I just completed 12,000 miles on my '06 Classic with a Jim's 120 and a SE 6-speed. This is my opinion:
I love the motor (and trans).
114.23 HP and 116.5 TQ to the rear wheel with beautiful curves.
I get about 150-160 miles to a tank of gas, so it eats a bit more fuel.
I was surprised by how well it runs at low speed also. Has a bit of a cam burble and some shake at idle, but that's cool, and it really runs smooth off idle.
It can be a bitch to start after a long time in a parade ride in hot Florida (even using the compression releases), but they all are.
I eventually added a HD high-torque starter and the 2007 high-volume oil pump just for good measure.
At 5,000 miles it ate up a front motor mount. At 12,000 miles I changed it again just to be safe (although it didn't look too bad my vibration was increasing). New motor mount solved that problem.
At 12,000 miles I heard some funny noises. Result: one rear cylinder roller-lifter collapsed (the bearings in the roller itself), which caused the lifter to drop enough to ride directly on the cam lobe (which ruined the SE264 cam) and a slightly bent chrome-moly push rod. HD dealer did the repair. They called Jim's. THEY COULD CARE LESS. Very nice.
However, some insider info came out: Change the 4 lifters routinely every 10,000 miles. That's about all they'll go. I understand these lifters are made by Jim's for their motors and for Screaming Eagle.
And, change the front motor mount about the same time just for giggles.
Running strong again and ready to take on the world.
I'd give it 5 stars except for Jim's attitude.
I don't think warranty is their strong suit.
So 4 stars is about right.
