"Yeah, it had I believe 16k miles prior to be buying it 2.5yrs ago. Only been able to ride it about 6 times in the last year due to European weather. I thought engine kits came with cam's?"
Engine kits do generally come with an appropriate cam. Hillglide was referring to simply doing a cam swap in your current engine as it is now. Not replacing cylinders, heads, pistons, etc.
I did the traditional Stage 1 upgrades and then after my first 1,000 miles, elected to replace the cams in my 103 H.O. I am mostly pleased with the results. It will completely depend on what you are looking to get from the engine. If you have some idea of how much HP/Torque you want, the next question to ask is where do you want it in the RPM range. There are lots of cams to choose from and so many different designs that you would be sure to find something to produce the power where it would best suit your riding style.
