Several months ago, instead of putting money into the 110 motor that came in my 2007 SEUC, I installed a Jim's 131 crate motor and sold off the original motor.
JCZ and few other know me well enough to back me up when I say I have had just about every built motor you can imagine. I am like JCZ in that I am not about the highest dyno numbers you can find but for my main bagger I wanted cool running, stock starting and idling and good torque between 2000 and 5000 rpms.
I installed this motor with only a 54mm TB and the D&D borzilla with QUIET Baffle. Got the map for this from Zippers as I have a Thundermax self tuning ecm in this bike. (actually, I run 4 bikes with T-Max)
This bike is a perfect bagger motor right out of the crate! IT runs COOL in California heat. It starts and idles like stock and it can cruise around town quietly and at a very low RPM without galloping or otherwise giving away it's sleeper status. With the quiet baffle it is quiet UNTIL you wind it up on the freeway and even then it is still fairly quiet.
I consider it the ultimate bagger motor with mild manners and MORE then enough get up and go. Yes, I could change cams add compression and easily gey another 20-30 HP on the top end but I would not even consider doing so because the bike is SOOOOO smooth and mild mannered except when you really get on it.
Of couse as always, it has suspesion and brakes to match the power with quick stoppong ability and great conering capability.
For dragging my knees with my hair on fire,
I just ordered the HD 120R race motor for my 206 Dyna Bobber. I will let you know how that turns out.
Another interesting point is after selling off the old motor, it only cost about $6,000 for all the parts to do this. Not cheap, but you can easliy spend as much building up your original motor. Plus I got a one year warranty from HD!
