Clay know's what he's doing

'Eh, I've seen what hard up/down shifts does to engagement dogs and shift forks. I'd rather replace or file down a clutch basket vs replacing gears and shift forks. I'm not on a factory bike with unlimited resources so I'll take those few tenths of a second per lap penalty.

The only time I've ever gone all clutchless up and downshifts is when I'm in a do or die battle! That was a fun race and I was pushing it, but the guys in front of me (Carlo and Walter..the one who crashed) were gone so I just needed to keep the others behind me. I've been in one race this year where I threw it all to the wind and rode with everything I had. I won the race and had a friend on a 150r on my rear tire the whole race. THAT was a fun race.

Sorry guys.... not tryin to insult anyone's riding skill or intelligence, just tryin to post some minor constructive criticism. I have a habit of trying to help people with their riding as it's something that I get paid to do on a regular basis.

Clay, this will make very little difference so I don't think we need to get too into it... but when done right (not hard), clutchless upshifting does not cause ANY accelerated wear on the transmission (certainly not the gears themselves as it's a constant mesh transmission and the gears are constantly engaged). By rolling off the throttle (or using a quickshifter device) you release the tension inside the transmission and it will click into the next gear with no added stress on the internals. And with as many upshifts as you were making in that video that's a lot of added heat on the clutch plates.

People have been doing this with constant mesh transmissions forever and it is rarely ever the cause of any issues. In fact it's even a technique that I often teach to new track riders. It's one of the many advantages of a constant mesh transmission. Why not take advantage of it?

EDIT: Anyway, this thread is about your vid. Thanks for posting, it was fun to watch.

LOL, it's all good. Everyone has their method.

Great race, Clay!

Is Walter from Miami?

If so, he is the guy that runs our local mini track. I need to get back out there.

He sure is. Fast as heck. Of course, we called him the body surfer. I think he crashed 3x in that race alone. LOL
