Re: Cam change
burkey,
More info necessary: By hard starting, do you mean you're kicking it excessively to start ??Many, many times.
Or do you mean it has too much compression to give it a good down-stroke ??
If the second is the issue get a "Stroker Kicker Arm"
They are 1" longer & mathematically that equates to min. 50 more pounds of ass on you. Easier to kick..

Re: Cam change
Billy, It has too much comp 130 lbs for a good down stroke if it does not start on first few cranks I am out . a cam with a wider lobe separation angle and duration change may kill some of my crank comp to help me so what is good cam to go with.

Re: Cam change
Changing the kicker arm is $$ easier to a 1" longer Stroker kicker arm.
burkey, 130 psi is good compression. Not excessive.
Some people would be very happy to have those readings.
If you don't believe me about the longer kicker, I'm serious & it works.
Before any further, we are talking about a 74"FL right
how much is it over-bored ?
Does it run bad ?
Are your valves over-sized ? If your valves are over-sized, this is NOT the way to go.. As a cam with a good bit of 'overlap'[lot of duration] will possibly/likely have the valves wreck into each other.

Re: Cam change
Billy is right on with the longer "stroker" kicker arm.I put one on my1962 that is a 93 incher and It was a graeat improvement.Also I run a multi grade syntetic oil. the syn.oils are more fluid when cold.and get thicker whith heat, the opposite of dino oils.So its alot easyer to kick over on a cold morning.I think that to go with a cam with a large overlap will hurt your overall performance and won't ease your starting.Work on your setup:timing,carb adjustment and jetting,plugs,ignition,etc..with a new engine it takes time but it will get easier as you learn the starting "ritual" for your paticular bike and the engine gets broken in.and when you do get it rite... it dosn't get much better than that feeling of sweet running pan down the road.
goodluck
