GL1500 wet spark plug

Postby vruano » Mon Nov 18, 2013 5:10 pm



HI, I´m having some problem with my bike, it started consuming too much gas, it smell like fuel is not burning, a lot of blue smoke coming out of the silencers, fuel drops coming from the exhaust pipe, and 1 spark plug getting wet.

I cleaned the carburators, they were dirty, calibrated the float level, change the main jet to the original #. The fuel consumption is now better than before, but the same spark plug is getting wet. The outcoming smoke is almost null.

Any ideas?

Thanks

Victor

Wet with what? gas or coolant. Which plug is wet? Each carb supplies a mixture to that side of the engine so unless the cycle is pointed uphill or downhill all cylinders would be affected from a flooding carb situation.

You need to check for coolant loss, then for spark to that cylinder. If plug is firing and no coolant loss you will then need to do a compression test of that cylinder and compare to the rest of the engine.

Follow this for checking ignition spark.

Thanks for the replies, the problem was the vacumm gas valve that is located in the fuel line after the filter. This valve is activated by the vacumm line coming from the right intake manifold exactly on cilinder No.5. Changed the valve with an aftermarket part (I live outside USA) and everything is ok now. The bike runs great!! I suffered a lot of time with this problem and looking in the internet found the Honda Recall of this failure.

Thanks guys for the advices.

Thank you for posting this issue. I also have that problem. I knew it was a spark issue of sorts and have not started to dig into it. Now I know another step in diagnosing the issue.
Its not what you say.. but what you do!
