Ride: '92 FXRS w/1340 EVO went to Cherokee, NC several weeks ago. The front spark plug blew out of the hole. I knew the threads were in questionable shape but the plug was fine for the 300+ miles down there & then also for the 150 miles that we put on while riding the Dragon & other places. i had to get my buddies to run to the parts store & get me a thread insert kit. I tapped the plug hole out & installed the insert right on side of the highway. My question is, has anyone had to install one of these, & if so how does it hold up long term? I rode the 300+ miles back home with no problems or bad symptoms. Haven't been able to ride for the last couple of weeks because we've had nothing but rain on every day I was free to ride. The insert still feels good & tight, it has "red" loctite on the threads. I'm thinking it's good to go for long term?
