This is why I will NEVER buy another aluminum sprocket

Happened sometime Monday afternoon at Pueblo. Hit a false neutral between 3rd and 4th gear at redline when powering down the back straight. Clutched it back into 4th, hammered the throttle, and it took all 47 teeth in a nice, jerking, domino effect.

Chris, for what your doing, you shouldn't need a lighter sprocket..The original one would work just fine..

Yeah that pic was a lil scary when i got it on my phone, that looks even WORSE than I thought tho...
WOW.
Glad ur ok otherwise.

Agreed.

I guess the problem started well before Pueblo. My brother (ever so kindly) pointed out to me AFTER the fact that my sprocket's teeth were looking a little funny. "Yeah man, I knew you were going to have a problem with that thing sooner or later. Those teeth looked pretty bad."

:wallbash:

oh ;) thanks a LOT bro...ya prick lol

Look at Stealth sprockets. Aluminum center with a hardened steel outer ring for durability, yet lighter than an all steel sprocket :)

You still don't have that fixed!?!?! What's wrong with you??? you know there's still good riding days left, right?

[Aracheon]

The bike is completely torn apart now, heh.

I blew a fork seal at PMI also, and after spending a good 45 minutes on Tuesday morning trying to get the suspension adjusted, it became evidently clear that it's too tired for safe track use at 29,000mi. It's time to give her a break while I get everything fixed and replaced. :)

Thought about ahhh.. buying a decent brand alim sprocket? :D

I have never in my life seen that? I've raced for years, and never seen that! Hell we have cut teeth off the sprocket to reduce the friction, and rotating mass. J?ust a question? do you replace both the drive sprocket, the rear sprocket, and the chain? I've seen bad things happen using new, and old parts. I went to a 520 chain from EK, and JT sprockets. I'm sure you know how to adjust a chain. So beyond that I'm lost?

I still have no idea how it happened - but no matter, it's being replaced with a steel sprocket. The rotating mass won't make THAT much of a difference.

Yes - I replaced both sprockets and the chain, as I went from the stock (530?) setup down to a 520. This time around, all 3 components will be replaced at the same time. I too have heard that using old parts with new is a bad idea, and it makes perfect sense to me. For the $100 I'd be saving, it's simply not worth it.

Yes - I know how to adjust a chain. The tension was perfect - not too tight, not too loose; independently confirmed by a pro racer and his mechanic, and 2 other novice riders as well.

No big deal, though. These particular parts are cheap.

that's the most fragged sprok I've ever seen
