    Plug not firing

    My left side rear spark plug is not firing on my 1996 V-Max. Changed the plugs Checked the wires (nothing obvious) Checked the coils (also nothing obvious) Started it in the dark and there seems to be a spark that flickers briefly but it is so quick, I can't see where it is at. The spark doesn't...

    Spark plug soaked in fuel, stuck slider?

    I have a 2000 Max with 73,000 miles on it, stock carbs, jets, and exhaust. For the last 4 months, it has been running as if one or two cylinders are not firing. At a red light, the idle will switch from perfect to a stutter (like a Harley), then back to perfect, within the same red light...

    No spark from one coil

    Hey there! Just picked up an '88 Vmax that was inop. No back history, got it cheap from an auction for a project. Anyway, put a new battery in and am trying to get it running. Found really old, nasty gas and have drained the tank and cleaned it out. Will be pulling the carbs and cleaning them...

    Question regarding No Spark on Cylinder 4

    Hello all, I am currently having an issue with a no spark condition on cylinder 4 (R/F) and I am wondering if there might be something simple I am overlooking. The bike is a 1988. I suspected bad wires or a bad coil so I swapped a known good coil and wires from Cyl 1 to 4 and the problem...

    New Battery? No spark?

    My bike died on me last month and the battery was flat and wouldn't charge. Prior to this it had been running fine. I replaced the Yuasa 12v 16amp battery with BS 12V 18amp, which was of the same dimensions and a perfect fit. Since fitting the new battery I have had a 'no spark' issue and the...

    NGK Platinum Spark Plugs?

    I had a plug die on me, so decided to swap them all out. I was intending to replace them will the same NGK DPR8-ea9, but the store was out of stock. Instead the guy recommended an alternative NGK plug which he said was a platinum tip. I can't remember, but I think it was something like DP8-efg...

    Changed the spark plugs in my f150

    I am sure glad plugs these days last a long time. 130,000 miles on this set. The gap was .074 on the old plugs .054 is spec. I have an 06 with the 4.6 liter, while it's not the hardest job i have ever done, it is very involved. Makes working on the Vmax seem easy. I finally bought a neat...

    Number 2 cylinder spark plug

    Ok.. so after reading many issues on this forum.. the bulk of the issues can be resolved by cleaning the carbs. Now I have cleaned mine thoroughly twice.. every orifice and jet has been cleaned, the float valves were leveled off. I synced my carbs once I put them back on. Now the reason why i...
