GPZ1100B2 camshafts
Posted: Thu Nov 19, 2020 4:51 pm
Hi men
as you know I restored a GPZ1100 B2 a few months ago. It has a Uni-Trac (ZX1100) engine.
A few weeks ago I was able to buy a B2 engine but the camshafts are missing.
I have two spare ZX camshafts.
I wonder if I could use the ZX1100 camshafts in the B2 head. The lobes of the ZX are approx. 0,65 mm higher and they have a ratio of 300 °. The cams of a B2 have a 288° ratio.
The B2 valves have shims above the buckets and the ZX valves have shims under the bucket.
If I could use the ZX camshafts in the B2 head I plan to swap the ZX engine in my B2 for the correct one.
Is there anyone who can give correct advice?
Thanks anyway
