The Friendship Bike - NobleHops restores a 75 Z1

OK, on to the oil pump.

Was definitely locktited prior, was afraid I'd break a screw. Heated them up for a bit...

Presto:

Measured those clearances - they were fine. Slighly worn over the spec of normal, halfway to the service limit. No problem.

Dirty screen!

Cleaned it

Chased those threads and wire-wheeled the screws of the residual locktite:

Awaiting a gasket, and perhaps lapping of the gasket surface - is that the recommended treatment before reassembly Steve?

Case bolts, freshly replated, waiting for my gaskets and seals, more patiently than I.

That's a early style pump. It's the good kind. I have one but it was too rusty. Take the gasket off gently and show a pic. That's the part I sanded with # 600 paper on a sheet of glass. My oil pressure is great, maybe too good.

OK lads, next question for some input - the clutch springs are at the service limit. Am replacing the fibers and will glass bead the steels before reassembly, and so these need replacement too. What's the consensus for replacement? OEM or something more robust? Recall that this is a 1075 or so, running Dyna ignition, and so mildly hot-rodded.

TIA for your thoughts.

I run stock and never had a clutch slip. I go through cables too fast though. Stiffer ones? I don't think so. :dry:

I still have my original clutch & springs in my 1980 LTD 1000, with a 1075 kit, RS 34s ported head & Dyna 2000, although I don't beat on my bikes like I used to when I was younger
most aftermarket clutches wont last as long as OEM clutches
I've heard Barnett clutches & springs are pretty good quality if you want an aftermarket

Barnett has heavy duty clutch cables for less that 20.00

as for the bucket.
i would mic the o.d. of the bucket and measure the bore and find out which one doesn't measure out like the other buckets and bores.
then depending on what i found would determine my next step.
