RE: 1984 Evo project
A few questions to start with:
1. A double row primary chain is needed, correct?
2. What length of drive chain is needed?
3. How do you removed the transmission sprocket nut? I need to replace the washer behind it.
Any help is much appreciated.

RE: 1984 Evo project
Well, depending on how much has been butchered:
Yeah, standardinner primary 2 row chain. I've seen people use industrial chain and a master link, but you don't want to go there. It was really funny when he would describe his chain spitting out in front of him regularly at stoplights. That bike was probably 35 HP anyway, not a 96" stroker. So, just buy a primary chain set and you'll be fine.
Drive chain length will depend on a whole lot of things: size of your sprockets, etc. So, buy a long one and a chain breaker, which you'll need anyway. I have a little one about an inch across that cost a few bucks years ago. Works just as good as the fancy ones. Or, use a grinder and a punch if you're super cheap.
Use a wrench on the sprocket nut. I find that always helps. If it is all apart, an impact makes easy work of it. I'm trying to remember if that is left hand thread or not. It's been 25 years since I had to tear into one that far.
Get the Genuine HD shop manual on your bike. It is worth every penny.

RE: 1984 Evo project
I picked up the Clymers book, and need to do a little more research on the removal of the sprocket nut. I thought when i tried to remove it, it just spun with the shaft and wouldnt just losen with a crank. I'll try it again and look in the book to see if I'm doing it wrong.
Thanks again for your help, any additional tips are always appreciated.
Here is an acutal pic of the bike. Needs work, but its all doable in my eyes. The tank may be replaced, or just ground down to get rid of the paint. It has a small ding in it, so i might just get a new one. Still having a bit of trouble finding shocks for it on ebay. Not really to keen on buying shiny chrome shocks for my project, but seems I may have to...

Oh, you gotta hold the drive sprocket when you crank on the nut. That's where an impact makes it easy. Otherwise, you leave a chain to the rear wheel with your buddy stepping on the brake. If you don't have either of: A chain to the rear wheel, brakes, a buddy, then wrap an old chain around the sprocket, grab it with some vice grips and then hit the nut, preferably with an impact wrench. And I'm thinking it's left hand thread, but you're gonna have to look that one up because my books are at home.
You've got a pretty good start on a modern-day Captain America. Put it together and paint it and you're about there.

RE: 1984 Evo project
The sprocket nut is a left hand thread. If you want to go cheap on the very deep well socket(~$100) buy a 1 7/8" combo wrench(~$15) and a socket(~$10 to fit in a piece of 2 1/2" OD pipe. Cut the box end off the combo weld it on the end of the pipe. Did have to grind the ID of the pipe to fit the socket all the way in before welding. To prevent slipping on the nut, the box end should be ground down so the teeth are flush and will catch the nut all the way. Have used it several times w/air impact, works as well as the expense one. Depends on how valuable your time is. I like making a tool if I can.

JIREHS CYCLES has a clutch lock plate for 52.00 PN#97-189. This is a sure fire way to loosen the nut on clutch basket trouble free.It's always nice to have the right tool for the job. Good luck with your build !!
