Tires look a little overheated especially the front but unless they feel greasy I wouldn’t change anything
Click to expand...

I was experimenting with running the pressures at the upper end of the range that Pirelli recommends, I wouldn’t say they felt greasy but definitely not the rock solid confidence inspiring grip I had last track day. I was running about 25 rear and 33 front hot pressures, but today ran 27 rear and 36 to 37 front.

At 25 and 33 the grip was fantastic but the tires felt just a touch squishy for my weight and I wasn’t getting as much feel from them as I’d like, especially from the front tire…at 27/36-37 I was getting great feel but grip was a bit off for the track temps today…so the sweet spot is probably about 25.5 rear 34 front.

Were there differences in the track temp? What compound were you running?
 
You move the back down a little bit and the bike doesn't turn as well or hold a line. You're in a fast sweeper and the front runs wide. I'll try this again. Raise the fork tubes a little or move the clip-ons down the fork tubes a bit. Needs more load on the front IMHO.
 
+1 seems like your tires are getting pretty hot + 90F days, but something else is going on. Like something inconsistent. Looks like, this is a guess, they get pretty hot then cool a little, then you hammer them and they get hot again. I bet you're wearing them pretty fast.

Back at Big Willow this Saturday, pretty excited about that.

Doing some sports visualization excersizes this week.


Also, probably a ‘Too Much Information Share” here, but riding this bike is making me younger again, working out, losing weight, and getting in shape so I can ride this thing better.

52 years old and it’s getting me in shape a bit, Before tracking the Ducati and after tracking the Ducati for a year:

Does wonders when you figure out that the best upgrade you can do to go faster is to upgrade yourself 😂😂😂

DANG! Good job!
 
Did you run SC2 front on the previous time at Big Willow?

With those hotter temps, might be worth considering SC1 front with higher pressure to keep the stability. The SC2 might have better sidewall feel but the compound isn’t ideal for hot weather. Though, with hotter track temps you’ll be burning through tires rather quickly especially with your size. I’d anticipate getting just a day out of an SC1 set when it’s super hot out.

Then again, if I were running slicks I’d go w the SC3 with the aim of going slower for longer. Less hassle with tire warmers and will last multiple days. For me, trackdays are about focusing on learning the bike/oneself rather than lap times/outright performance.

If you’re racing, then throw the kitchen sink at it.

Okay night and day difference on turn in and mid corner feel with the rear hub back where it should be, bike is going exactly where I want it to and holding the line better.

Also even on this very fast track 15/41 gearing seems to deliver the power just right.

One of these days I’m going to learn to stop experimenting when the bike already feels good lol




Any thoughts on my tire wear?

More tire pressure, less tire pressure, keep it as is?

Full disclosure, this track has a pretty rough surface that’s known for eating tires.

You need to measure your ride height Steven!

A ride height tool is best, but two, fixed, reference points, will also do. 👌

You'd be surprised what big differences come, from very small adjustments.

Are you sure about this? Depends, a lot, on where the starting point is. And, we don't know which way, the rear ride height went.

If it's on its nose, and you lift the rear further, it will be harder to turn.
 
Moving the clip-ons down puts more body weight on the front. I'd raise the fork tubes a bit. Rick I'm just reading the tires. But part of that is my riding style that's what i'd do. I can't see where his set up is. You're right i could be way off base.

Might not even be ride height that’s an issue. 5 mm either way on a street bike setup is probably imperceptible. Steven, are you running the 60 or 65 AR rear? Could be as bp pointed out that the understeer could be coming from an overheated front tire
 
Moving the clip-ons down moves your mass down and forward a little. Regardless of your grip on the bars. Sometimes changing the droop of the bars changes the feel of the bike (Troy Corser). I don't hang on much and i don't run a steering damper (kills feel). If the head goes off I let the bars slap my palms. Steven take a couple of pictures of your set up. The question becomes does the bike push only in high speed corners and does it do that consistently? Does it push in mid speed corners?

No steering damper?!?! Oy vey
 
I knew that would freak you out. Damper kills feel. I don't set the front down crooked. If the bars wag when the fronts skimming the pavement who cares. I haven't owned a ducati that would amplify the head since I raced a 2 valve (front dropped 3/4 inch, rear raised 1 or so inch, pretty steep). That wouldn't amplify without being really stupid even on crap pavement. And you could catch it by letting it slap your palms. But even the cast mags were pretty heavy then. Raced a 916 without a damper for years. Steep and still rock solid. CF wheels might change that.
 
I've never seen the reason for upgraded steering dampers. The stock ones are always way more than enough. Have the damper as low as possible, or as Baggerman has it, completely off.
My damper bracket came loose in my last race. Didn't affect me. Although, I do feel it benefits, so have the stock base one.
