Figured I would join to see if maybe someone could help with this issue. Picked up this old 79 xr185 couple weeks ago for $250 bucks. Guy that owned it thought it was a xl125. So when I got it home I pulled off some stickers underneath revealed the xr185 decals. The bike had a small oil leak on the right crankcase as well as non working kickstart return spring. So I took it apart and the spring fell off the follower cam. That's no big deal but then when I pulled the crankcase off the piece on the spindle fell off as well. I have posted some pictures I can't seem to get them to line back in order to put the crankcase back on the bike. Any help would be greatly appreciated thanks ahead of time.

Re:1979 xr185 crankcase kickstart spindle/follower cam trouble.

The parts in question are actually part of the decompression assembly which is actuated when the kickstart shaft first moves. If you'll notice on the kickstarter cam, there is a small punch mark. This should be aligned with the punch mark on the kickstart shaft. The spring and cam are slid onto the kickstart shaft in said position. When the Right Engine Side Cover is ready to install (gasket in place) , you may have to slightly wiggle the decompression lever as you get the cover close to home. All this while you pre-load the clutch lever. It is a little tricky but it will go. Good luck,

 Just wondering does it look like I have the follower cam and spring installed correctly? Also thanks a lot I now see that punch mark got the kickstarter cam straight. I just gotta figure out the follower cam and clutch part and all will be well. Thanks a million.

It appears to be in the right position. A little preload on the clutch arm and the decompression lever and it should go right into place. One side note: make sure the cover goes down completely flush on the engine case. I've seen people try to crank it down with a small gap still present, only to get a cracked side cover out of the deal, because something was still not quite aligned right inside...

 Well I really appreciate the help honestly. I'm just waiting on a right side crankcase gasket them I'm pretty much done. I Just don't understand how that spring seems to engage reverse of the kickstart shaft. It would seem to me that the spring should actually be loaded from the other side. The way I have it is the only way it fits though. The spindle goes down the spring is loaded upward you would think it would make the spring fall out. I guess maybe I need it all hooked up in order to work correctly.
