foxtrot722 Posted December 30, 2021 Share Posted December 30, 2021 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 1970 DT-250 / 1972 250MX / 1973 360MX / 1974 250MX & 1974 CZ 400 Red Frame & SC 500 / 1978 YZ 250 / 1979 YZ250 / (2) 1980 YZ 250 / 1986 YZ 490 / 1989 YZ250 WR / 1994 YZ 250 / (2) 2002 YZ 426 / 2007 YZ 450 / 2007 DR 650, 2015 FJ 09 / 2020 YZ 250 Link to comment Share on other sites More sharing options...
Premium Member 2and3cylinders Posted December 31, 2021 Premium Member Share Posted December 31, 2021 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. https://www.motionpro.com/c/chain-breaker-tools Link to comment Share on other sites More sharing options...
foxtrot722 Posted December 31, 2021 Share Posted December 31, 2021 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. 1970 DT-250 / 1972 250MX / 1973 360MX / 1974 250MX & 1974 CZ 400 Red Frame & SC 500 / 1978 YZ 250 / 1979 YZ250 / (2) 1980 YZ 250 / 1986 YZ 490 / 1989 YZ250 WR / 1994 YZ 250 / (2) 2002 YZ 426 / 2007 YZ 450 / 2007 DR 650, 2015 FJ 09 / 2020 YZ 250 Link to comment Share on other sites More sharing options...
