I've had good experience with Moss in the past. Set a couple PB's one year and went faster than I ever did at Barber with his help. Would have won a couple national championships if not for some kid named McDonough .. BTW, the level of knowledge he brings is somewhat relative to your experience. The "magic" tire wear stuff is nice, but it's still fairly generalized, given riders, bikes, etc - and of course opens up the internet world to speculation and interpretation. Work with him one on one and it's much more than that. YRMV.
So many times people get slammed for an opinion yet rarely do the slammers offer anything up as an alternative. I look at 'em like this, "Put up or shut up." With a "Put up...", at least there's a chance of meaningful discussion...or more "Your a f*ckin' dumb-ass." I guess it depends on the intelligence and maturity of the parties involved. Mostly, it seems everyone here is a dumb-ass...except Lever. He always had an alternative method.
Who is Dave Moss? Got a cool last name and if he's even a woodpile relationship to Stirling he'd be sano as all f@ck in my book.
As long as you view his and everyone else's (even Keith Code) advice as clues instead of facts, you'll be alright. Chassis tuning is shades of gray, not black and white. YouTube doesn't lend itself well to that concept. The more I learn, the less I "know".
My mind is racing, the cats are pacing. cheeseburgers are cool hambugers are just a tool until you cheese Kill metalhead please please PLEASE!
AFM can run the ambulance with bikes on track and I can remember a few times that they have done so; they might have even done so for me this month but I don't remember that part of the day The track days just simply don't. My read of it is pretty simple: the track day providers do not trust the track day riders enough. We have a tremendous number of motorcycle riders up here and there just isn't enough trust thus the stop on track, etc.
People that can't operate motorcycles are operating motorcycles. People that can assist those that can't operate motorcycles are being hampered from doing so by that same group of non-operators.
What Fred said is fairly relevant. Dave has to paint in very, very broad strokes because he's selling information in a very broad, general way because of how he's structured his business. It's like sag numbers. He has to sell a number because it's a number to sell. The only real problem arises when people take these broad strokes and try to apply fine points to them without any additional information. It happens on here and it happens on Facebook and on every motorcycle forum on the planet. You cannot definitively tune suspension based on a picture of a tire without more data points. You can, however, talk in very broad generalizations and be kinda sorta right.
Before I did motorcycles, I worked in the publishing industry while I beat on E30 BMWs. Both skillsets have been proven useful in my chosen profession. Also, I have more of the stuff you were looking for...
On another forum I got beat up pretty bad about a pic of a tire I posted. Nobody had any real answers, but kept referring to Dave Moss vids on youtube. I wrote it off as a bunch of internet jerkoffs that were heroes in their own minds.
Talk to the guy that built your suspension and is familiar with the track you race on instead of the Internet.
