Hey fellas, looking to get some info on this trans that was installed on my 1980 Shovelhead FXEF. From what I can tell, it's a Revtech 5 in 4 trans but doesn't have a kicker. The only add on kicker kits I can find state that they only work for 5 speeds but not 5 in 4 case. Anybody have any ideas how to add a kicker to this setup?

This is all that I have of the kicker ...
Uses 4-speed kicker cover ...Take my 45 and outrun em all .. -
Do you have pics of the transmission you have? This might help identify or help someone know what kit you might need.....Comment

The description says it does not have provisioning for a kicker. Pretty obvious that it would require a new cover, kicker arm and spring, and shaft, but I'm not sure what other internals would be needed.Comment

Yeah I saw that one but it says that it won't work for a 5 in 4 trans. 5 speed only.Comment

It says it doesn't bolt on but it doesn't say WHY. The advert also says:
which gearboxes use later transmission case styles than what you have but are not necessarily incompatible. '87-'89 also have the tapered shaft but I don't know if shaft length is an issue vs earlier boxes. They are desired (pre a Dragstews post) for S&S case 5-into-4 conversions to use stock Shovel clutches. What I don't know is the different transmission shafts (it's more than just tapered or splined clutch ends) and I don't have examples handy. Dragstews and JBinNC may be able to enlighten us. I know Drag's done 5-into-4 using S&S cases of which the Revtech is likely a direct copy. That RevTech case obviously fits '86 and prior five speeds because there is one inside it!B - Fits all Big Twins from 1987 thru 1989 ... contact Paul about availability ...
Later five speeds fit older cases (installed as a unit!) therefore if a tapered shaft kicker kit fits later taper shaf transmissions AND that shaft length works for a Shovel you should be able to drop that combo into that box. Example thread but many have upgraded older cases (including 1986 style) with later gearsets: https://www.hdforums.com/forum/evo-c...r-i-did-3.html
Of course that means buying a kicker kit, matching transmission (takeouts are cheap since spline upgrades are popular), etc. Probably about a grand total by the time you're done.
I wouldn't do that to my bikes because it's too much work for what I consider an inferior result. if one of my Shovel four speeds needs rebuilding it'll get replaced by a complete splined shaft Softail transmission with primary and starter. That Denso starter eliminates any functional need for a kicker but of course they can be added. I offed my '88 FXR box for a later transmission and am fucking delighted.
This is the expensive new aftermarket version of that swap but the instructions are essentially the same: https://www.streetchopperweb.com/upg...in-shovel-techLast edited by farmall; 05-30-2019, 9:59 PM.Comment
