I have an FLHTCUSE3 Coppertop with 04/08 build date. Bike was stalling out of the hole with excessive heat and zip oil pressure as the heat increased. The MOCO advised I have the new cylinders and guides? Was the first at my dealer to get the update installed on August 8th and the following action was performed: They removed seat, console & fuel tank, right side footboard, heat shields, saddlebags, disconnect mufflers & exhaust system, removed rear cylinder heat shield, air cleaner, top front stabilizer & both upper rocker boxes, spark plugs front & rear rocker carriers, push rods & tubes both lower rocker boxes, horn & bracket, head temp sensor, throttle body, both cylinder heads, both cylinders and disconnected connectors from induction module. They inspected cylinders bores for any damage and reassembled engine with new gaskets, ACR solenoids and replaced the crankcase bolt. The MOCO accessed 5 hours to complete, it took a good 6.5 hours and the mechanic cranked.
Outcome: After 80 miles in moderate heat it is running better, but a real test is yet to come.
Ciao,
Ron
