jackshaft question
I am in process of changing out the clutch basket ring gear and the pinion gear. Going to be using a 10/84 setup from Spike. The pinion gear hangs up on the bigger ring gear. I played around with the bolt that goes through the jackshaft. I loosened it off. I don't have a small torque wrench to measure the exact measurement. I noticed that when I tightened up the bolt that runs through the jackshaft, the pinion gear would stick or hang up on the ring gear. ( I have a manual plunger on the solenoid that I push to test the messing of the two gears.)So I have loosened off the tension on the pinion gear. Question is, is this going to cause me grief. Right now I can manually spin the pinion gear around to each tooth and then push the plunger and the gears mesh and dis-engage cleanly. Before there were some of the teeth that would stick and the gears wouldn't dis-engage when I let go of the plunger. What do you think?

@grbrown. Thanks for the reply. I hope I am understanding your question correctly. I attached the pinion onto the jackshaft and then threaded the bolt into the starter. After that I put only the clutch basket onto its' spline, to check the engagement of both sets of teeth. I did notice a wobble on the ring gear, which wasn't fully seated on the clutch basket. Took it off the bike and loosened the 6 bolts that hold it together and then used a rubber mallet to drive the ring gear onto the hub. Re-onstalled the clutch basket back on the bike. Then I engaged the pinion with the ring gear and spun it around. It engaged evenly as I spun it.
Hope that is what you are asking.
Since I don't have a small enough torque wrench, I am guessing roughly as to how tight I do the jackshaft bolt up. My thoughts would be that the bolt should be fairly snug but not real tight. My manual calls for 9-12 nm. I noticed that the tighter it got the more the pinion would bind in the ring gear. I have backed off the tension to where the locking tab is still in the grove of the jackshaft, and now when I manual engage the pinion with the push button on the end of the solenoid the pinion releases cleanly. I am not what type of torque I have applied to the jackshaft bolt. Trying to figure out if I should put the primary cover back on and put fluid in and try it.
Any suggestions would be appreciated.
TIA

Hi Scot,
I was referring to installation of the gear ring on the clutch body. I haven't done what you're doing, so was just offering a few ideas! I've read through the instructions on Spyke's website, but I don't see any way that the centering of the ring on the clutch can be altered. The jackshaft pinion should centre itself fine.
12nm is 9 lb.ft. if that helps. It isn't very much! A firm grip on a small wrench can easily exceed it. It's difficult to offer a suggestion, if you don't have or can't borrow a suitable torque wrench, however it sounds as if your reduced tightness is the solution, or darned close. Sorry I can't be any more help.
