Potential solution for CCT - need help!

Potential solution for CCT - need help!
Fellow Hawkers and Stormers, looking for help.
I know it sound a bit off-topic, but I am looking for owners of Kawasaki ZX11 or ZZR1100 - I desperately need somebody to get measurements of cam chan tensioner. I need basically 3 measurements, but understand that nobody probably will want to unbolt CCT just for that, so - at least measurements of part of it that outside engine will be great help.
Here is some details from man on KZ site (where idea comes from)
http://tech.zn1300.com/cam-chain-tensioner.html
I need:
distance between mounting bolts
diameter of part that sticks out
and - only if you happen to have your Kawi engine out or just old CCT hanging around - diameter of that part of CCT that goes into engine and max-min lenght of CCT part that goes inside engine....
I am trying to sort once forever infamous HOnda CCT issue on Storm to avoid potential trouble...so Kawi CCT will do if size allows....
Here is the photo to see what I mean:

Re: Potential solution for CCT - need help!
Following some of my previous posts - yesterday I have installed Kawasaki CCT on rear cylinder of my Storm.
It took about 30 minutes to mark new fixation holes (3 mm offset from original, 34 mm between new holes and slightly offset to side against centerline) and I guess it will take another 15 min to make new gasket, as I tried it with just sealant just to stop oil leaking....
I did not rode bike, but I did run engine and saw no probs.
What's the gain - Kawa CCT comes in positive ratchet design - it has usual compression spring and ratchet rod that can only go one way - extending.
You can see it on photos.
2 things left to verify:
1. Will be there ay oil leaking from gasket, because kawa CCT's base a bit narrower and at one place only covers 2 mm of Honda CCT seat on cylinder. I guess that's no worry, as carter on 4 strokes ventilated and should not keep such serious pressure that 2 mm wide (in one spot) gasket would not hold.
2. My bike got 32 000 km on the clock. Kawa CCT a bit shorter when fully extended than Honda one (for Honda I am talking about "useful" movement supported by full spring pressure). After I installed Kawa CCT and put spring in I then run engine and then took spring and CCT out to see how much throw left in CCT - when I pulled rod it came out another 5 mm. So, it got 5 mm more to move guide, which as per my calculation means about 7.5 mm movement of top end of chain guide but overall let take out aboout good 20-25 mm of slack in chain. Of course, there is an easy way to give it EXACT throw of Honda CCT - for example as Tony suggested by making a weld blub on end of rod, but as I have limited access to any workshops - all, what do you think - does CCT need more than 5 mm throw left to take care of chain wear or it is good enough?
Looking for advice on that one - any ideas?
To see what I mean check out engine cut kindly posted by somebody in gallery:

So, either way - it seems to sort issue, and suprisingly as I went for Kawa CCT to multi-brands dealership where guys also run a workshop for all makes - they say they've done it in past to some Storm, but it was while ago. Mechanic said - because they thought Honda has updated CCT with new spring it is not a problem anymore, they never came back to that solution....
I did not really ride bike with mod yet - need to get gasket done, otherwise it will probably "sweat" oil....
Spring force on Kawa CCT appeares almost equal (a tad more) than on Honda CCT, but bearing in mind that ALL honda CB and VT series absolutely equal - I doubt such small deviation if tension force will make any difference.
If you want to give it a try - all Kawasaki ZZR, ZX,Z series CCTs same.
Mine was quite expensive (wrong place to buy), but normally I'd expect it to be around 50 GBP.
Good proof of how reliable it is - out of ALL belgium dealers only 1 had spare CCT in stock and only 1 CCT, that part was on shelf for about 4 years!!!
I apologise if this post affect any of your ideas about CCT - I really just want to help (of course help to myself first of all ), and I realise that it might be not best solution, but it seems to work for me. Of course I will ride bike ASAP and then wil take CCT out to check if all OK.
Here is photos - quite self-explanatory.
