I know this is a dumb question but i have to ask.

[Guest]

What are some of the the causes that cause a spark plug to foul out.

[posplayr]

oil fouling: bad rings/ valve stem seals,
gas fouling:rich carburation

[Guest]

Weak ignition spark

[Dave8338]

Plugs gapped too tight.

[tkent02]

Or way too cold heat range.

[Guest]

is there anywhere on here that explains how to check the spark. i have the tools but not real good with them.

[Guest]

Take the plug out of the bike. Put it in the spark plug cap. Ground to the motor and crank. Should be bright white-blue spark. If it is little and yellow it ain't cuttin it.

[Guest]

mines good and blue. maybe i just have my carb to rich and its fouling that plug out.

[Guest]

It's not oil?

[Guest]

if it was oil wouldnt the bike be smoking? mine dont smoke at all.

[Guest]

Oil would look shiny and sometimes wet.
Fuel is more like a flat black.

[Guest]

yeah mine just looks flat black.

[Guest]

I know you just messed with the carbs but I suggest you take a look at the float heigth, jets and adjustments.

[Guest]

ok will do. i know that me and steve , another member on here was trying to adjust the floats to what the book calls for but it wasnt allowing enough room for them to close and was allowing them to leak. so we had to set them at 25mm. i have the air/fuel mixture screws set out at 2 turns from lightly seated. maybe i should try turning them in a bit more. i went and got new plugs today but dont want to take a chance of messing them up , as that will start to get expensive lol.
