The thermo-bob is an awesome product. I once got stuck in a traffic jam with my klr on a hot summer day when it was still stock. I had to turn it off twice because it was running so hot. Once I put the thermo-bob in I never had an issue like that again.
The 685 kit was actually gonna be my next big project this winter on the klr until i decided to sell it. I'm trying to convince the new owner of it to still go for it. i just want to see how much of an improvement it is.

Instead I'll be doing the carb, airbox, and exhaust on mt klx now!
