use a 8mm allen bolt coated in some fine grinding paste & wd 40 & work it gently until the new bolt screws in by hand also fit a schnorr washer under the bolt

its a possibility the fork is slightly bent

personally i would say the spacer is too short or not correct for the bike pictures would be a help ?

this is a z900a4 spindle & nuts https://www.ebay.co.uk/i/331834749822?chn=ps&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=331834749822&targetid=938148484496&device=c&mktype=pla&googleloc=1006564&poi=&campaignid=10199630638&mkgroupid=10...

when fully tightened the 2 x 27mm axle nuts do not clamp against the outside surface of the lower fork leg there is a gap. make sure you speedo drive & spacer are flush against the inside surface of the lower fork legs

set the clearances closer to the maximum rather than the minimum

4mm end float it a lot its either the roller bearing on the shaft or the washer behind the clutch is missing

personally i would leave the sump of & i would remove the cams & cam buckets & flush the oil ways through first before you re assemble also remove the pump & check the oil pump gears with feeler gauges as per genuine workshop manual

just tap them in with a hammer as long as use tap them in square they will be fine

if you look at the part no's it lists 4 of all the mounting parts

z900a4 steering stops are different the stop on the frame is welded in front of the lower bearing seating on the frame . the z1 stop is a round peg welded to the frame bracing between the front frame tubes
