Clear road, good visibility......... ... I knew the reflash would help but didn't expect the top speed improvement........ .........
and one handed as well!

Nice! How much did the top speed improve? What did it cost??
-
Very nice
-
Stock top speed with OEM tires and gearing is ~113 mph at 7200 RPM redline. The only way a reflash would raise the top speed is by raising the redline RPM. Good luck with that!
-
It's a joke! The speedometer is reading too fast vs the rpm.
Ok, what is throwing it off? I just put the wheels with new brake rotors on today after making the rims tubeless.
I fixed it, just wondering who can guess what it was!

OK, I'll bite. If the new tires are smaller diameter than the originals, the wheels will turn faster at any given speed and the speedometer will read high.

Tires are the same size.
I am still surprised on what it was.

Non-magnetic rear rotor bolt? (stainless or titanium?)

I mixed up two of the bolts with the front wheel rotor bolts. Front bolts have a recess in the center and the rears are standard so the recessed ones were sending double pulses showing an increase in speed.

Kudos to you. That is a subtle distinction and right on the money. On the later ABS models, both wheels have slotted timing discs that provide the signals to the wheel speed sensors, but your vintage V7 takes the signal from the rear disc bolt heads. In addition to the presence or absence of dimples on their heads, the front and rear bolts have slightly different lengths, according to the parts manual, M8x20 for the front and M8x18 for the rear, but they could easily be exchanged, as you found out. Nice going.

ratguzzi, since you had your brake discs off, maybe you can answer a question I'm curious about. The parts manuals show a part, number GU32636160, called a "rubber support part", that goes under the brake disc on the rear wheel hub. This is NOT the cush rubbers that go on the other side of the wheel. I believe that there are supposed to be 6 of them under the disc, rather than 1 as the manual indicates, and that they serve as anti-squeal dampers. Also, I think they are only used on the spoked rear wheels, and not on the cast alloy ones, despite what the parts manuals indicate. The cast alloy rear wheel on my '16 Stone does not have this rubber part(s) under the disc. Can you provide any info or insight? Thanks, Sam

Sucked the gas right out of the tank!

Here's your sign .....

You are correct. The aluminum spoked wheels have the rubber behind the brake rotor and the cast wheel does not. I wish I would have taken a pic because I don't remember if one piece or multiple. I think six separate ones.
