Buy the ticket, take the ride.
Hey --- Here' something i ran across on my old saved emails the other day... It was sent to me back when i had a 360 by a gentleman on the SOHC forums... He also provided me with a .pdf file that is an 8 page shop manual supplement detailing the fix for the tensioner unit. Send me a PM with your email address if anyone wants it, and i'll send it on to you...
I love the slotted front sprocket cover on the 360 engine. Looks tough.
Anyways... Here's the email that was sent to me:
"To begin, this modification came out in 1975 and would only apply to models of that model year or earlier. Since the CB360 was produced for two years beyond that, the '76 and '77 models should be fine as is.
I've attached a pdf. copy of the Honda Factory Supplement covering the entire procedure. I've also listed below, the parts that you'll need. The slipper may be bit of a challenge to find. I obtained mine through David Silver Spares in the UK. The other two parts are commonly available through Honda dealers. One cautionary note: Make sure that the parts you locate are, in fact, the updated parts. The last three digits of the part numbers indicate revision code. By way of example, 000 would be the original design and 010 and 020 would be the first and second revisions respectively. Some old-stock Honda dealers may still have the original versions (000), which, of course, would not support the modification.
Tensioner Update Parts List
1 Slipper, Tensioner

1 Upper Tensioner Slipper Holder

1 Damper A, Tensioner
14565-369-010
I'm not sure how many miles you have on your 360, but left unmodified you'll likely start having wear issues by 12,000 miles or so. The problem will manifest itself through extreme wear of the slipper (grooves caused by the cam chain). The next stage will include wear (grooves) in the upper slipper holder, at which point there is metal on metal contact. Rarely will this be evident by listening to a running engine – it must be disassembled and inspected. If the wear on the upper slipper holder is significant, you'll probably need to replace the chain, as well.
Despite its lack of popularity, the 360 is a great little engine and very durable once this modification is performed. One other common problem is bad spark plug boots. Since they're still available from Honda and fairly inexpensive, I make it a habit to change them out on all of my restorations.
