Possible 107 build
I see a lot of guys on here running the 107 on their bikes. My question, what did y'all have to do to get it installed? I've heard some guys talking about case boring, and crank replacement. I've got a 2002 FLHRCI (road king classic) if the 107 is an expensive *** build, what else would work? I'm just not happy with the power the engine is producing, and I want more grunt when I twist the throttle. I mainly run highway and city. NO racing. I'd like to upgrade to the fueling cam chest kit. With gear drive cams. Anyone had experience with it? Is it worth the money, or junk? I just haven't decided on a cam grind yet

A 107 is going to be expensive because it requires a new new flywheels and splitting cases. The largest bore possible from an 88 would be a 97 or 98 without splitting the cases. The most common being a 95". The best advice would be to find a cam that is in your common rpm range (sounds like something similar to an andrews 26 or 37 or comparable) and build the rest of the engine around it. Good choices on supporting mods are going to help (not true duals/straight pipes). A GOOD tune to finish it off.
Last question...How deep are your pockets?

Ok. So the 107 is out. I'm looking for more of a bolt on kit. I was searching, and I found a revolution 98 inch kit. Not too bad of a price too. Anyone have it installed on their bike? I'm looking for reliability more than anything. So flat top or domed pistons? I wanna keep the compression ratio at a reasonable range. I'm out here in Texas. The heat in the summer is brutal.

another good 98" build is setting the compression to 10.0-1 and use S&S .570`s.whoever you go with,ide steer clear of the nikasil,REV PERF kit,too many problems & unresolved issues with them

If you are going through the install of cylinders and piston, I think it is really smart to go ahead and get headwork too. The overall result will be much better.

Lot of good advice here. I have a 95" build on a Dyna w Andrews 37G some compression, headwork, and larger carb / intake. The bike rocks and is the fastest Harley I have ever ridden.
Don't sweat it, but if you do everything a 95" is all you will need.
