MP Proj. 001 Honda CL 360 Part 11: Valve Cleaning

Exhaust-Side Valve on the Honda CL 360

Finally got around to cleaning the valves on the Honda CL 360.  While I hoped it would go just like the piston heads, the carbon build-up on these valves was thick, and the valves themselves are awkward to clean.  I soaked them in Mineral Spirits, hoping to loosen the carbon, but that didn’t seem to do much.  So I went at them with a brass wire brush, and some Simple Green.  That helped a bit, but it took a lot more elbow grease than cleaning product, to finally get the build-up off the damn things.

MP Proj. 001 Honda CL360 Part 8: Piston Cleaning

Pistons Before & After

With the appointment to meet my friend, to help me hone the cylinders today, I figured I would take a little time to clean the pistons up. I had made a snap decision, which turned out to be a bad one, purchasing a set of used pistons and rings from eBay.  Everyone then told me that it was definitely better going with a new set of rings, and that the pistons I already have should be fine.  Lesson learned.  I will turn around and try to flip the pistons back on eBay.

MP Proj. 001 Honda CL360 Part 7: valve leak test

Head: Pre-leak test

Although the last few posts about this build have probably been less than riveting, I have wanted to make sure I document the process as thoroughly as possible.  The mundane is often as important as the big moves that will be made, and this test is no exception.  I knew from the start that I would need new rings, after doing the compression test, and then confirmed it when I took the pistons out, and found that the oil rings were both cracked in half.

MP Proj. 001 Honda CL360 Part 4: Tearing the Engine Down


I have been slowly, and CAREFULLY having a go at the engine, to get it ready for honing and the new rings.  The first step was to remove the engine from the frame, and I quickly realized that the design of the frame itself, is so much better for engine repair, than the CB350.  One of the members at Moto Preserve has a CB350, and I have helped him remove the engine several times.  The shape and layout of the frame is such that it makes it rather difficult to manipulate the engine, and finally ease it out.

Cafe racer TV…New Season

Whether you like them or not, it seems that cafe style builds are here to stay for a bit.  Starting its second season, the Cafe Racer TV program will begin tomorrow, August 3rd.  This show airs every Wednesday on HD Theater, so check your local listings.  They highlight some pretty cool builders, and then you watch as some pro racers actually test out the builds, once they are completed.  The show also does a decent job of showing the history of this form of bike, as well as the people and places that have made it a growing, popular form of customization.
