One thing I have learned in this whole thing is don't listen to the stealers about these kind of parts. They don't know what they are talking about. I was told by 4 different dealerships waste of money time etc. I will get back to you, (one didn't) I have to check with the experts. Engine mods not big enough to warrant it. Its all garbage and its one of the best mods done on this bike bar none. The tech that did it said its not going to add performance he is now converted. He also has the same build as me on an Ultra and did my stage 11 and is going to do it on his bike.

No prob! rbabos and a couple of others are very detailed in explaining what it does and make it easy for the rest of us to self-diagnose if we need it.

Which appears to be most of us sporting the 96" motor...
Yes, glad you brought that back to the forefront Sniper, much appreciated. Has reversed my thoughts on changes going forward. I'm not touching any other performance modification until I've had my crank true'd and welded, the SE compensator installed, and the Timken conversion.
It is my opinion that building these motors without addressing the weak bottom end is like a body builder with toothpick legs. Too many people ignore basing a good engine build on a strong bottom end. It becomes especially important when dealing with engines designs based on torque and not just top end HP.... ie HD big twins.
I'd love to do a 103, or

Sniper, thanks very much for bringing this back up to the forefront.
Has made me rethink my modification path. The very first mods I do for performance, will be truing and welding the crank, installing the SE compensator and doing the Timken conversion. Only after that will I consider doing anything to the top end of the motor.
Every good performance engine, is based on a solid bottom end. More important when dealing with 'torque' engines. Just remember, there is a reason builders of performance auto engines that produce high torque, use steel forged cranks, multiple bolt main bearing caps, better oil pump..... etc...etc...etc.
The people riding the 88" bikes, I think have a better stock motor than the 96". But even they can come apart with a big bore build as well.
ah, I hate my touchpad!! I fumble finger the damn thing all the time, and lose posts. I thought I lost the top one... sorry for doubling up. :|

Ya know archer, one of the things to consider instead of worrying about the engine "grenading", is your warranty.
I've spoken to my service dept. about my build. The service manager has been in the hot rod Harley business for years and does a lot of builds out of his garage to make some extra money. I bought the seven year warranty with my bike so making changes has always been a concern of mine. His opinion on the bottom end to leave it alone for my first build (custom head work, cams, bb). If the bottom goes out it will all be covered under factory warranty. With the added expense of pulling the engine out of the frame, splitting the cases (about another 12 hours labor opposed to 8 hours for top end rebuild) it would be cheaper to let the warranty cover it than to "bullet proof" it on my dime.
I know every dealer/customer relationship is different but if you haven't talked to your dealer about doing the work and keeping everything covered under warranty it might go a long way to easing your concerns.

you dont realize how much that stock compensator weighs untill you take it off.
forget that
yet another reason i went to enclosed belt primary.
nice to know there is an option for those who want an up graded compensator
