The guys at my shop telling me the Race Tuner is in so I'm looking for input based on members' experience for upgrading my HD 110 motor. I'm open to any suggestions as I am not out to reinvent the wheel. My riding style is mostly 1 up. However I try to take 3 - 5 road trips where I'm loaded for bear. Tour-pak, T-Bag. I carry my extra pair of jeans and all the stuff my lady wants as she can't carry much on her Road King Custom being a new rider. Most of my riding is in the 2600 - 3000 rpm area. I love to ride in the mountains. Maggie Valley last year. Custer and Badlands next year. I'll average at least 10,000 miles a year. I ride until it snows and start when it melts.
I'm looking at the following upgrades:
HD Heavy Breather - I like the look but I'm concerned for when I'm stuck riding in the rain. I would think the rain sock would starve the motor for air. Any one running something similar to this? Problems? I have been told at this time the AN back plate and KN-800 will not fit with the stock air cleaner. Any one find a way around this problem? Is the KN-800 better for all weather riding than the Heavy Breather ( which has a KN filter on it )?
Rinehart True Duals - love the sound and am willing to loses the little a 2 to 1 system would offer.
Cams - I'm looking for something that is designed for the 110 motor. I m after low end torque to get her going. HP while important is secondary as I rarely get high enough in the r's to use em. Should I switch to gear driven or stay with the new chain system in this motor?

The 255's seem weak in the bottom.
Heads - The guys at my shop are recommending T-man as they have made "good numbers with everyone they've done." Should I have the stock heads polished and ported? Use T-man heads?
Oil pump - stay stock or go with Fueling?
Throttle body - Is the stock 50mm good enough for my needs? Modifications? Replace?
Warranty - My shop will back all their work regardless of Moco position. If a major problem happens far from home, I have access to transportation anywhere in the U.S. (Brother has it covered with his business)
Build - I am leaning towards making all the above upgrades at one time then doing the Dyno. Would anyone recommend I put the A/C and pipes on with a canned map in the SERT until winter or just ride it stock until winter and do the whole build then? I'm not sure I have that kind of will power as the stock pipes drive me crazy. I miss my Rinehart rumble.

I am trying to build a 110 motor that is reliable and strong. I am not looking to make a monster. My 07 Street Glide had SE A/C, Rinehart's, Race Tuner and made 94 hp / 114 tq. I was OK with that but she was weak bottom end. I would like to be in the 110 -115 hp / 120 - 125 tq area.
I've searched our site and came across a lot of info. As the 110's are still so new, I was looking to start a discussion on the latest our members know on them. One thing I immediately realized upon my reading. This can be a slippery slope. I found a post from Hoist in Nov 06 where he ask a lot of these same questions as a new member to this site. I have followed his build so I know how easy the motor monster can attack. No offense Hoist. You have one sweet scooter and one monster between your legs. Many great miles to come.

I am here to learn from people who love their Harley's and take care of em as much as I do. I would like to thank all in advance for sharing their knowledge and experience. I'm sure I forgot important details need to assist in giving me direction. Just ask me and I'll get right back to you. When responding, assume I have zero knowledge about motors and you are pretty much on the mark. I want to learn so I don't spend money needlessly or can't make a decision based on some knowledge. I am looking forward to this build. TIA.
