Motorcycle – Page 19 – Not Your Average Engineer

A fellow PCer on the PC800 Facebook group dissected the exhaust system from a Honda Pacific Coast and was kind enough to share the photos with me. ~~Unfortunately I don’t remember who gave me the photos. If it was you, please let me know and I will give you credit!~~ Thanks to Jesper Milling for these photos! And thanks to Dolf for figuring out who they came from originally!

This is the muffler. One of the baffles in here causes the tweeting noise that 1989 PC800s are especially plagued with. A weld can crack and fail which makes it tweet or whistle under the right conditions.

Here’s the resonator cavity and how it attaches to the pipes coming from the engine and the muffler.

Another view of the resonator cut open.

The pipes are specific lengths to balance the engine’s twin cylinders.

A view of the dissection with the top half put back on.

One last view of the cutaway in the muffler. This is what makes our bikes wonderfully quiet.

A recent post on the Honda Pacific Coast PC800 Facebook group highlighted some of the awesome modifications people have done to their PCs over the years. I figured I’d round up the photos and post them here. If you have any photos you’d like me to feature of your PC800 or others that you’ve seen, please email me and I’ll add them to this post.

I have to start things out with the Cack, perhaps the most famous of all PC800 motorcycles.

The Cack changed quite a bit over the years with “Vermin” (Phillip Henderson) riding the bike all across North America. You might notice the custom exhaust setup made to cook canned food while he rides and the shopping cart or milk crate pieces on the back. Cack sure got a lot of customization. But now the bike sleeps indefinitely at the Barber Motorsports Museum.

I don’t have many details on most of the rest of these PC800s. These are photos that came from the Facebook group. Notice this one has a different muffler.

This is a pretty neat paint scheme for a PC800.

I think this one is Canadian.

Pretty wild design! It reminds me of the mid 1980s Goldwings.

This bike might be in France.

Wow what a paint scheme! This one is from Russia.

That’s a lot of fancy air brush work.

A yellow bike with a purple haired rider.

Same bike, different rider.

This Honda Pacific Coast looks to be in Ukraine maybe. I like the name on the back.

This is the only purple bike I’ve ever seen.

Neat snow cammo scheme.

This is a wild paint design.

Another cool European PC800. This one might have a spare gas tank mounted above the air box where the faux gas tank normally is. One or two bikes were custom modified by their owners to have that second gas tank.

Another view of the PC800 with the modified top box.

This bike also has a modified windshield that might have come from a BMW or an ST-1100 or ST-1300.

I think this one is somewhere in Europe. Or maybe in Asia. There are quite a few PCs popping up in Thailand and elsewhere these days.

I like the little scooter panniers that were added to the passenger seat.

This is a neat concept bike. I wonder where this bike is at.

This one had a top box put on the passenger seat.

I dig the paint scheme on this bike. And the exhaust has been modified. I wonder if this PC800 actually has dual exhausts.

This bike is really, really pretty!

A nice deep blue PC800 with a custom saddle and a “Wong Wing” on the trunk. It looks like this bike might also have the lower spoiler. Both are quite rare.
