Don, you officially win most posts of all time in a given time span. Not sure what the prize is but you sir are the clear winner. So according to Cycler, that bike with the custom exhaust you posted isn’t really yours is this accurate? I guess it doesn’t matter as long as it’s your bike in your mind. Anyhoooo, please school all of us on the primary and secondary clutch springs in the V4 clutch. You know give us the “trick” setup chief.

.... I am gone for 3 days and Don14 has tripled his posts from a week ago pretty clear he has gone bonkers. Sure pretty obvious way too much talk to even put a couple parts on a bike let alone building a bike. Primary or secondary clutch springs WTF which planet is he on? Absolute horror show hope all these new guys on the board are not taking notes from Don yeah pay attention folks could get messy.

Aaron is a genius. How did he figure out that’s not my bike? The exhaust is mocked up on a RS. I do not own a RS. Never claimed the bike was mine. Show me where I said anything remotely close to that. You both are too much. Aaron burnt me. Plain n simple
Yeah I have some ideas for the clutch. I’m a clutch guy. Motor carbs trans as well. I designed the lock up clutch that mtc now sells as gen2. It’s in every NHRA pro stock bike and used in a bunch of other classes too. Who gives a ....? I asked a simple question about what weight springs he is going to try first. Cuz that’s what this thread is about. His bike and his experience with it
So which springs did it come with Karl?

KarlKani, is this the EVO master? What ratio are you running? I ask because I’ve been told the 30mm pistons on the MS calipers can limit which masters are best used.
Front calipers and brake master finally arrived

This is XA7G7G0 - I believe the evo is maybe slightly newer iteration? This is 19x18 yes the pistons in caliper are all 30mm. You can use 17 or 19 master - and that whole discussion is a can of worms I know. I will try this one if I don’t like the feeling I will go 17

Yeah. The 18x18 evo is XA7G750. I’m curious if there are really any differences between the two series, aside from ratios. It looks as though they are offered in 17, 18, and 19 piston diameter, but with a constant 18 ratio between sizes.
Hmmmmm. Decisions decisions.

I think they have smaller levers? Other than that I don't know Brembo product line is always a little confusing

Cost to power/weight thing we were talking about:
Short answer GP21 has 234 to +250hp with $4million build cost @ 346.1 lbs.dry weight
Anyway, KarlKani, if you find 300hp in all your mods and you don't go faster than Miller, then we're all going to razz you endlessly.
No pressure. ;P
However if you find 300hp with less than $7figures you will be our mods-king and we will buy your signed books.
No pressure.
The googles say, "www.ducati.com › racing › motogp
234 hp with full racing exhaust Power · 87.7 lb-ft with full racing exhaust Torque · 152.2 kg (335.5 lb) with racing kit Dry weight."
Each prototype will vary of corse.
Ducati.com GP21 Tech Specs section says, "Over 250" whatever that is. That's prolly considered strategic info. For sure go fast has a lot to do with all that finesse that is going around curves with that power. But ya, it's endlessly fascinating to nerd out on the tech specs.
Money Inc has an article on the price of the 2020 bikes:
"A MotoGP 1000 cc $4 million. The engine parts alone are $425,000 with $25,000 in valuable parts, $15,000 for the tires, a range between $25,000 to $100,000 for the accident cost." This does not cover R&D costs which is usually billed to "Marketing" with its typical fuzzy budget.

Great thread. I appreciate the enthusiasm, drive, and focus to details. I'm 100% amateur and wasn't even aware of most of what is being discussed. I imagine that I'm not the only one that would be in that category. You've probably forgotten more than I know on these subjects.
Thanks for all that have contributed.

Not sure were you are getting the idea I am trying to get wsbk or gp level hp. I am not... I am tuning a V4R with full Akra system on VP T4. It should be just over 200hp at the wheel.
There is no way a GP bike makes 234 - 250+. Also think about that 250+, they have to say something and this is what they say. As I stated previously the HSBK MA V4RS makes 255 at the wheel. Those money figures are wonky also - 15k in tires? 25k in "valuable" parts? the forks cost more then 25K, tire allocation for race weekend is 22 tires, testing is crazier 12-18 tires a day. That is conservatively well over 15k in a matter of days...
Wow [mention]KarlKani [/mention] exceptional build! I cant wait to see the final product. I’ll have to come back for a Club Moto day just to see it in person. I love every part you chose and the fact that you did it on an R. The perfect motor to do this build on. Absolutely amazing! Also love the simplicity and colors of the graphics, great choice.

What I'm getting at - I'm just joking with you. 200hp at the wheel is in the 'enough' category for me hahaha.
GP bikes: I heard numbers more like $12million per bike cost. But Honda and Ducati are on different planets for budget. You might be right and they're just throwing numbers out there. This is pretty strategic info about the next year, so, maybe it's a mystery.

Who is bolting all those parts on?
I always tripped on the guys that were like, “l just ride it man”
Maybe it is a benefit to not have to think - is this right is that right maybe I shoulda done etc etc instead

I do plenty of work on my bikes, but when it comes to setting up the full build of a race bike I leave that to professionals. I cannot afford lose time on track over a stupid mistake.
