Working on a 2000 Softail Night Train for my cousin and it has become a train wreck. (Bike has set for 7 years). Root cause of initial damage was cam chain tensioner wore out and broke crank gear. After inspection we found nothing else broke. I checked the run out on the crank and it was in tolerance for a gear drive and that’s what he wanted to go with. At the same time he had rocker box oil leaks so we replaced them and verified no bent valves or anything when the initial damage was done. Rebuilt the carb replaced the battery, plugs and all fluids including flushing the tank and new petcock. Bike started and sounded good. Fast forward 3 months. Started having dead battery issues. Found the voltage regulator was bad. I replaced it and he bought a new battery because the battery that was only 3 months old was now junk from being ran dead so many times. Now the bike will turn over but then it appears as if it binds in something or the started just don’t have enough ump to turn over the bike. So being concerned something I did internal had backed loose and was causing a bind I pulled off the cam chest cover and see nothing obvious. Remove the push rods trying to isolate it from the top or bottom end and the bike will only turn over without the plugs in it. Which makes me feel all is good internally but now wondering is it the starter. When I turn it over and it stops you can watch the cam gears rock like they are trying to turn so the starter is engaged. Has anyone seen this? Could it be the starter? Really don’t want to remove it if I’m looking in the wrong direction. It just hit me. I guess I could push start it to see if it’s the started. But if it’s not that could be really catastrophic. Thanks for the help.
Update. It’s not the starter. Just put the bike in 5th gear and turned the back tire. I hear clicking in the engine something is loose. Looks like tue cams are coming out to see what’s going on inside.
It was the compensator. The nut backed off. Learn something new everyday.
Thanks for the update... I'm going to store this in the memory banks...
FWIW.... The early twin cams have had numerous reports of the compensator bolt coming lose.... I have never heard of it "binding" the engine and not allowing the engine to turn over... this is a new symptom to me, anyways.. or I may have suggested checking the comp bolt...
