RZ350 Power/Torque

[2steve]

I keep looking at these charts for YPVS programming clues.
The HP/Torque for an RZ350 with varying power valve settings makes it look like you should be at 100% open at 7400 rpm, (but with unknown pipes). Also, maybe, 100% closed until 6500 rpm regardless of pipes.

The Toomey pipe comparo is interesting, especially when you see what stock Canadian RZ pipes did for torque and power.

My RZ with Toomeys has this wild torque push at maybe around 7k that comes across as a pleasant surge forward with possible clutch slipping. Doesn't feel like the clutch is slipping, but sounds like the rpms are not climbing with the increased speed.

Wondering about changing the Zeel settings.

this is where i had mine, and a few people have used this and really like it. it always worked well, and i tweaked if for days on end.

My PV is set to start opening at 5000, full open around 7000.

What pipes did you have on yours, Mark?

I am running the Hasse Curve on my White RZ with FPPs with great success.

After riding this weekend, there's no doubt that the clutch slips between indicated 7000 rpm to 8000 rpm. Then the clutch hooks up fine until it's time to shift.

After the RZ is heat soaked, no more slip.

It's like the clutch is indicating that max output "coming on the pipe" is accomplished at that time.

Mark, I have your numbers programmed in. Your advance choice from 7k to 8k must be spot-on in combo with the PValve.

I might change the trans oil and see if the clutch situation improves.
