if your going to keep the motor one stock,the 48`s are OK.personally if your going to do something,ide do something you can really feel and wont leave you wanting for more in 6 months (and no,im not talking fire breathing race monster)if staying 96",ide at least pump the compression to 10.0-1 and go with a set of S&S .570 cams.but my real choice would be 107",mild 1.900/1.615 headwork & S&S .585 cams.this will give 115+120+ easy and still be very reliable and wont have you doing another build next winter

I have a 2008 street Bob with the 96". I've always wanted to do some work to it but had considered looking for a new bike. The new bike isn't going to happen so I'm back to considering building mine.
It is currently stock except for hi flow air cleaner, fuelpak and v&h exhaust. I'm thinking a cam swap and compression bump will do what I want, but I'm not sure what cams to run or which route to go for the compression. I'm thinking somewhere in the 10:1 to 10.5:1 cr range. And a cam that will cover general riding. Typically I ride alone, but occasionally have a passenger or some gear.
I know my fuelpak will have to go...unless there's a way to keep it and accommodate timing changes.
I'm not looking to build a monster race motor by any means, just want to wake up the 96 a little.
What do you guys think?

Assuming a constant being an 85cc chamber, we set the compression, via piston dome volume/gasket thickness, as needed.
And yes, cylinder head work will GREATLY enhance cylinder fill, allowing more power yet to be had.

For a 107 build with bored cylinders/new pistons, gaskets, modded heads, new cams, and a tuner - Yes, you are way low. Plan for around $2k-$2.5k if you do the assembly yourself. Also, don't forget the dyno tune - $300-$400...~$3k all in.
