Lets see if I can recall the info.
It has the Stage 1 using Vance Hines FP3. Have swapped the head pipe a couple times going from 2-1-2 to true duals and now back to the 2-1-2. Mufflers have been CFR's in the past, now Cobra 909's. No other engine mods.
Work that has been done. 5 water pumps, finally got the updated version from the M8 put into it and no further problems since 2019.
Rear motor seal and lifters around 40,000. Crank at 140,000 broke and took out the whole top end. Then about 155,000 the rockers went bad. I seem to recall compensator being replaced once and a couple of belts. All this work was done under warranty.
Knock on wood it has run like a champ since my warranty rant out in Jul 2022.
Oil has been mostly Harley Syn3, though lately I have been using Mobil 1.
Tires seems to be another hot topic. I get about 20,000 out of a set of tires. Was running the Elite 2's until Commander III's came out. I am getting more mileage and better long term wet traction from the Commander III's.
Ask away if you all have other questions.
