I have a '66 duoglide and am having problems with it staying running. It'll start easy and run untill it seems to warm up and then it wants to die, sometimes even while I am giving it throttle. What can be causing this and how can I fix it ?
I would start with the easy stuff.
Fuel Filter.
Make sure gas cap is properly vented. If the cap vent is not working it will cause the bike to sputter and cut out
S&S crb... Mallory electronic ignition...basicly stock after that.
