've been fighting with a rough idle for a long time and read all the posts about this on the forum. When the bike gets past the "normal" operating temp...close to the red but never overheating it would run rough and sometimes stall at lights and intersections...not good or safe! I received...

    Bike won't run without choke. Rough Idle

    Hello All, I am new to the site, and I love it so far. Everyone is very helpful. I am having a pretty serious problem with my 91 Vmax. I am assuming it is a fuel or air issue, or both. The bike will not start without the choke, cold or warm. It will idle, but only with the choke on. As...

    Going to be a rough day in court

    Here is an interesting article. Note the clocked speed in the RAIN! And people wonder why so many bikes are being dumped this year. Maybe he will get some money from the tire company for excellent high speed wet traction:punk:. Todd Motorcyclist clocked going 193 mph on NY highway...

    Terible rough or lumpy from 1500-2000 rpm. Please help video inside

    I'm not sure what is wrong with my vmax. I have adjusted the valves, cleaned the carbs, synced the carbs, new plugs and wires. It will idle just fine and runs above 2000RPM perfect. Now driving around town is just horrible because it wants to run so rough and lumpy from 1500-2000 rpm. Once past...

    OE Carbon Fiber tins - to paint, or trade for rough tins to paint

    Well, I pretty much knew from the get go that I would be doing paint on this bike at some point, and as I'm starting to line up what I want to do, I'm trying to decide if I should just use my OE carbon fiber tins, or if those are rare/special enough to bother trading them plus some cash for some...
