I think the Mother Ship made the 2014 Limited at 10.1 this year, so I don't see at 10.5 it would hurt anything. I'm waiting on my jug's and pistons from WFO Larry's right now for my 107 build. I'm installing TW555 cams, Ported heads with 1.9 intake and 1.610 exhaust valves at 10.5 comp. Sure hope it's a runner.

Good stuff. The guys at Fuel Moto seem pretty comfortable with a 10.5 CR being very reliable for touring and not too much stress on the lower end. They've been putting these in for awhile now and say they have had none or very minimal issues with them.

My 2001 FXD 88" stock was 8.9 with a better bottom end and my crank runout was .019. Put in gear drive and kicked it up to 9.4. The second owner is up to 84k and says it still runs strongI haven't but a stage 1 in the current bike and don't feel an aggressive 10.5 comp build would go 80k with a stock bottom.
