PART 1/ Upgrading the performance

Well, I just had to win this Muzzy full race exhaust I found on ebay in the USA.
First of all, they're nigh on impossible to find for the 91 and everybody pretty well knows that Muzzy was the most successful of the tuners.
Looking at the add and there is a mention that the headers came off Scott Russels race bike. Well, that I wouldn't believe, and who cares, look at the attention to detail on the stainless headers, the spring catches, just the whole set up stinks of "race". I was looking at Acropovic full systems, but at prices over 10,000kr I felt that was a bit high. A Muzzy pipe was searched for and a Muzzy pipe was found! delighted!

And here again, decided to take the step to follow in the footsteps of a guy who has a great website about his ZXRR, and his advice included finding some GSXR1000 K1/K2 front calipers and fit them to the R. This proved more difficult that I thought, these things aren't that common! But here are the ones I did find,and currently a man in a machine shop is making up the required spacers which will have them slot perfectly onto the RR stanctions.What is a real bonus is the fact that despite being 6 pots as opposed to the standard 4 pots, they weigh less and save recip mass weight of 200 grams which is indeed a bonus.As they replaced them on the following years bikes I reckon it was a cost excercise.

Here was a real lucky find! See the small seat lock next to the key: really not easy to find, but somebody in Germany decided to break a ZXR750M and sell the Lockset. That was fortunate (and expensive) but means that all the locks that were ripped and stripped on mine have donors!

Now obviously the main part of the bike which was smashed was the frame, so that had to be sourced as soon as possible. Fortunatly the K models had exactly the same frames as their standard cousin, the J model. So I looked for a J model and found a 91 J frame which is now on the way over as my brother had to buy it and once I've sent in the paperwork it will end up over here.

so far then, the shopping list hasn't really been for the parts that are 100% required...
91 Zxr J  frame (essential H101 KUD)
95 ZxrM lockset complete (essential)
97 P rocker suspension (optional)
L series 18,5 cm dog bones (race kit length apparently)
A full race Muzzy stainless exhaust (optional)
Six pot brakes (optional)

Tomorrow I should be moving the bike to it's new home which , after several months, should have it coming out the other end looking and feeling and sounding like a true SuperSport ZXR750R!
