I'm having similar problems with mine (A1 rear caliper). When i pull the fluid through with my vaccuum pump, air seems to be getting in down the bleed nipple thread. Anyone know of a way of sealing the threads without blocking the oil way at the bottom? The nipple seems quite loose in the thread. Is...

54 views and no responses. Is this the problem which will stump everyone?!

So just to keep you posted, three of my new exhaust valves gave a shim size of around 220-230 so i took 0,30mm off these to get them into the 250-260 range. The valve which had no clearance, i pushed in a piece of 0,35mm shim stock after removing the 200 shim i had in there. This allowed me to rotat...

Can anyone suggest the best way to re-fit my brake pedal return spring without scratching my newly painted frame?
Just to make this quiz harder, my footrest mounting pins are seized in solid so i can't whip them out to persuade the pedal past the stop bolt bracket.
Thanks everyone!

I've just bought one of these cheap tools too. Anyone care to explain the best method of using them? Looks like you rotate engine until bucket is fully depressed, insert tool on the lip of the bucket, rotate engine backwards until cam lobe is out of the way, prise out and replace shim, rotate engine...

Yes, i got that but thanks for the warning! Does this mean that even if i only need to shorten the stem by 0,3mm or less i'll also need to trim the collets and retainer? Are they all pretty flush then, i always assumed there would be some clearance and that the underside of the bucket only touches t...

and that's what i love about this forum. So much experience of familiar problems = several different 'fixes'. If i got a shim ground to 1mm, would the cam lobe still have clearance?

Thanks for the advice. Shaving the collets and retainer seems the most straightforward option then. I only suggested 1mm as I currently have no gap and it would hopefully bring a gap back. It may need less than that to get a gap. is there a way of measuring the valve height as it sits in the head to...

Morning all. How much metal is it safe to remove from the tip of a new valve? Dropped an exhaust valve and have had the seat re-cut to remove the scar but had to take quite a bit of metal off. Have replaced with a new set of valves but have no valve gap even with a 200 shim so was going to shorten t...

so that idler gear just floats between the engine case and the generator cover on its shaft?

so to conclude this issue for anyone who may have been interested, it was a thrust washer on the starter idler gear (not even shown on Partzilla so maybe shouldn't have been on the shaft!), it was trapping the gear against the casings as was a fairly large thing. Anyone know if it should have been t...

hello.
the rear is 17 inch, 2.50
the front is 18 inch 2.50
I can take some photos but not for a day or two as they're in a mates workshop. Seem to remember they come with 'period' pirelli phantom rear and metzeller me33 front. Took me right back to my youth!

Thanks guys. I usually think i know what i'm doing but i love using the forum as there is so much experience to draw on.

Yeah, i'm replacing it anyway (like always). My concern now is that my genuine manual seems to be different to Z1Bman's.
New one hasn't arrived yet but i changed one in my other Z a few months back and had the same measuring difficulties. Engine runs fine though!

my 1000A1 didn't have the o rings around the cylinder sleeves when i stripped it and it wasn't leaking oil. I've just had a sit down after seeing that they cost 7 quid each!
I'm questioning what it is that they do now.
Any thoughts on their essentialness guys?
