Ok this year after it sit all winter with not mods due to a shoulder injury . my mileage on road king was bad. I had to do a firmware up grade to my thundermax tuner forced by the maker. my mileage was 33-35 way down from last year at 42-44 so i tried riding it and the auto tune came up but not great . So fast forward to memorial weekend I got 38-40 2 up on the way down after adjusting tuneing etc great i can dig that 2 up but cant do better alone.. Then the whoppers 70 degrees 38-40 ... 80 41-42 low 90s 43-45 i did get 54 2 up in the mountains at about 98 degrees but think its fluke .. no pinging and not running super hot feelin about normal for 90 . so i came home checked the tuner not codes after 2 days of sitting the head temp was 72 out side air 78.8 and the air temp 93.5 huh? so i checked no shorts or anything i could find. ordered new sensor air temp in garage 64 head temp 63 air temp old sensor 83 new sensor 84 ... what am i missing service manuals are thin .. i would think if outside temp is 64 the air temp should be close..
