If the engine ticks over on both sides but cuts out on left side at small throttle openings, try removing the plastic pipe that drains the frame into the left inlet tube. Blow down it and listen for bubbles in the frame, the bottom of the tube should be in oil. That could be where the air is getting...

I had to file the holes to get mine close enough to pick up a signal. When you get the ignition sorted you can look forward to hours of fun setting up the carbs.

Make sure that the plug caps are 5000 Ohm suppressed, 10,000 at the most.Remove the plugs and earth them to the fram so you can see the spark. On the three pin plug with brown,yellow and white wires, connect a 12 volt 5 watt test lamp between negative and the yellow wire, the lamp should glow. Spin ...

I bought my Commander in 1996 and always used 4 star. Now I use BP Ultimate with Castrol Valvemaster. 140,000 miles later and still 54mpg. E10 is not worth the risk.

Is the problem only when the engine is hot ? Sounds like it could be an air leak. Make sure the idle pipes are fully into the engine casing, a light tap with a blunt screwdriver will do. Try a smear of instant gasket around the pipe to see if it helps. If your bike has the crank case drain modificat...

Is the oil pump set correctly? Long downhill runs on a closed throttle can cause plug fouling.

I am that rider. I live in Horncastle and have owned the bike since 1996. She now has 130,000 miles on the clock, still on the original chain and sprockets. A new voltage regulator and ignition unit repair were needed last year, but generally reliable. I clean the carbs vacuum chambers as soon as th...
