Been doing a lot of research on cams for this 110's. From what I have found out these motors need a lot of lift and a little less duration than you would think, @ 244 ( no more ) will work the best on a mild build and very few mods due to the design of the combustion chamber, compression, port design and air flow. If you don't do some headwork, up the compression by changing pistons and few other mods, you will not get a good power band from low end torque @ 2000 to good pulling power to 6000. A so called bolt in cam moderate lift and no other mods will be disappointing. It will only move your torque curve up to come in later and that's not what you want for these 110's in heavy bikes. ( unless your looking for big high end power at higher RPM's ) And then you will need more mods to ensure they will hold up at these higher RPM's. If you are serious about changing cams for more torque and a longer power band, then I highly recommend upping your compression to @ 10.1 to 10.5 by changing pistons, do some cleanup work on your heads at the least, add a 51mm TB, good 2 & 1 exhaust ( D & D ), Hi Flow air filter goes without saying and then you can go with a good lift cam. A 625 lift 244 duration with @ 44 overlap would be and excellent choice !! This will work with your stock heads, after changing valve springs ! I'm sure there are good builders like Cycle-Rama or T-Man Performance that offer these cams.
