RZ350 Track Day

This past weekend I finally had the opportunity to get the RZ350 out to NCBike with EvolveGT. It was good to get out and do a track day just for fun on this bike. I definitely took some good takeaways from the 3 sessions I took it out

First takeaway – I ran out of gearing on the main straight about a 1/3 of the way down at 115MPH. I was running a 17T front sprocket and 43T rear sprocket. The immediate fix is to get a 40T rear sprocket, but I am hoping to source an 18T 10mm offset front sprocket. That will give me the best longterm gear ratio adjustability. It looks like 39T rear is the smallest rear sprocket i can get for that SV650 rear wheel.

Second: The front brake mastercylinder is too big. I am currently running a Brembo RCS19. It was way too sensitive and it lacked the modulation I prefer. 612 Moto is going to help me make a final decision on what way to go. I am currently leaning towards the Brembo RCS17 Corsa Corta, but will see what Jack has to say first

Third: I was having an issue with positive engagement of the transmission while upshifting. It appears that the shift lever barely touches the exhaust at full stroke. I am hoping that is the issue with it not upshifting like it should. I’ll machine a small spacer and see what happens and go from there

I think longterm, I’ll look at designing new rearsets. Posssibly finding a set of woodcraft or vortex rearsets and then machining my own adapter/adjustment plates for the frame. The ergos arent the greatest and I get worn out pretty quickly. This will mean moving the exhaust mounts……..again. I’ll also be putting the 1″ rise clip-ons back on to see how those feel. Beyond that, I think i want to redo the seat.

The biggest surprise, was the suspension. Fast Bike Industries nailed it with the setup. I suspect as I pick up speed will need to fine tune a few things, but I had huge amounts of confidence in it right out the gate. The other was the motor. When its in the power band, its really AWESOME.
