HC 103 vs 107" motor

So im board with my curent set up and wondering what would be a better bang for my buck. Putting high compression pistions in my stock 103 with head work and better cams or going to a 107 with head work and cams. For cams im leaning twards t man 600 or woods 555s. Do you rilly get that much more hp/tq out of a 107? Im trying to build on a budget and would install all my self this winter.
Its not a race bike just want a fun cruser

13 black fltrx 103, sert, se255 cams, vance & hines power duels, cfr mufflers, 14" pm bars, 21" pm wrath front 18" rear and the list goes on

Good question. I have been considering going to a FuelMoto 107 with my stock engine 2008 FLTR.

I would like to hear Fuel Moto's opinion, as they are the company I do all my business with. Very serious, will be headed their way as soon as things settle down here on the home front. I am facing the same question, leave it 103 with increased CR or 107. I understand from reading that FM really has their 107 kit really "dialed-in" with super nice results.

Interesting question. Personally if I had a103 I would have done heads, cams, etc. I had a 96 so I figured 11 ci was more than 10%, therefore enough to make a significant difference, I don't think I would've done it for 4ci.

Dragos has a kit that uses .010 pistons with his cams and heads. Shows really good #'s.

The real question is how quickly do you get bored? If you get bored quick, then drop a 124" in it and be done. Otherwise you will blow money for the two options mentioned, then drop more money later because you want more power.
