Been out.....and made it back in one piece....stuff to note.
1. I forgot how comfortable and responsive it was! 2. I forgot even more how much i love the exhaust note....including the massive backfire i can get it to do on command...none of this burbling and popping (Chris at cjs says "popping on the overrun is just a badly fueled engine or if you want it to do that - wasted fuel") Normal even spirited riding no burbling on the overrun but, if i snap the throttle off then ill get one massive one (which i must confess i do like!) 3. I cant tell how it handles yet as i went a couple of goes round the block just to make sure nothing fell off! or was too loose etc etc. Took some tools out with me also. Bars and levers needed adjustment. I think ive got some air in the front brakes or, its just where the discs are bedding in - braking isnt brilliant so it could be either of the two. Also, the top yoke needed tightening up so i couldnt go that made as well.
Back in, took the clocks and top yoke off to knock the top locking rounds a quarter of a turn to tighten the steering up. Ill be on it tomorrow to go to work....its been the longest ive been without riding it ever so need to re-learn the handling a little - moreso with the new forks, but, on the whole it was absolutely worth it.
Oh yeah - while i was out i got a massive knock on the rear (never saw what it was but initially i thought "uh oh - what did i forget to tighten!!) - must have hit a big stone or something in the road as right at the end of the swingarm theres now a nice big scuff! - pisser.....never mind...

Certainly is.! Although in about 3k (or less) its gonna need its valve check and dare i say it, a throttle body balance. Just tossing up whether to buy the guages and do it myself (something ive always wanted to learn how to do....

I just saw your latest video on youtube. The reason you had to pry your forks apart previous was because your wheels are more than likely for a 3rd gen Z, with the non-BPF forks.
The 3rd gen uses a 100% identical wheel as the 4th gen, however the 3rd gen uses a 15.5mm wheel space on each side, while the 4th gen uses a 13mm spacer on each side of the wheel. You have to shave off 2.5mm off the 3rd gen spacers in order to fit the wheels within the forks of a 4th gen. Which seems like is what you have done, except it looks like you've only done it on one side, which could be the reason your discs didn't line up to the calipers evenly
Prying your forks apart is generally not ideal as it causes the forks to no longer be perfectly parallel, which then causes bushing wear and stiction as it goes through it's stroke. Normally there should be a small, maybe 0.5-1mm gap around the right spacer (throttle side) and right fork leg after you put the axle in and tighten it down, then you use the pinch bolts to lock it in in that position so that your forks are perfectly parallel and have completely free movement without any stiction.
Sorry, don't mean to sound preachy, just that when racing we go to ridiculous (some would say OCD) lengths to make sure that our forks are perfectly parallel, otherwise you end up with unpredictable handling at the extreme.

Thats fine but, as i say ive cured the problem now....more to the point, i bought them as Gen4 wheels so, its marchesini that have supplied the wrong spacers....ill probably give them a shout and see if i can get the right ones. Thanks for the info all the same.

Poped over to Bristol today to get help from someone I'm regarding as a friend,as only a friend would be so willing to help someone,so willingly. First may I say a big thank you,but to report on the work he has done on that phoenix,as I call it. All I can say,seeing it in the flesh,it's very impressive,the wheels are like black glass,I want those front forks,very gelouse and the work he has done in general is nothing short of awesome... Well done Comphysofa it was nice to see u pull up on it,and how chuffed,u were. And how In Ore I was at what I was looking at,loved it she's owsome.... Totally made up for u,very nice bike bud....

Just tossing up whether to buy the guages and do it myself (something ive always wanted to learn how to do.... When bikes had carbs and before FI,I always used to use mercury gauges to balance them. A pretty easy job at the time. I wonder if it's roughly the same principle with throttle bodies?

TBH im not sure - theyre still on the stock settings, ive gone to work on it and not much more. Ive played around with the compression and rebound ( a couple of clicks either way ) which has made a difference. Im full on with a back garden landscaping job which is taking up all my spare time. Just finished 12 days of digging a big hole and tomorrow starting electrical work...plan is, to get to a suspension tuner for a proper setup....just having the time to get there..!
First impressions are good, very good, feels plush (but a little hard at the moment ) but thats the stock settings i think...another thing i have to do is drop the forks through the yokes just a little as i cant get a ring spanner over the preload adjusters....gonna do that later on....

If they were valved properly for your weight and riding style by Nitron prior to you receiving them, then the clicker being in the middle of their range should be the most optimal setting for you. The majority of your dampening should be coming through your shim stacks, which should be customized to your exact specifics prior to installing the cartridge. The clickers are merely a dumb "bypass valve" that adds or removes dampening on top of what is already provided by the shim stack. Because clickers are a basic constant rate orifice restriction and not custom tuned variable flow restriction that the shim stacks are, you really want your shim stack to be dialed in perfectly and only really touch the clickers from the middle position for varying ride conditions, as needed. If you constantly have the clicker cranked far ways in either directions then that means you need to redo your shim stack. On stock suspension you will sometimes need to play with the clickers quite a bit to get a good setting that's appropriate for you, but that is because the shim stack in the stock suspension is set up in a way that's very safe and generic. On aftermarket suspension that's correctly valved for you, the middle setting should have you right in the ballpark. This is why a lot of people just end up revalving their stock forks/shocks rather than going full aftermarket. It gets you 70% of the same effect as full cartridge kit but at 50% of the cost. EDIT: perhaps there's a different name for it in the UK, but by shim stack I'm referring to the main valve attached to the damping rods which has a stack of discs that are added on top a flow valve in order to get a dynamic flow characteristic out of it.

Well, i would say maybe a little bit of adjustment. I gave my weight based on me standing on the scales with my holding my full racing leathers and boots. Ive got held leathers which are notoriously heavy but i wanted the weight based on those as if im going out pushing it im going to have a full set of leathers on. Additionally, if i would be at the tt out of all of us im usually the "bagman" so ive got the munchies, cameras, backup batteries and tools. So, if im just riding to work im going to be a bit lighter.....
Gonna try to get to dropping the forks today, but, ive got my car to wash and more digging in the garden (ive got a huge landscaping project going on as well at the moment.)!!
