Some track day prep questions

The pressure forces the bubbles up and the port is open to the reservoir so the bubbles go into the reservoir. If there's a lot of air in the clutch bleed it first then tie it off. Tie the brake off and occasionally tap the calipers to dislodge any bubbles with a plastic mallet. Just make it a habit. You'll see.

That worked thanks.
 
2:30… FFS.

The instructor was mostly positive but said I could carry more corner speed with more lean and it would let me turn the bike tighter and so make the corner shorter and the straight longer. Makes sense.

Turn 1 he reckoned I could add 5-10kph more but with more lean.

Last turn I can carry more speed even with the current lean angle and get on the throttle harder to take me all the way to the outside of the track. This I was already aware of.

Lines were apparently good. Often turning in fractionally after my turn in point but getting to the apex.

It’s apparently time for me to get my knee down again. It’s been getting on for 30 years since I last did that… On the video I wasn’t sticking my knee out much at all and it was fairly close to the ground – just turning the knee out a fraction would’ve done it. Whilst it doesn’t bother me, he said it will give me some confidence in leaning the bike more as I will know where I am and that makes sense.

So it was an improvement again, but still not where I think I should be.

What everyone seems to forget is that tires at speed are always working thru a slip angle. Faster you go, the looser you're running the more you have to compensate for the slip angle by turning in earlier. Becomes muscle memory after awhile.

This is bc you’re relying way too much much on the bike to take that time. But the key thing is if you’re feeling more confident on the bike. Don’t worry about the times. Put the bike in low power mode and work individual corners until you’re dragging a knee and really comfortable with things. Then ramp up the power and repeat

Kenny Roberts, run it in deep, snap it onto it side, stand it up and spank everyone on the drive. The master.
 
It’s interesting to note that my maximum lean angle for this weekend is consistently about 10 degrees less than the lean angle I was consistently getting before I was trying to off the bike more. I therefore know for a fact that I can carry a lot more lean and it’s just a mental barrier to overcome.

The data logger that I installed is really useful. Seeing the lines you’ve taken over a Google map and seeing if you’ve hit your braking and turn-in markers, etc, helps to support (or not) what I feel is happening and also what the instructor tells me. As an example, seeing how long it took me to get to 100% throttle on the last turn and how much room I had on the outside of the track to do it much sooner. Obviously not deep-dive stuff - that would be pointless - but for general stuff it’s useful.
 
One funny thing from the instructor - I mentioned that I wasn’t bringing my progress from Most to Brno. He pointed out some basic maths and that I should be looking at the percentage difference from the lap record and not the time difference as they are very different length tracks… Blindingly obvious. 🫣

I’m marginally doing better at Brno but it’s broadly the same between the circuits. 🫣 🤣

Can’t wait for Brno again in a couple of weeks.
 
Also… does this seem a bit low (suspension travel indicator) or is it about right:
