I put on a vapor trail tech and today we went out for a 120 mile ride. It varied from 155-180 all day started at 60 deg air temp and got up to 75 or so then we rode on the pipeline in some sand thru jumps and ruts for 15 minutes I look down and it was at 215 deg so from then we headed back to the truck it cooled off and ran out of gas refilled then the temp was 160 when cruzin 70 and when we had to slow for a speed zone it got back up to 195.It didnt do tha all day. Its top end is shot piston slap and 140 psi left. The radiators were cleaned and check over but I used the original cap 50/50 pre mix coolant I bought. Any ideas. I thought maybe from running out of gas it was leaning it out while working it in the sand. I have the stock exhaust on it and the plug seemed plenty rich. but it still got hot after I refilled it. I run 32-1 r-50 klots with premium gas.
