Chain snapped. Came close.
« on: June 18, 2018, 04:11:14 PM »

Coming out of turn one, chain let go. Note to self, slow down a bit more before hitting the grass on purpose. It hit the tail and still came that close to me. Happy it did not hit anyone else or stay on the track. I had just inspected it before the weekend but it came on a used bike so no telling.

Looks like a scorpion's tail trying to sting you.

Wow, cool shot!

Glad it didn’t do any real damage when it let go.

Very good point. Have not bought any used sport bikes before and this bike reminds me why I was always shy to the idea. From the brakes being deadly to this I hope there is nothing else I have overlooked. I have wired about everything I can out of fear already. Got the new RK XW-ring chain on the way as it was the highest rated one I could find. And new sprockets of course. Should do the trick. Anyone have any hot laps on GoPro they care to share from last weekend? I would like to see where I suck so bad. Ha. I learned how to swim watching, so would love to see some good folks go at a track still fresh on my mind.

Red rocks thank you for sharing. As this is an often over looked and pretty neglected critical part.

We are all guilty one time or another on the chain.

I was until I saw I think Larry Pegram's chain snap going up hill to start finish at Road America and just miss Aaron Yates I believe.

I don't think people fully appreciate what can happen when a chain snaps.

-Best case you loose a chain.

-They have the force to cut a hole in your engine cases, take a swing arm apart, split a tire and wheel open. Destroy legs and feet.

I have replacement schedules on chains now and measure links pretty frequent on the big bikes once they start getting close to my limit as good as it may look and how much I want to spend $135 on something else. On goes the new chain.

Happy this did not end up worse.

Best investment I ever made was a Regina pin pusher and D.I.D. Chain rivet tool.
With the Regina you never grind a pin off again to change your chain.

Again glad you were not hurt that photo if you roll back a frame in the video I bet you see an angel on your shoulder.

Damn I am ready to get back out there.

Yeah on my 1000 I replace it early from all the dirt bike ones I’ve seen cause havoc with much weaker motors. But it never crossed my mind with it being a used bike to check the actual chain for wear. I just checked the sprockets. Won’t make that mistake twice. I’ll check that pin push tool out, sounds like a win.

I also remember Steve Rapp's chain snapping off his ZX10 at Road America - I thought of that immediately when you told me what happened to yours, Andy........sincerely glad you (and everyone behind you, of course) weren't hurt when that thing gave up the ghost

Get that new chain on and ready for the North course in a few weeks :)

Well now that I got the cover off and could inspect a lot better the sprockets are very very new. The rear had some wear but the front almost none. The damage I thought it took in the break was more cosmetic than anything. I held the front up next to the new one and it was hard to see a difference. BUT, what I did find, was that the front sprocket nut was less than finger tight and the holding screw was gone. The sprocket could move side to side a lot... chain tension was good and sprockets were good so my new theory is the chain came off the front sprocket that was able to move side to side and then snapped the chain off in the best way possible. Torqued it, added missing screw, and a tube of loctite on every thing I touched that’s not safety wired. With new sprockets and RK GXW chain. Will be checking that after every ride from now on.  :banghead:

Thanks, Ruhe, for separating me from another 160 bucks, lol.
That pin pusher is slick. Still waiting for the riveter.
