I bought this bike fairly recent. It had 21k miles on it. Upkeep was immaculate and bike runs amazing until the last few times I went out.
Oil is HD brand synthetic he had changed by dealer just before he sold it so I didnt change it(my Redline is coming in on Monday so all fluids to be changed next week). Oil is a bit darker but feels/smells fine.
Bike has True Duals with Rhineharts, SE race Tuner/Tuned and a K&N high flow under stock cover.
Bike runs amazing, starts, rides, and goes with no noise or issues. When I ride on the freeway or on the long straight backroads headed to the mountains at about 75 to 80mph for 30 minutes or so then come to a stop sign or light, idle drops low, below 1k and it will stall. I can keep it going by keeping idle at 1k. At the next stop sign/light it may or may not be fine. If it stalls, it turns over 6 or 7 times before restarting.
I checked the oil temp on the dipstick and highest i have seen it is in the mid to high 230s except when I was tuck in traffic in90+ weather after a long hard ride and it was in the 240 range.
Before I crashed my last bike, I had an amazing mechanic I trusted but he got sick and closed up shop. Now i am not sure who I trust and wanted to test out a couple with oil changes and smaller things before taking in any real issues.
Any tips would be appreciated. I will clean the filter tomorrow though it looks ok. I am adding some seafoam to the tank as well just to ensure the injectors are clean and I am sure the new oil will help. Bike runs absolutely perfect, it doesnt have any decel pop, has lots of power, everything so not really sure whats up. I am suspecting heat though that doesnt seem too hot to me or possibly injectors.
