Alternator rotor for Z1R

23 Dec 2013 06:01

My alternator rotor that is located on the left hand side of the crankshaft is starting the come loose on the shaft pivot. I believe this a common problem (especially over 206Kkms). Anyway the OEM appears to be obsolete but there is a replacement that looks like a machined housing and is cheaper.
Has anyone used one of these before? if so, what do you think of it?

Both of those appear to be the same part number.
1980 KZ1000 LTD-B4(MK II engine) - Progressive suspension, MTC pistons, Dynojet Stage III, all wear items replaced, WFO paint scheme(1978), etc..

Past bikes- 2 1976 Kz900's, 5 1975-76 Honda CB750's, Honda 500 -4, Honda 250, Honda 125, Honda 100, Suzuki RM 250, Honda XL350, Kawasaki KLR 650, etc..

is this for 1978 Z1R or 1980 ? I believe 1978 took early small taper version and 1980 took later large taper version I am pretty sure I have a couple of the early version small taper if you are in need.

DFIGPZ - Sorry, just got back from my holidays, I have the 1978 model. Joe Hooper from Pitstop has someone helping me so with some luck I should be able to find an original replacement. Thankyou for the offer.

I have several good, used ones... You'll need to lap them on the shaft, first for a good fit. I remove the dowel key and spin them with a little valve compound. Once the area is gray, rinse with brake clean and reinstall the rotor and the key. The "73-78 is the same and pretty much are indestructable, unless they get loose.
