cb750 K1 chain guard alternative
« on: February 20, 2013, 06:27:41 PM »
Hey guys, you have been most helpful to me here, I have a question regarding a cb 750K1 chain guard. mine came with a terrible rigged mini chrome chain guard. I'm going back to stock. I know I need to get the plastic one. the only vendor I am finding is yamiya....and thats $200. I would rather NOT shell out that much for a freaking piece of plastic but will if there are no other options. are there any "close to stock" alternatives whether its a metal aftermarket one that fits the K1? anybody randomly have one in decent shape that wants to save me some money? thoughts, ideas? thanks in advance

I'm pretty sure I have a k1 not being used. If you want I will let you know tomorrow in Am.

Or get yourself a metal one from a K2 onwards, along with a K2 swingarm if you don't want to modify the fitting lugs.

Tews that would be great if you had one.
It may be cheaper to get another swingarm and chain guard but I just got through rebuilding mine and it was a royal pain, I don't want it to befor

The later guards won' fit.  You can probably find a used one for cheaper than the new Yamiya one but it will have faded and may have some small cracks.  I sold one on ebay about a year ago and it was a real nice one.  It went for just under $100.  In case you're interested in the stock look the 69 guard will fit but it is shorter than the 70/71 guard.  The 72 and beyond have the mounts spaced too far apart.

The earlier guard was atop a 45 t sprocket. The longer ones keep the spray from a 48T rear sprocket. Short one on a 48T sprckt may not work well.

Chef, I have an old aftermarket chain guard that correctly fits the K2 to K6 750 swingarm that I’m never going to use. The chrome is shot, otherwise it’s a solid part. Perhaps you can modify and make use of it? PM if interested.
