The right cam is a bugger to get the belt on correctly because there's a compressed valve wanting to spring the cam about two cogs CCW. The way I get around that when putting on the right cam belt is to turn the crankshaft two cogs CCW (away from TDC) to match where the the cam wants to sit and then put the belt on, not having to fight the valve spring. Once the belt is on I turn the crank back to TDC to confirm the timing mark on the cam.

Voice of experience, I had done head gaskets, the bike was all back together, not running as it should. I did a carburetor sync (it was way off left bank vs right bank) but even after sync still wasn't running quite right. I pulled the timing cover, and sure enuf, the right cam was off a cog. Well, after putting the timing correct had to resync the carbs again (putting them back where they were) and she was finally running good.


They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:

Guys thanks for all the info...the cam wheels are exactly one cog off TDC...pulled the carb again, to see what carburetor bowl was flooding and found carb 3 float needle spring was not springing back freely. Going to buy a new kit and carefully bench test carbs, before installing it back on the engine, pulling the Carbs can be painful, especially in this muggy Mississippi weather :D
If you get aftermarket kits with a float needle they will most likely not seal off. Sometimes they do, maybe you will get lucky.

I sure hope I get lucky this time around...
