Front sprocket wear. Normal for 13k km?


Recommended Posts

So, after reading all of this, decided to take a look at 14K Miles. I do see a little side wear. I checked the alignment with the Motion Pro tool about a year ago and thought it looked ok. I'm a little new to the street side, been on the dirt side for long years. Is it time for a change? I usually change everything as a set. I always buy upper end chains and sprocket. So 

1. Good for a while more or time to change. 

2. I have order started are Rocky MT, any suggestion on chain and sprockets?

3. What is your favorite chain rivet tool? 

4. what is the chain rivet tool you hate and never buy again. 

Thanks, and Happy New Year

Not too bad for the stock chain.  Are there any binding, stiff links that kink?  If so, no amount of lube will free them, so replacement is needed sooner than later...

Check out Sprocket Center, and their 520 conversion kits.

Motion Pro's PBR or DIDs but whoever's you get you want one that mushrooms AND quad stakes the ML pins. You need a digital veneer caliper to measure mushroom diameter.  I use a mini grinder to remove the old pin head and an ancient chain breaker to drive out the pin because they're faster and easier.

Thanks for the reply, chain seems to be in great shape, I keep it sprayed with chain wax and some thicker lube on the rollers. Degrease about every fourth lubing with o ring friendly degreaser.
