  1. Engine Discussion
    So I was able to score this bike for free and it runs really well. It has been my commuter for a few weeks now. Well today I was riding to work and went change gears and the shift lever was GONE. I was able to pull off the to the side of the road and search for it. Long story short I found the...

    I would like to upgrade to a stainless line, but the only ones I can find online range from 18"-34". I measured mine at 48". Is that right? I cannot find one that long to save my life. I'm new to this, so I'm learning more and more each day.

    I know this is a bit of a longshot, but I'm giving it a go. I've got a 1981 CM400 Custom, midnight blue with lighter blue inset color. When I bought it the left side cover was just the darker blue/no decal. I'm putting it out there that I'm looking for a left side cover *with* the decal. I know...

  9. Tires, Wheels, and Brakes
    I recently (last month) replaced my front brake rotor and upgraded my brake line to braided steel. I had rebuilt the caliper and replaced both pistons in March or April of this year. Everything seemed great, brakes were preforming better, definitely less "spongy." On my last ride, I noticed...

    Hi everyone, I'm having some disturbing sounds coming out of my bike and it seems to be getting worse. There is a high speed/high frequency clacking and almost sometimes grindy metallic sound coming from my '81 CM400C that I recently got (this is my first Honda). It was fine for the first...

    I am a new member from Sumter, SC. I joined about a week ago and picked up my bike this weekend. It's a 1981 Honda CM400 Custom with a little over 6700 miles. PIcked it up yeterday, but it was raining so I didn't get to ride much, just around the block a time or two. Just got back from DMV and...
