this doesn't really have anything to do with my spark plug but I didn't wanna open another discussion but I tested my temp on my fourwheeler today and the engine was well over 220 degrees. I couldn't tell how much higher it was though beccause that's as high as my thermometer goes on it. My question is is this too high? I was riding at high speeds the whole day just about, and I was only riding for about an hour. And I also have lost some performace I think. It doesn't seem to be as peppy as what it was, and the ticking sound in the engine is getting a whole lot louder. I'm going to switch to regular gas later to see if this'll help it. I hope that that does it. Thanks.

 

If the ticking noise is getting louder I would get it checked out soon. It sounds like you need to get your timing chain or the chain adjuster checked by a dealer.
