I've never noticed any excess heat on my '09 CA bike and it's totally stock. No oil cooler, no PCV or anything like that. The spark plugs look good and no excessive heat. Not sure why but that's just how it is for my particular bike.
I believe the new exhaust design is for the passengers benifit, not the drivers.
Mine's not bad, but it's still pretty warmish on my right foot. But I do have Lowers and it was better this summer when I took the vents out.
I put them back in the first of September. I should have waited until the first of October. I do live in Texas. DAMN it's still HOT here.
