How many links on a CB350/CL350 chain
« on: August 10, 2007, 02:26:36 PM »
According to the shop manual, the CB350K4 has a 94 link chain and 36 teeth rear sprocket, while the CL350 has a 96 link and 38 tooth sprocket. That makes sense, as the CL is intended to be an all-terrain bike and the acceleration is favoured instead of top speed.

I ordered the transmission kit for my CB350 twin a while ago. I had to buy the 36T sprocket separately -probably you remember my "chain&sprocket woes" thread-. They sold me a 96 tooth chain, saying that they had it ready for another model, but I could cut the two additional links if I needed to.

The day for chain installation arrived a few days back. When I tested the whole set, the rear axle was going too far back in my opinion. Most of the swingarm hole was seen in the front of the axle. My reasoning was that, when the chain stretches, I would run out of space to tighten it. Surely, it was due to the two additional links. Before cutting the chain, I calculated where the axle would go when I'm done. As two links had to go, it's like removing one in the upper section and one in the lower section, that is, the axle would move one pitch forward. That would place it straight in the middle of the elongated hole.

But when I finished cutting, I had to move the axle up to the very front, and even had to remove the chain tensioner bolt to allow me to connect the two ends with the master clip. Then I would be able to tighten it but the axle would stay in the very first notch.

I don't understand why it moved that far forward, specially when it is the right size according to the manual. I don't really think the chain will stretch that much, and even worst, after fitting the rear fender it seems that the wheel is not "centered" with relation to it, that is, there is far more space in the back than in the front.

What did I do wrong? Isn't 94 teeth the right size? I'm considering buying another chain but it hurts to throw away a brand new Tsubaki Omega chain...

Bump! Nobody have a clue why with the length specified by Honda the chain ended up being too short?

Raul, difficult to tell from your pic but the wheel is rarely "centered" and yes the chain will use all the adjustment that is there as it "stretches"---bit of a misnomer there as chain doesnt stretch the pin bearings wear alowing the length to increase.

When you get some pressure on pins from using it, it will loosen off dramatically as some of the grease gets squished out of bearing surfaces.
