Great build. I got a ultima 127 in my kenny boyce fxr pro street frame. That motor is nasty. Great motor for the price. That motor will last you a good while depending on how hard you are on it. It's obviously not the level of an S&S but it's half the price also. I love the ultima crate motors. Stay alive on that thing. It's gonna be a rocket ship 🚀
They suck with a stock engine because of the old single piston caliper. I had dual discs with those on my 1988 FXR (got the kit when I bought the bike new) and upgrading to later takeoff four piston calipers was like night and day. I'm in process of putting an S&S V124 into the '88 which I'd already converted to a bagger box to get the spline shaft trans and lose the goofy oil tank. That was a very useful mod because it upgraded the starter from Hitachi to the more powerful Denso. He can order the later 39mm dual disc sliders and keep the rest of his forks.
So how's that motor workin' out for ya? Thinking about rebuilding an old Road King with one of those motors. Was looking at S&S, but found nothing but people complaining about 'em....
I have the 127ci Ultima Black Chrome and Ultima 6 speed in my Road King, have had zero issues with the motor/trans. Wife rides with alot so I have added alot of touring options..batwing, bars/lowers, original police hard bags, and a tour pack from a 2008 ultra just got added as well....motor doesnt care...it just goes....it easily wheelies if that's your thing....hope it helps.
