Changing the IPB Race location "Will Not" change the position of the clutch basket..
Thanks for quick reply Hotrod....shot down in flames ! Back to the Drawing board.
So what does the Clutch Basket press against?
It's crazy....everything looks spot on so its hard to see something "wrong".
OK I'm going to loosen everything as mentioned before by all of you (thanks) and then do another dry fit this weekend.
If that doesn't help then I guess I have to go into the Transmission.

As Hotrod stated, it's not the IPB race. Your missing something with this puzzle.
First pic: Are you sure #30 is installed correctly? Also I think #46 can be installed backwards, but don't quote me on that. Second pic: Maybe time to pull the clutch release cover #26 on the other side to check out what Dan89FLSTC mentioned about the shaft being moved. Look at the nuts #22 (second pic), as your looking at it, the nut on the left is fastened to your mainshaft and you may see a little gap. There should be no gap. If you do go into that side of things, post a pic of what you see before doing anything else. Did you change out the pulley by chance??? Was the pulley spacer changed?? Again reaching at straws and scratching my head.
IMO I would first double check that all the starter parts are installed correctly then triple check the clutch basket (as mentioned) before going to the clutch release cover. Did you take anything apart on the clutch basket during the initial disassembly? Other than that, I got nothin.
I always thought that the taper in the splines of the shaft of the actual splines themselves, is what prevented the basket from going deeper onto the shaft.. I could be wrong though..
I will also say though that it does appear that your IPB race is getting rather close to the seal.. Either that has walked inward, which is common or your shaft has walked inward which would require removing the clutch release cover and checking the shaft position to see if it moved outward or even the bearing possibly shifted in the trap door assembly. Check for any clearance between the spacer and the bearing on the trap door side..
OK I checked and double checked the jackstarter couplings and 100% sure they are correct. The problem is that even if they were wrong the problem is the Clutch basket is too close to the Inner Primary anyway.
I will open the clutch release cover and check what Dan said..it may be where my 1/8" is missing but didnt touch anything to make that happen. Havent changed the pulley spacer but I will remove the sprocket nut and sprocket and go back to the tranny case and make sure I havent put it in wrongly.
Regards the Clutch basket I checked it all visually and nothing was out of place so not sure what more i can do to check it at this stage.
The IPB Race is new...put it in last week before taking it for the first ride when she blue a leak! I believe its correctly placed so maybe its the photo. IF its the taper of the splines on the input shaft then perhaps it is this that has somehow been pushed back towards the tranny a bit as you say? Ill see when i get to open the clutch release cover.
Thank you gents...lot of head scratching.
When installing the inner primary bearing race, how did you install it? What tool did you use to install it?
Another general question I'm asking anyone, if the mainshaft was indeed pushed in a little, would installing the pulley and pulley nut pull it back to the "normal position"? Just got me thinking so thought I would ask.
Not going to bring up cross loading of the bearings at this point as we still don't know what the issue is.
Lastly, Monchidog...man you sure come up with some good ones...

We all assumed that your IPB race was the original one.. You never stated till now that you replaced it. I'm curious as to how you replaced it? With what tools?
Edited: Sorry YD I didn't see your post because I was rereading through the entire post to see if he ever mentioned replacing the IPB.. Which he didn't till now.. I'm thinking Primitive Pete got in there with the old hammer..

Nice point Yankeedog, I actually had to cut the race off but I have the regular half circle type puller if I need it and I used that to push the new one on. Let me have another look and see whats there.
I think Ill open the clutch pulley cover in the morning as that will be a quick way to get an idea.
thanks for staying with me on this guys!!
Tell us how or show a pic of how you installed the race??? Not sure how to push the race on using the half circle type of puller. Just trying to get an idea to help problem solve.
Usually it's a piece of pipe and a special threaded rod and nut that holds the mainshaft in a fixed position while pushing on the inner primary bearing sleeve only so that no force is applied to the mainshaft. If force is applied to the mainshaft then it can move, which can cross load the bearings.
Also can possibly break the thin lip that is cast into the transmission case. That lip holds the big mainshaft bearing in the transmission on one side. If that lip is broken, trans case is trash.
Sorry my bad guys. Yes I cut the race off as it had walked and then pushed it back as you say with a tube and nut tool. Ill have to see about the lip
You mention and hope to help its not that.
the second photo is me pushing the 5th gear seal in but its the same tool.
