Had another root canal treatment this morning.
 Three this month is pretty OTT  :o
Dentist sucks big time, I didn't have a problem until he started grinding on my teeth to fit crown/bridge.
Wouldn't have minded him being an arrogant asshole if he really was as good as he thinks he is.
 Found out the endodontist I got referred to who's being doing my root canals was dentist of the year though, really really good guy, takes the pain away   8)
I'm still doped up at present, have to go to work as soon as possible at least it will be a 3 hr shorter double shift then a week off so I should be able to get some work done on bikes (then I'll post pics of 'progress')

ouchers!

some dentists are real idiots... my mother had a runaround with some dentists who plain and simple did a terrible job with her fakes (she had been hit by a truck when younger and lost some teeth)...

good luck pj! cant wait to see what youve done.

Finally got round to making a shock spring compressor to remove rear springs. (never needed one previously, could just grab them, compress and remove collets or lock nuts )
It's all from scrap I had laying around, some of it is going to be modified and it will get bolted to a piece of 3/4" ply (I clamped it in vice to get shock apart)
 As usual, I made it way overcomplicated and just guessed a few sizes (to fit the stuff I had  ;D )
 Made some more fixtures to remove diaphragm cap from gas shock and removed 'air' valve to fit a puller rod





Not a good pic, the fine thread doesn't even show, will retake eventually.
 It's 7mm dia, 0.75mm pitch one end and 8 x 1.25 on the 'nut' end

I've just read this thread from the beginning (It's a pissy wet thawing night in the Garw with bugger all  to do while I wait for head bearings to arrive.)
Jeez you work to a standard PJ ........ do you have OCD ;)
Do you still have a link for those shocks?
Tidy.

 Nah, I'm just a lazy bastard
 I do it as good as possible the  first time then never touch it again  ;D

Sorry, don't have link for shocks, they were from e-bay, advertised for V-Max and similar.
 They will need a re-build as there is air in the damping side and not enough oil in there.
 The forked end is too wide and will either need shimming or a replacement made (you know what I did)
 I'm going to make a few other mods when I get time

 Haven't done as much as I would like on bikes, been working double shifts and  spent a bunch of time fixing large hole in the wall where I thought we had a water leak.
 We got charged for 38,000 gallons last month, about average family use for a YEAR.
 The busted pipe is fixed now, but I'm checking the water meter twice a day and still working on various holes

Uploaded the boring dark video of ride home from work  to You Tube.
 
Tooth is hurting, just had some ibuprofen, waiting for it to start working and needed something to take my mind off it.
Going to take a daytime video soon, may be a little less boring
 I don't have editing software so skip the first 1min10 sec.

As usual, nothing much happened even though I had big plans.
I did modify shocks and get them back together.
 Used air instead of Nitrogen just to check compression damping is working (I'll let it out and get them charged with Nitrogen next week)
Anyway, here's some pics of mods.
 Top of shock, where it mounts to frame.
 Bosses are for air-bleed/oil fill and compression damping adjuster (it's a Chines copy of something expensive)
I know why damping is shite out of the box, about 3 times more oil went in than came out  :o


 
I don't have a damping adjuster but I do have a 5mm tap (and know how to use it  :D )

 The sides of screw are a 'good' fit in counter-bore, 'o' ring will prevent any leaks.
 It made it really easy to re-build shock, put most of the oil in through 'top' (actually the bottom), built it up removed screw and let air out, added about 25cc of oil through hole


This is underneath when on bike
 

Before tightening down, the special pin tool I made.
 Couldn't find a torque spec so I used he German method (gut-en-tite)


Finished assembly, bump stop rubber is all the way down so I can find out how much travel I use


Forgot to mention, I got some Kawasaki Ninja 250 forks off eBay.
 Not sure if they are 35 or 37mm (I thought 37 but hoping 35mm)

EX250, at least the last gen are 37mm and nice little basic forks.
The actually weighed a bit less than the boat anchor 500T forks they're replacing here!
Emulators will help them immensely, working on turning up a pair this week for them.
Working on tracking down proper internal springs, the external springs are available at my local hardware store.
I don't know about your triples, but the 450/500T have juuuuust enough room to bore them for the bigger sticks.

Kawasaki EX250 forks arrived yesterday.
 36mm dia, not yet sure if I'll modify steerer, top bearing or change stem completely as it's 30mm instead of Honda 25mm.
 Got shocks gassed, won't be fitting them until Saturday afternoon at very earliest
 I thought I had posted dyno runs of the original CB378 motor but apparently not.
 Unfortunately I can't get any more dyno runs without paying full price or driving couple of hundred miles
 Here's original with too rich jetting and 2:1 exhaust I made (almost 10:1 fuel air ratio)
 Was doing some major experiments with carbs
 With jetting leaned out it should be making closer to 40bhp all the time (stock cam and carbs)
 Dotted line on lower graph is 'ideal' fuel air ratio for max power (about 13:1) you can see where power drops as it gets richer

 Here's with quiet exhaust and rich jetting, while I was still experimenting with jetting, real rich still so losing bunch of power.

Those graphs make for interesting reading.
Especially the correlation between air fuel/ratio and the power curve.

36mm huh? What years, do you know?
Just curiosity mainly, as I said...mine came from a last gen.
