Engine was f**ked in a year. I kid you not.
The rest of us had mechanical sympathy, our cars and bikes...
1st start of the day in cold temps, I'll idle it until some heat is showing on the gauge. Otherwise I'll just let the fast idle reduce and go.
I'll never cane any engine until it's showing normal driving temps
