Moto3 Suddenly Down ~30 kph...
« on: September 08, 2017, 01:46:25 AM »
I was spending a great deal of time testing on Spa with the 12b Moto3 bike and posted a best time of 3:03xx with terminal speeds at the end of the straights of approximately 215 kph. I did a 15 lap test and most of the laps were in the 3:05 to 3:08 range with the occasional off track excursion pushing the times up to 3:13.

Today I tried a few laps on Spa with the Moto3 and the best I could manage was a 3:11 [I was pushing harder than when I did a 3:03.258] with the end of straight speed topping out at a paltry 186 kph. The bike had no pull after the bridge on the uphill straight which did not match my recollection from the above test. I did not make any changes to my set up.

I have been playing around on Misano the last few days on both the GP125Cup and Moto3 bikes. My best time earlier this evening was a 1:48.011 [Moto3] and I then switched to Spa to break things up a bit. After going so slowly I thought I would reboot my computer and then hop back on Misano with the Moto3 to see if perhaps my computer was causing the ultra slow Spa times. I lowered my PB to a 1:47.953 so all was good there but when I went back to Spa it was still slow as slow could be. Has anyone else experienced this?

That was the first thing I checked. Yesterday's wind speed was zero. Also, the speed deficit is around the entire track. There are three high speed sections where I would pull red line and they are not in the same direction. Speed was down equally in all three sections.

I made no changes to any settings between sessions.
