gents the thing that I cannot understand is, I clean the first sparkplug and the bike run perfect all the day.
when i start the bike the next day I get the problem with the first sparkplug getting black.I clean it up and it works good again.
so every time that I want to ride I have to clean the sparkplug
Next time before you clean the spark plug, take a picture of it and post it. Also be sure you have the correct spark plug gap. Manual says .040

Let's see a picture of the front and rear spark plugs side by side.

Try to focus the camera on the plug please.

I think the stock jets are .0295 or .031 intermediate and .074 or .076 main. not positive on this maybe someone will chime in on this.
there are 4 screws on the bottom of carb to remove fuel bowl,then you can see jets.
By the looks of your avatar, it looks like you have big radius pipes so jets may have been changed unless you put them on.

He probably has a 31 intermediate and 76 main if its stock.

easyrider, did you take the intake manifold off of the bike?
Also what are you setting the spark plug gap to?

I am the second owner of the bike.I buy it in pensilvania from a dealer last year.
the only thing that I change was the stock ignition module for the thunderheart ignition module and the EHC for the wireplus.
I burn the stock ignition and the EHC.
RRRuff what do you mean with setting the spark plug gap to?
