By rear fork do you mean the swingarm? Need a picture to see what the clearances are. Oh and do you mean you can modify the frame or can not because of laws? Would like to help.

Hi There Thomsengood

I have not done this but here is a Japanese Blog by a guy that has done it, use the Google tool bar to translate it and you should get a lot of good stuff from it

Sorry I can't help more, I am keeping me XLCH 1000 and me 04 883 well away from each other ;-)

It's going to be the spot just left of the rear motor mount. On Ironheads it has a notch to clear the pivot bolt/nut. You're prolly gonna need to cut/weld the offending portion of the primary case to make room, assuming you have the space behind the clutch, of course. Pics would be nice, but I think that's where the problem lies.

Looks like he mated an Ironhead rear section to an Evo front section. There's a couple of photos of the process.

Thanks for the replys, i dont seem to be able to post pictures( have tryed) your right its the space betwen the backside of the clutchshield and swinger that makes the problem, its that damn stator wire output. but welding is not an option for us here in Denmark, the authoreties wil confiscate my bike and fine me right into hell if i do......

Thank god the government is protecting us from all those dangerous welded bikes. maybe a freeze plug and then a new hole for the wires?

Then it must be a 4 speed Evo with the alternator in the clutch?

ya, some laws don't make sense. where i am the handle bars can't be more then 15 inches over your seat and to pass a safety i have to have a front break and both fenders

i have been looking at the inside of the clutchhousing and theres no room for moving the wires, maybe a swingarm from a 1979 sportster is a posibility, but i cant find the specks anywhere?

The '79-'81 swing arm is the same as previous models with regard to the pivot end that attaches it to the frame. Of course, it's a rectangular tube cross section and for use with disk brakes but that doesn't change anything for your purposes.

Yeah, I doubt the '79-up S/A will help. You're gonna need to reroute those wires, one way or another.

Is there anyone who knows if a rear swinger from a 2005 sporty will fit on my 1973 frame, that migt do the trick with the problem with space betwen frame and clutchhousing, it seems to bee a bit narrower than the original????

Not likely. The 2005 swing arm mounts to the engine/transmission case. The odds that it would interchange with a '73 are slim to none.
