When I picked out the model I had some firm objectives:
1. Good two up seating. The wife loves to go.
2. Good cargo capacity for extended trips. Enough for long weekends.
3. Windshield and fairing for weather protection.
4. Reasonable power. As an experienced rider, I wanted some spirit on the back roads and easy highway passing.
5. Less weight and better handling than a Gold Wing. I found the Wing was a pig around town and back road driving was boring.
There were other contenders: The Kawasaki Concours and the Honda ST1100. But the Pacific Coast had the TRUNK. Once you have seen it, and had it, you can't go back.
I have fixed some things that have improved the bike immeasurably and I invite all Pacific Coast owners to consider these improvements:
1. The stock engine power is OK, but power starts falling off at about 5,500 RPM. I modified the air intake, carburetor jetting and exhaust muffler with outstanding results. The bike now pulls hard to redline in all gears and can keep pace with sportbikes in the same size engine class. The difference is truly amazing. For detailed information, review my posts and drawings at http://pc800.co.uk/cgi-bin/mwf/forum_show.pl
2. I spent considerable time researching better tires for the bike. I finally settled on Michelin tires. The front tire is a Road II 120/70 and the rear is a Commander 140/90. The difference has to be tried to be appreciated. The steering is crisp and confidence inspiring. Handling is like a sport bike and the braking is awesome. The ride is smoother. The tires are wearing extremely well. I'll get at least 3 seasons out of them. Maybe more...
3. Purchase a set of Hagon rear shocks. They are adjustable and have good damping. I recommend the middle setting.
4. I found the bike prone to some headshake at about 160 km/hr. I made two spacers 32mm in diameter and 19mm thick and placed them on top of the fork springs to increase the fork rake. Combined with new fork oil (10wBelRay) the front end was completely stable at all speeds and the smooth ride was even better.
5. I bought and installed a new headlight bulb with better specifications. White color, low beam at 55W, but the high beam is 100W. MUCH better. Also, I installed high wattage bulbs in the fairing signal sockets and they show up better in the daytime.
6. Seating. After a short time the seat is uncomfortable. For driver and passenger. The economical fix is to buy an automotive seat pad with a gel core and insert a thin (10mm thick) foam pad on top. Now you are good for hours. I also made a custom back rest for the passenger that is 100mm higher and 20mm thicker than stock and the wife loves it. She says it's like riding on the Wing.
7. Buy or make a pair of handlebar risers that raise the bars 19mm. When you tighten down the bars, pull the grips towards you a bit so that you don't have to reach so far. Greatly decreases back fatigue. If you do this, you will have to add a short extension on the head of the ignition keys so that they will reach into the molded plastic aperture.
That's some of the improvements I have made so far and I'm pleased with the results. With a few changes that don't cost a lot, you can make your good Pacific Coast into a great ride. I love the bike. I'm happy enough that I'm really not interested in a different bike, even though the new models look appealing. However, if I win the lottery, a new BMW 4 cylinder may sit beside the Coaster. Or a Yamaha V-Max. Sigh.. So many bikes and so little cash.

I am thinking about purchasing a 1989 PC800. I enjoyed reading about your modifications. I went to the link that you included in your review, but it didn’t illustrate how your modifications were done. If I purchase this bike, I would definitely want to do these modifications. Would you be willing to send me some information on how to do these modifications? Thanks.
