Default 1985 FXWG

I’m getting working on getting the wide glide running, however I’m in a bit of a dilemma, probably why the PO never got it going. The inner primary cover is the issue, it musta spun a bearing and the PO had it welded however they never finished the job it’s just a blob of weld. I’ve been looking for used inner primaries only to find out they are extremely rare. I believe the HD pn is 60444-84 I know it has casting numbers X30-00085. Anyway I’ve decided to get rid of the belt drive and go with chain and sprockets because I have a brand new Shovelhead chrome inner primary cover. At this point I’m looking at what sprocket sizes to get. I’m thinking 49/24??

A little confused hear.. This 85 WG is it an Evo with 4 or 5 speed? Are you looking for an inner primary setup? 24/37... Or the secondary drive?... A 24/49 secondary would give you an overall ratio of 3.15:1.. A 23/49 would be my choice with an over ratio of 3.28:1
An 85 FXWG inner primary is part number 60414-84.. And pretty sure it's a 4 speed and with that a 23 sprocket on the rear is as big as you want to go because the chain will wear into the inner primary housing..

Thanks Bud, unless someone happens to have a rear belt front chain inner primary I’ll stay rear belt, otherwise I’m going to run secondary chain and sprockets. And yes it is a 4 speed.

Will the shovel inner primary work with your starter? Never worked on any 80’s EVO’s but seems to me you may run into issue?

I Own a 1986 FXWG...Remember that the Outer Primary is a 9 bolt...most older 4-speed primaries, are 8 Bolt.. I do Get away with an 8 bolt gasket,if I'm careful.. I have always run chain Primary/Belt Final. as Stock.
If it was a bit more Economical, I would go Belt Primary with a New Clutch as well...as I detest that L'84 Clutch!
Never have had Problems with a Belt Final...except at the DragStrip...then it is Avoidable if one pays particular attention.. Might change If I end up with an S&S engine in it..certainly if a 124!!!
Edit; I will need to look more carefully at the Starter..I have Not paid it much attention...thinking it must be just like any other 4-speed Starter...But, IDK.. possibly something Changed with the Belt Final ...what? around 1982??

Nuther Edit: I feel you will get much Better results on the Shovelhead Section...as I see zero difference except of Course the Evo Engine, and Frame Modifications done by MoCo to Fit it!
I am Confident that the Primary and Final are all the same since the First final Belt 4-speed..again Guessing 1982

Yeah if you compare that 85 4 speed frame to my 98 heritage frame the front part is damn near identical.
