Hello everyone.. I need some help. Any of you have a clue why my head pipe would get so hot that it started cooking my carbon heat guard in about 5 minutes? I checked the temp and it was 536 degrees! My set up is: 08 yz450..Akra evo full system, JD Jet kit.. stock motor The bike has been sitting for about a year (had back surgery) and the ONLY thing wrong with it is the Akra can is a little bent due to a crash I had last year. When the header was over 500 degrees the can only tested at 170, the cylinder head was about the same.. Any ideas?
