Anybody here familiar with both GPz750 twin shock r1 model and the later zx unitrack model?
I have a spare zx motor which I could use, I know they are more powerful with longer duration cams but I'm wondering if that is what i really want.
On the 550's, the twin shock GPz has more bottom and miidrange whereas the unitrack model is more cammy rpm power. Thrashing the nuts off a 550 to the redline is great fun and with the six speed close ratio box tuning for rpm power makes sense to me.
The 750 twinshock though has nice midrange power, I'm thinking adding a few more bhp nearer the redline at the expense of this might not be such a good deal for me for road use.
Does anyone have the factory manual dyno sheets for both?

If you have a ZX motor I'd run it.
Based on mine when stock in my KZ650 the mid range worked great on
the street and the top end charge will bring a smile to your face.
