I think you would have been fine with just torquing them/spec or ~20% less than spec. The LokTight and lock washer seems a bit overkill but you'll be sure they won't fall out now.

I was going to suggest a dremmel to start a hole for a drill bit but you'd probably need some kind of guide to slide the bit down. Dremmels love to skip all over the place.

I think I would have done the same if I wanted to go with the chain guard. Maybe next time you change the chain you will have another whack at that busted bolt.

Nice sprocket, too! Went with the SuperSprox? Nice choice. Can't wait to see pics of the chain with the whole bike.

Works done! go out and ride!

Not the best picture but here she is all buttoned up. So excited to ride. The former sprocket lost about 7 of the 41 teeth last October and I have just been putting the project off, so I have not ridden at all this season :( . My new sprocket is a 43.


I am really proud of the rear wheel. It took about 2 hours of cleaning to get it that shiny. It was just black before.

Everybody has their own way of doing chains and sprockets so here is mine. I have a lift and air and I am old and do not enjoys working on the floor anymore. Bike goes on lift then adjust chain as tite as I dare then have some one else hold the rear brake pedal down then attack the countershaft sprocket with my 3/4 in electric impact. I use the electric because it backs out 1 ton lugnutz and if they are tuff it breaks the stud. Sucker has the power. I found out that making the chain tite and rear brake applied that there is no slack that kills impactizm. The nut get all the impact action. Next is pull rear wheel then cut off wheel to take the old chain apart. Cutoff wheels are fast. Countershaft sprocket does not always like to pop off so in that case I put the nut on the end of the countershaft threads then put a cotter key puller behind the sprocket to pry out them tap the nut with a hammer. Sometimes I have to rotate the sprocket and do the hammer tap again. Rear sprocket comes off with the impact but new one get tq'd down by tq wrench. I have a chain tool so pressing back together is not a problem. Rook had good pics of them in work.
Like I said we all have our own ways

Those are great tips, lytnin. 'specially the one about tightening the chain to use the impact. You get older, you do things smarter.

Chain and sprocket looks beautiful, viper.

So Rook, how about the update to this...
Mileage on the sprocket? When it reached the end of its serviceable life did you only replace the rear? Mileage on second sprocket if you did? Pros and cons? Worries?

I have watched this thread from its beginning and always tinkered with the idea of this gearing without ever truly considering it for a stock wheelbase. I had a 43t standard aluminum Vortex on for 21k miles (after 7k miles on the stock chain/front sprocket) and it never felt wrong or gave any questionable feedback... even after losing almost every other tooth I had to look at it to see the damage. When I pull the sprocket in the coming week or so, expect some photos.
As a curious individual and always a sucker for solid deals, I snagged a new EK ZVX3 120 link chain for $112 along with a 45 tooth Vortex in the F5 hardcoat for $24 USD (instead of $60+ for a 43t) both on Amazon.

Second sprocket and chain replacement 9 years later

SO here we are three years after my last post on this thread and I'm finally getting around to getting it done. The steel front sprocket gave me 24,000 miles of service and it could go another couple thousand, maybe. I see no need to push it to the point that it might break a tooth though. I have gone through two 45T aluminum rear sprockets with the 17T steel front Supersprox. I have used the EK ZZZ chain for the whole 24,000 miles as well. According to the ZX-14 service manual, the ZZZ is now at the max of the standard range for chain stretch. Unfortunately, I didn't measure the 21 pins before putting it into service. Sure seems like I adjusted that chain hardly at all except for when I changed sprockets. That chain mighta lasted another 25,000, IDK. Or it might have stretched to the service limit in a short time with the new sprockets I'm putting on. I've wanted a gold chain for a long time anyway so I don't mind not having to live with the old chrome one for another 7 years.

The OEM engine sprocket gave me 25,000 miles but that was all with a 41T rear. I'd say the aftermarket steel sprockets last about as good as the OEM sprocket. The aluminum rear sprockets last about half the life of a steel front and the HD chain I got----well it measured out about the same across 21 pins as the OEM chain did after approximately the same number of miles (with just the 41T on there and that probably wears everything less than the 45T I like to use now). According to my math, appears the Z3D chain is a tiny bit heavier than the ZZZ which was about the same weight as the OEM chain. I will have to verify the exact weight of the Z3D after I cut it to size though.

Vortex is the lightest rear I've used. I hear Renthal is lighter yet. I got a Driven this time and it is a bit lighter than the AFAM I last had on there.

Vortex 17T steel front is lighter than the 17T steel Supersprox I will be removing.

Pics on all of this to come.

Looks like time to change.

MAJOR ALERT!
You know that safety retainer washer you bend up to lock the countershaft sprocket nut? Ever wonder if it is necessary? Well it is. I got the washer bent flat, barred the wheel and got the breaker bar on there. The nut spun right loose with no effort at all. I did try the socket fit on there by hand first so the nut wasn't totally loose but I doubt it was even hand tight. The safety washer was what held that thing on.

BS on the notion that the countershaft rotation tends to keep the nut tight. It didn't for me. I did reuse the nut rather than replace...could that have been it? Glad I decided not to skip that washer or I'da been toast at some point in the past 9 years. No damper or steel plate in the sprocket cover either.

USE THE WASHER!

BTW, the old EK chain came off without much trouble. The hollow tipped pins in the master link grind away a lot quicker than a solid rivet. It laughed at a cobalt drill bit though. The master link pin presses out with a chain breaker just like the other links do.

I'll show pics whenever the forum starts letting me upload pics again. No worky at the moment.
