That's the classic problem, not sure if that's the issue with the 1190. It's annoying... as a longer stroke makes for a better street motor, while a short stroke is great for stupid high peak RPM with a crappy powerband and awful fuel economy. It seems like the obsessive focus on displacement in racing ignores many other equally important "limits" like how short the stroke can be, or how many cylinders you can have, etc. The net effect is peaky motors that drink fuel at prodigious rates trickling down to our street bikes... Which isn't the kind of bike I want for the street. Oh well, I suppose race bikes are for racing, and the racing organizations make the rules. | ||

I know for a fact that most of the DNF's of EBR bikes on both the teams were a result of valve problems from over reving, | ||

The pattern I see is the same one Ducati struggled with last year. MM ECU, new Motor, and V2's lack of RPM's to run with the I4's. After almost two years they appear to have it licked. That is NOT the problem Ducati had at all. Ducatis problem was compounded by injuries from round one at PI where Checa was injured (he was on the front row so though so they did not lack speed!). The Panigale certainly does not lack revs to run with the IL4 bikes at all, although due to WSB rules the motor cannot be as highly tuned as the IL4's so what they lack is outright power. Ducati have probably more experience with the MM ECu than any team out there and are currently running their MotoGP software on the Panigale in WSb (Team personnel were seen with a hand held 'wheeled device' conected to an ECU logging the circuit layout before the Imola round). Most of the problems Ducati have encountered with the Panigale have been due to chassis setup and the fact that the 'frameless' design works on some circuits and not on others and is extremely stiff. They are still having similar problems with vibration due to chassis stiffness but have managed to find a setup that is a good base setting. | ||

. Ducatis problem was compounded by injuries from round one at PI where Checa was injured (he was on the front row so though so they did not lack speed!). One of the issues they struggled with by their own press releases was not being able to Rev as high and make as much power as the I4s, and making up for it with a search for the right gearing. Chassis set up was THE MAJOR issue on some tracks, but I thought we were in a conversation about engines and challenges faced there.} I could see valve train being a weak link at high RPM, but that still doesn't explain the AMA trim machines being on average about 15% faster on top end than the WSb unless they are carrying SO much more weight that its an issue.

There have been so many theories and guesses about what is breaking, but more importantly, why? Sometimes it is a chicken/egg thing. Did the piston skirt fail, and take out the valves? did the valve stems pull?, retainer/keeper failure? Follower? Did it pull the wrist pin? Harmonics? Tensioner failure? Crank flex? Rod stretch? If you watch ultra high speed video of engine components in operation, the expected orderly operation is anything but orderly. Parts stretch and flex in amazing ways. | ||

Im liking the new Superbike Qualifying format. | ||
| Hughlysses |
So, any word from Cory or Larry about Road America? | ||
| Socoken |
I was thinking about riding up to Road America on Sunday from Menomonee Falls. Anyone else headed there on Sunday? | ||
| Bads1 |
Yep I will..... may be my last year though after 27. If they can't do better and get some TV coverage then I'm afraid its not worth following. Fan Choice sucks!!! | ||
| Wgnzlz |
I'm planning on riding up as well. I work in Menomonee Falls. | ||
| Crusty |
Fan Choice sucks!!! I don't know; they did a pretty good job with the Springfield Mile webcast. Last Sunday was Interesting. I had the TV showing the Indy 500 and the computer showing the Springfield Mile. I really was enjoying it. | ||
| Hughlysses |
Superbike practice underway. Live timing here: http://www.amaprolive.com/rr/ | ||
| M2typhoon |
And only 15 bikes??  | ||
| Rde48 |
Fanschoice.tv thinks Larry is on a Yamaha R1 Might as well just stick a fork in AMA racing. | ||

Ulrich accomplished more in a couple of months with his series than DMG has put together in ~2 years of running this one. Maybe he'll take the whole thing next year. So anyway, after first practice Cory 8th, Larry 9th, just ahead of Fillmore in 10th on the KTM. Interesting- Beaubier (fastest) turned a trap speed of 172.977, Cory managed 169.045, while Larry and Fillmore both turned 164.956. I'm still baffled at the EBR WSBK bikes being so much slower than their counterparts in that series. <3 MPH difference in AMA, ~15 MPH difference in WSBK. | ||

Cory spent a lot of time in pits for 1st qualifying. Said they were trying out new brake rotor. Comment was no bueno. Went back to the old at end of session. | ||
| Riohondohank |
Cory had to switch to backup bike and start from pits because the bike was dying when he would turn left on the warm up lap. | ||
| D_adams |
Pegram smoked the clutch on the start.  | ||
| Socoken |
Leaving Milwaukee around 10. Hope to see you guys there, socoken@yahoo.com if anyone wants to link up on the ride or at the race. Cheers! | ||

Cory finished 10th out of 13 bikes. The race was horrible. There is no line up what so ever. | ||
| Riohondohank |
Actually Cory finished 9th, but I agree that only 15 bikes entered in Superbike is pretty sad. Part of the cause is the economy making it difficult to get sponsors, but also DMG is doing a terrible job. I heard rumors of someone buying AMA Proracing from DMG sometime back, but guess they were just rumors. | ||

Hank, Cory must have had problems with the B bike also. I was in Canada corner and watched him go wide twice and looked over his shoulder twice as well. There was a illegal engine R1 that was as fast as the Graves bikes. The bike was 5 years old to boot. I was depressed just walking the pits. Its not anything like it was even 2 years ago. It worse year after year. Bad thing is. 45 dollars for a pass. Come on ??? Do you wanna get people to come to a series that needs help?? | ||

I don't understand how they can do such a bad job promoting. I watched a little of the flat track rebroadcast this morning, not sure where it was, but the stands were full and the field for single cylinder bikes had a full field too. Whoever is running that series seems to know how to get a crowd and a field of competitors in. | ||
| Riohondohank |
I was watching the live timing and Cory was turning respectable lap times on the B bike ( 17s and low 18s) except he must have had a moment on lap 5 when he turned a 19.8. He will be riding the B bike today that does not have the Merelli electronics that they just had on the A bike for this weekend. They have been having some teething issues with that. IMHO they should have done some testing of the electronics package with Cory riding it before bringing it to a race, but hindsight is 20/20. | ||

BTW if you haven't seen Danny Eslick's high side yesterday it is on my Facebook page. It is spectacular. https://m.facebook.com/hank.blackstock | ||

Hats off to Larry Pegram. A great and consistent effort brought him home above the middle of the start grid. Now, to pass that pesky KTM in the next race.  | ||
| Xl_cheese |
I noticed that the 1190 ebrs are doing only marginally better than the 1125rr did when it ran. Perhaps even the same considering the low racer turnout proving less competition. Seems like a lot of R&D, time, and money for little return. I wish them the best though. | ||

The whole superbike race seemed like everyone was just in a hurry to go home. After a few crashes and delays, it seemed like they just said, "to heck with it, lets just get enough laps in to call it a race and go home." At the onset of the restart, I could see the massive storm cell on its way directly toward us. It was the race teams that decided that even though the race was declared wet, they were going to run slicks instead of grooved tires, not the AMA. I dont watch a lot of racing, so it was a little stunning for me to be at the race and hear, "It looks like it is starting to sprinkle in turn 3....and four riders are down!" These guys really are running on the ragged edge. |
