I've been following another thread here about final drive chains and didn't want to highjack the thread.
I've got (for all intents/purposes) a stock '79 FXEF. I understand that some modified bikes have very close tolerance in this area, am i correct in believing that my stock bike won't have a problem if i put on an O-ring chain? When do i need to be concerned about clearance in this area?
You could wrap some silly putty around the chain and feed it around the front sprocket. It should self clearance and give you an idea of how much room there is. Obviously, if it's close, you may have to find something else that's more precise.
Also, if someone is considering this for a different model, the 65-69 aluminum primaries were different and should be evaluated separately from 70-84 specs.
Here is some more info about my bike, if that helps
-1979 FXEF Fat Bob 80" (heads are leftover 74")
-4 speed Cow Pie tranny
-BDL 11mm x 1.5" closed belt drive
-tranny sprocket is 23T
-rear wheel sprocket is 47T
I have run an o-ring chain on a 1984 4 speed forever....I don't remember having any clearance problems...but I would have just whipped out the die grinder, and made clearance if there was...
My '79 FLH is running an o-ring chain since
2002 engine and transmission upgrades with
NO issues!
What brand did u use....just getting ready to swap out chain and tires. I can cut the primary if i have to i guess. Just no more oil sligers on this one...
