Dynas' run hot?
I have been reading a few articles about the 96ci engines running hot,or hotter than most people are comfortable with,And are concerned about the longevity of their bikes engine,To my understanding the engines are running hotter because of the engine management systems,running very lean condition to bring the emissions within acceptable limits,and i get the idea that running 'lean' will make an engine run hot and even create severe damage.I havent run my fxd at all,it went from the showroom to dealer storage as soon as the ink was dry on the paper.What can i do to get it to run cooler aside from running synthetic oil or an oil cooler?The combustion chamber,pistons/valves etc. Are still going to be running uncomfortably hotter.So i'm thinking i will have to do something to the fuel/air/timing to bring the temps down to something more acceptable.I'm here in maine and i dont have to have the bike 'smog tested' so i have a little wiggle room to make small changes.Any suggestions?

I put pipes and tuner and stage one air cleaner on my 07 SB....I haven't noticed it being too hot. It's gonna run a little hotter because it has a long stroke than the 88 but I haven't had any complaints to think of.

Syn oil and a cooler will help. A fuel management device that will work with the O2 sensors will cool the combustion process by enabling you or a tuner to make the mix a little rich.
