Drive Belt Tension
I have an 07 with 20,000 miles. The belt has about 1/2 inch of deflection to it when cold. When it gets warmed up, the tension is good. the dealer says this is because when the metal gears get hot, they expand taking up most of the deflection. This seems like a lot of expansion. Has any one else had any experience with this much expansion. Also, I live in the Phoenix area and I am currently running 20/50 full synthetic oil with 10% Lucas additive. The reason for this, when I come off of the freeway after about 1 hour running in this heat, the engine sounds almost like there is no oil in it, it is so noisy. When it is cold, it sounds quiet. It even has an oil cooler which is why I don't understand why it seems like it should be getting so hot. Any ideas. Great bike except for this and love it.
