Try the float needle seat. I'm not sure if you turn your gas off, or its after 6 hours of riding. I would like to see the plug (pictures?), if it's not black, is it wet? Float too high?

I'm not an expert, but if your plug comes out looking normal, chances are that it's fine and not buggered. When they are too rich the build-up of carbon on the insulator will cause it to overheat. Too lean and the tip of the plug and part of the piston will melt away. What is making you think your plugs are failing?

question

does it stop running or runs like crap? you change the plug when its hot and vroom?(the time it takes to change a plug it has already cooled down)

if so your cdi or coil may be taking a crap, when it gets hot those parts fail but work normal when cold

^ +1 to the coil...

try not changing the plug and let the bike cool, and see if it will start.

My '02 WR 426 suddenly started not wanting to start and with a new plug it would fire right up--for a while anyway. Then the no start wasn't cured by a new plug and when I did get it going it would pop and backfire and bang in the exhaust. I found out that the stock CDI had given up and was running on a default, retarded timing setting. I reluctantly bought a Vortec X-10 CDI box and it cured the problem instanly with the added benefit of the incredible adjustable new CDI box that made the bike run like it was better than new. My experience with the info you have given so far. WR Dave.
