Extreme pre-race last minute panic weekend

The Extreme Performance Bike weekend is nearly here, and normally with 2 days to go I'd be mostly ready, but its snook up on me and the bike still needs the clutch putting back in and all the tools and stuff sorting out. Chances are I'll not get chance to sort everything as I'm busy the next couple of days.
I do have a brand new clutch pack waiting to go in, the plates have been soaking in oil for a couple of days, the pack has been measured and calculations made to determine the installed height. However i need longer standoffs for the Lockup or it wont have sufficient air gap and the lever won't have enough play to disengage the clutch. I bought some ally bar off eBay a week ago to make some but it's not arrived. So it looks like I'll have to use a couple of washers on each one to bring the height up.
I didn't have the right combination of springs and shims to get the correct spring pressure either. 6 springs and no shims will give over 200lb, which is probably too much, and 4 springs with shims only gives 156lb which probably isn't enough. So i followed up a tip i had to try using inner valve springs ...... they ain't as large as clutch springs but they do fit fine, and they offer about half the pressure. So using a combination of 4 clutch springs and 2 valve springs I'll have a base pressure that's somewhere in the region I'm after for the first run.
Wheely bars have been modified, 1/2" was chopped out of the top rail and welded back up. This will bring the bars up by quite a lot but i can wind them down to the same height as before with the adjusters. I don't know what the ideal height is so i'll just make them a bit higher than before.

The entry list for comp bike at this event is larger than ever with 11 bikes. It means that 3 bikes won't qualify. And if i don't make the field i won't get to run on the Sunday..... or at least not in Comp bike. However - both days are also a RWYB so i'll enter that on sunday if i'm not in the field. I may enter it anyway just to get more runs in!
