VIDEO: Shannonville long track June 17th, 2011

Hey guys,

Well I'm back from without question one of the funnest trackdays I've ever been to at Shannonville. 25 riders total for the day. 2 groups. 250kms. Zero rain and even a free lunch! Myself, Broady, Paul and Kamper tore it up all day long, and couldn't have had a better time.

I took a TON of video with my new GoPro HD, and wanted to share one of the videos I made. I had the camera fixed on the plastic tank cover, which had a little too much vibration, so the video isn't as "good" as it could be, but you get the idea...

Enjoy,
Colin

Thanks guys, it was a great day!

There were only 25 riders there (about 12 in group 1 and 12 in group 2)... when we rode from 3pm-5pm, we were literally the only guys on the track, and that's when the sun was shinning... we really lucked out!
 
Thanks guys!

It was a Shannonville run day, it was really good. Easy going, free lunch, rain cancellation policy.... pretty impressive.
 
Looks like you over revved on the downshift down the back straight there once. Something to watch for.
 
Slipper clutch. 600 guages on a 750. You can rev the piss out of these engines all day long, slipper and rev limiter will protect the engine.

Ask Joey what happened to his R6 at Race City. You can still over rev a motor against the slipper and rev limiter. If you grab two or three gears and dump it the only thing that matters is your slip settings and wheel speed. A rev limiter that cuts spark or fuel won't limit engine speed if the rear wheel is driving it higher.

I'm not saying it isn't possible... but Joeys engines were built to the ragged edge and a ticking time bomb. In my case its an OEM slipper in a bone stock motor, I'm not worried about it at all.
 
Sure wish that I could have been there. Wasn't possible.

No valvetrain (stock motor or Miller motor) is going to tolerate 19,000rpm during a mechanically driven over rev.

Just sayin!

might want to think about that, I've seen a bunch of OEM motors go this way.

the rev limiter doesn't really work this way, the ignition coils may shut off at 1X,XXX rpm, but that doesn't mean the mechanical bits won't spin faster than this if you force them.

mechanical over-rev is far more damaging than holding your bike on the limiter under acceleration.

The OEM tachs on those things are rediculously optimistic. I have my soft limiter set to 15000, verified on the dyno, while the tach reads 16500. If Colin has a stock ECU then what you heard was happening closer to 14500, not 16xxxx.

Alright alright, I must admit, watching the play back on the video.... The b!tch was over revving quite a bit lol. I'm changing my gearing around so I can do a single down shift off the back straight.

Two downshifts is fine if you let the clutch out between them. As long as you have a long enough delay between downshifts to bring wheelspeed down to a suitable level its fine.

Or.. just go faster.

Go watch the video of you and me riding back in 09, you can hear my downshifts going from 4th to 2nd. Even last year with the new gearing i was still only grabbing two downshifts there going from 5th to 3rd.
