My Z900 A4 Rebuild

[Taffus]

Have you checked that your meter is working correctly?

Well, ordered a new reg/rec unit from Z-power today, figured after reading a lot of threads it's not worth the risk of frying something else, so as much as it hurt the wallet I reckon it could save me grief and money down the line.

By the way, thanks to everyone for comments on the bike, it's appreciated.

Davy, the bikes is where it's all goin, an that's that, even this weekends beer money , but it'll be worth it I reckon when it's on the road, and less of the redneck, I'm not from banjo country... although I would pick it over Derry even if I was

Hey I resent that remark....some of my neighbours are banjo players

It gets pretty wild out here in the wesht, although I am more cultured than cultchie

[Taffus]

I know I'm safe Davey....you wouldn't be able to make it to Clare without getting lost and turning back

Nice piece of kit should be arriving for me next week, I got hold of a lovely Metmachex deep baced swingarm for the Z , I will stick up new pics of the bike when it's all fitted and back togather.

I know I've come late to this thread . but the bike looks a cracker .
Is the caliper still sticking?
Was it rebuilt with new seals when you changed from single caliper in front to twin calipers behind?
If so ( I was thinking) did you get all the crud out of the piston seal's groove? If you didn't , the seal will grip the piston too tight. Hydraulic pressure when braking will be enough to move it out , but the normal elasticity that the seal has ( which usually retracts the piston a fraction when you let go the brakes . and lets the pads loosen the grip on the disc ) is lost. Result - binding brake .
A collapsed hydraulic hose inner lining does the same thing ( on old , old , hoses), you can tell cos the piston goes in easily once you slacken the bleed nipple in these cases .But your hoses look new.
I find that an Allen key , held in Mole grips allows you to get a good , sharp clearout of the seal's groove without rounding off it's edges. I can't remember if it's a 2 mm Allen key or what. Grip the long arm of the key with the grips , if you grip the key far enough down its length you don't even damage the key's working end. Gives a nice . clean , sharp cutting edge with a square profile and the 90 degrees sets into the groove
Is this the sign of decades of Zed bodging??

My sympathies to you - I've just rebuilt my Z9 too -see the NW200 thread.

Hi Gray, jesus mate, I had a read through that NW200 thread, you had a bad run of it sorry to read about the accident, (do'nt get me started on gravel and potholes ) but good to know yerself an the bike were repairable.
I have since completely re-stripped and rebuilt the calipers ( new seals this time) and they are currently on the shelf in the shed, before the strip the left one was completely seized and would not retract no matter what, but they seem A1 now.
I wonder will I get this bike on the road at all in the near future
As soon as I get the new bits and bobs Which I am currently waiting for fitted, I will stick on some updated pics.
