86 FXR trans updating?
I am wanting to update the old tappered shaft transmission in my 86 FXR. Was wondering if anyone on here has done this before and/or has any info on doing this, ex.. can i keep my trans case and just swap internals? whats the best year parts to look for? can i use my inner and outer primary cases? any info will help.

This winter I'll be doing something similar; I'm installing a Baker OD six in my '86 FXRD. To go from tapered shaft to splined you will have to get new tranny internals with the splined mainshaft and will also have to replace the entire clutch assembly with a later model assembly with splined keyway. I believe '89-91 would be a drop-in. I'm going with a Baker SP8 complete unit, but that is just my preference.
Tranny case and your primary cases should be fine. I'm not positive if your lever actuated clutch arm will be compatible or not. I recommend dumping it for a ball and ramp right side cover. I picked one up on Ebay for $40. Rumors have it that the actuating finger on the stock '86 set-up is a real weak spot.

No problem just swapping internals, any 5 speed gearset will fit into your case.
`90 or later will have a splined mainshaft.
If you use a `90-`93 clutch your primary and starter gears will remain the same.

The information I gave you applies to all 5 speeds in all big twins.
Softail, Bagger, FXR, Evo or TC, 5 speed transmission guts are interchangeable.
But feel free to get your information elsewhere.

I am still wondering about the # of teeth for the starter gear remaining the same between an 86 and a 90. The 86 starter clutch is external and is moved by the lever and external solenoid system. A 90 has internal clutch and solenoid with jackshaft system. So far the only responders have 89s which are similiar to 90s in the starter system. Some one doing an 85 or 86 has ALOT of differences to overcome. Does a 90 clutch bolt into an 85 if all you replaced was the keyed mainshaft with a splined one? Absolutely no other mods required? My 85 starter clutch will mesh perfectly with a 90 ring gear? That is the juice we all desire!
