Thanks, I realise new is the best way but with other gaskets if correctly greased before hand can be reused. The reason I was asking is that they are 7 euros plus shipping here in France. After cleaning up the bits I've spotted a small tear so it will need one anyway now.
Cheers

Just stripped the oil pump on the Gpz11 for a clean and the FSM says to replace the gasket. It is in one piece and not damaged. Do I need to replace it?
Cheers

I have some the same from a Z650 spares bike I bought, though the stamped number is different

The opinion from KZR was Z750

Excellent support and will make kits up

Couldn't really see the colortune due to sunlight but did a sync. No 2 had risen 6cm. Levelled that off with No.1 then had to bring 1/2 down 3cm to match 3/4 lifting the idle as I went to stop it stalling. I starts very well, no popping at all on choke and very steady cold or hot. Went for a quick b...

Gasket turned up yesterday so that was fitted along with RTV for cam cover halves. Chucked the tank on, prime for 20 secs, full choke, started 'quart de tour' as we say in French. Checked the temps of the downpipes and No.2 now gets as got as the rest. Tank back off tomorrow evening to redo the mixt...

Got it almost back together, all shimmed up, just waiting on a cam cover gasket.
Couldn't resist doing a compression test on No.2 140psi. much better than 50.

Mark, check your Clean Air System. On mine the vacuum solenoid is knackered and is always open regardless of how much or little vacuum is applied so the airbox is always feeding air into the exhaust. The reed valves work but the inner gasket on cyl 1/2 was broken and it was a bit of a mess in there....

Thanks for clearing that up Al.
Probably to stop the spring trying to tie itself in a knot when you put the end bolt on.

I have taken the tensioner out with the carbs still on but it was bloody difficult to get that long spring back in,it took so long I wish I had taken the carbs off!!! I have no idea how you mananged that, patience of Jobe of a very full swear box? One puzzler with the tensioner, the FSM mentions a ...

With the low seat height there is no room. Managaed to split the cam cover with the coils in place but will probably take them out anyway

Not the inlet, must have been my imagination or the reed valves are weeping along with the vacuum solenoid clean air thingy and getting back to the pipe in my gob. Anyway 1754751946315.jpg So 2 inlets are justin and 2 ,justout, his half brother. No exhausts are in tolerence with no.2 being the illeg...

Rigged something up, not very scientific and couldn't be used to do a leakdown test but a way of getting air into the cylinder. 1754497389085.jpg It was leaking but was hard to hear from where then I realised that the vac pipe for the tank tap is cyl 2. Couldn't hear anything but sticking it in my m...

Thanks Alan
