XR250 spark plug.

All of you guys that have 96/04 Xr250s.Check your spark plug every 200/400 hundred miles.They come loose,and strip the threads.Always use thread sealant. When removing plug,if it feels like,It maybe taking the threads out.Turn it back in,lots of WD40.In and out small amount.We have seen a fair share of problems.I check our rental bikes,every 4days ride time when I service them.Every time little loose.BTR

I would bet that the plug in my 96 has not been out more than 4 times in 13,000 of. Hard off road miles.

Never ever came loose.

Your lucky,I see this alot. Dont know why, they come loose,others no problem.BTR
