When the 72 FX goes back together I'm going to run a wet primary and do away with the extra oil lines. Will I need to change the clutch discs to a different material to run in a wet primary environment?

When the bike was torn down the clutch plates in there now do not look like the old asbestos based material. The plates have a pink color and look to be some sort of synthetic friction material.

Plans are to use the original oil drip fitting for the primary chain as a vent with a line running up the frame tube.

 

If there's oil in there now with the OEM setup its wet, So if you isolate the primary its still wet, So yes it will work, when I isolated my primary I put a hose on the vent line and made a loop pointing down...

 

Crash69, Thanks for the reply. When I tore the bike down it was running a wet primary but all of the hoses were still hooked up. I just want the 3 from the engine to the oil tank.

On my Road King it has a vent hose on the transmission cover that has a nice 180 degree curl to it. That's what I plan on using for a vent hose.

The 72 I bought has great bones but was assembled by Bubba! Wiring was a mess, had both fine and coarse thread engine mount bolts and in other places, the shock mount studs are from at least 2 or 3 different bikes and the list goes on!

Will be fun to have a shovel again for a third bike, last shovel i owned ws a 79 in the early 80's. Plus they're so easy to work on compared to a twin cam with all the electronics.

 

Stock plates work fine, just level the bike and dump just enough oil in the derby cover hole to touch the bottom of the clutch pack and you're good to go. You can use regular primary.

I like the isolated primary even Harley figured it out..lol ..All those bolt ect. are not a big deal.. go threw the bike... ride safe...
