    Intermittent 3 cylinder running

    I have a 2011 with V&H CS1 exhaust, PCV with autotune. I have plans to get the ecu sent to Mr Nash. I have the bogging just off idle & the issues with cruising surges but lately I've started having it run on 3 cylinders, usually only lasts a few seconds. I looked at all the connections for the...

    86 Running like junk

    85 Running like junk Well my beloved but definitely abused in the past 85 is having some problems. To give everyone an idea of what I'm dealing with it looks like a blind person attacked the poor thing with sidecutters and an equally blind person tried putting the wires back together. Random...

    max running problems

    Long time story here. I bought max from guy who was trying to repair it and have had enought :ummm:. Problem was that max won't run correctly. It did not rev as it should and backfired. Making things not easy, sometimes it did run quite good. First I tried to use shotgun method to clean carbs...

    Strong smell of petrol after running.

    I have a stock '99 Carbon with 15k miles. It starts, runs and idles fine, but whenever I park it up there is a strong smell of petrol from around the dummy tank area when I get back. There is no sign of any leaks, but every time I start it up the fuel pump runs for a second even after a...

He was telling me that I know nothing about motorcycles (despite this being my 4th street bike, and I've had dirt bikes when I was a kid .. ) and that it was impossible for my bike to ever have...

    Running Rich

    My 98 vmax is running rich as I can smell unburned fuel. And the guy bought it from said it had constant v boost it has k&n pods and 4 into 1. The problem is after I come in town it wants to stall but I can keep it going after some spitting and a back fire up from the carbs. If I go back out...

    Running Lights

    Alright guys, the mod monkey would not leave me alone so I got a new set of mirrors that have turn signals built-in. I wired them up with my existing front LED signals and signals work great. The only issue is that my running lights were fine on the existing LED turn signals until I did the...

    Running hot on #2 and #4

    Just put the max away for winter hibernation and noticed the front 2 cylinder plugs were a bit scorched on the bottom of the rubber caps. Next season, I have to see where my AF Screws are, in relation to the back 2, and make them a bit richer. All plugs looked to have a light tan color and the...
