RE: FLHX overboard
Hello releg63,
The difference you see across the band is due to comparison between balanced and unbalanced engines; especially, you can never get the kind of low-end torque you can get with an unbalanced engine. Not sure what cams you're using, but I'm assuming you're using the 54mm manifold and throttle body and have a fairly recent map for the Boarzillas. At any rate, they're close and both are exceptionally fine engines, so you can't go wrong either way. I look forward to seeing your Dyno sheets when you get a chance. Take care.
Also, to the dude who asked about the EFI, the answer is yes and you can configure for EFI easily. Fortunately, as well, you can install Zipper's Thundermax EFI and 54mm manifold & trottle body for the JIMS 120 along with your choice of either Bub Rineharts or D&D's Boarzillas with maps. I'm pretty sure they post the Dyno sheets for that configuration as well or else I may have had them send copies to me, I can't remember. See if I can find them and post a copy. Take care ya'll.
Ride safe,

axe11,
I agree the balancers may rob a pony or 2, but not low end torque. it will take away some high end with it's lower rev limit. The zippers kit I am running is their standard 120 muscle kit with an updated ecm. My numbers are actually down 10 + 10 from their advertised dyno (B motor). Zippers dyno is actually closer to what I'm getting out of the jims motor.
I attached my dyno sheet in my first post and a couple of bike pics in my 2nd. If they did not post, let me know and I'll try again.
