Replaced my chain yesterday. My old one was at the end of adjustment and had several kinks. Went with DID chain and Esjot sprockets. The right tool helps so I used a Motion Pro Jumbo chain tool (thanks Speedwerks). The chain I bought had 120 links, but my CBR uses 114. I practiced breaking chain on my old chain before I did my new one. I asked Speedwerks if the peened head had to be ground down to push the pin out of the chain, but Brian said no. I tried it both ways.
So breaking chain with the Jumbo was easy, even my new chain. After taking off the old sprockets and putting the new ones on, I linked my DID onto the old chain and pulled it around the sprockets. It fit.
Now I had to press on the side plate. Couldn't practice on this since DID only gives you one. I used my old calipers to measure the width across the side plates on the DID chain. I greased up the master link with the x-rings and started pressing on the side plate. Unfortunately, you cant measure accurately with the calipers how much the side plate is being pressed on. I got it as close as possible and took off the Jumbo. It was right on.
Now I had to rivet the master link. The great instructions with the Jumbo said to refer to the chain maker. I threw the DID box away now, but it was very vague about a round flare. So I started making a round flare in the rivet dimple with the Jumbo. So I'm on my hands and knees holding the jumbo on the chain and turning the bolts. I did a couple turns and unscrewed the Jumbo. It actually looked like a flare. I did the other one even better and was able to redo the first one. Tested it today and the chain stayed on.
