Honda PC800 – Right Wrist Twist http://rightwristtwist.com Today's Greatest Motorcycle Blog Thu, 01 Dec 2016 19:00:15 +0000 en-US hourly 1 https://wordpress.org/?v=4.5.2 The Hack Mechanic Fixes A Flat http://rightwristtwist.com/how-to/the-hack-mechanic-fixes-a-flat/ http://rightwristtwist.com/how-to/the-hack-mechanic-fixes-a-flat/#comments Mon, 18 Jul 2016 14:31:01 +0000 http://rightwristtwist.com/?p=452 I have to admit something. Just between you and me, I’m not very good at wrenching on bikes. I’ve never done my own valve adjustments. Carburetors are little boxes of black magic to me. Part of the reason I got my Honda PC800 is because it was designed to be an extremely low maintenance bike, and with only one exception it has been. I can do simple stuff like add lights and change my own oil just fine, but beyond that I tend to call a shop rather than dive into things myself, because in many cases I simply don’t know what I’m doing.

Particularly since I tend to ride older bikes – my PC800 is the newest bike I’ve ever owned, and it’s 18 years old – this can get me, and particularly my wallet, into trouble. I bought my last pair of tires (Metzeler ME880, if you’re curious – one of the few tires that fit my bike) at The Shop That Shall Not Be Named. Let’s call them Voldemort Garage so I don’t get sued (please be kind, J.K. Rowling). A week or two later, my rear tire sprung a slow leak. The valve stem had started to pop out of the rim. I brought it back, and they fixed it – and insisted on charging me for it, even though an improper previous installation caused the problem, since my old tire never leaked. A few weeks after that, I was out cruising western Massachusetts with my now-wife on the back, and THAT valve sprung a leak. I was lucky to save the resulting tankslapper, not dump the bike or my wife, and pull over to the side of the road where we spent the next two hours waiting for a tow. I took it to Central Mass Powersports who replaced the valve stem, and the tire which, in their opinion, had been ruined from many miles of low pressure. My back tire never leaked again.

Flat tire on I-89
Our story begins here…

On my recent SaddleSore 1,000 shakedown, it was my front tire’s turn to go flat. After my darling, wonderful wife, who I’m still very much sucking up to, hooked up the trailer and drove 60 miles to come rescue me, I tracked down the cause to – surprise, surprise – the valve stem, which had been installed by Voldemort Garage. As a great philosopher once said, “How hard could it be?” I’m a hack mechanic, but even I, under the watchful eye of my professional auto tech friend, managed to use his shop’s equipment to swap tires and install four valve stems, none of which ever leaked.

I don’t have a tire machine at home. But RWT‘s Kate Murphy owns half of one, and offered to help me swap tires myself rather than have a shop do it. She pointed out that you can buy tires online for much less than shop prices, plus you don’t have to pay the mounting and balancing fee. As it turns out my tire is actually fine. The air leak is much faster than last time, which means I didn’t ride on it after it started leaking and cause excessive wear to the tire. But I still needed to replace the leaky valve stem. No worries, said Kate. They have a zillion spare valve stems, and we didn’t even need to fully remove the tire to replace it. Great, so I’ll just load the bike on the trailer and take the wife’s car over to deal with it…

…except my wife can’t drive my car. It’s not she can’t drive a stick, but that the motion of shifting my Subaru BRZ causes her pain. Being stranded at home with her kids and no wheels is bad. How was I going to get the bike there? Just remove the front wheel and bring it alone, said Kate.

I autocrossed seriously for several years. I used to swap all four of my street wheels for wheels with sticky R-compound tires, race all day, then swap back to my street wheels and drive home. I’m not NASCAR fast, but I can swap all four wheels myself in about 10 minutes given the proper tools. But I had never removed a motorcycle wheel myself before. I can’t even get my PC800 up on its center stand by myself. But wait, I no longer live alone. I just need someone to give the bike an extra push from the front, and it’s there. So I did. But the bike sits on the stand and the front wheel, not the rear. Throw some weight on the back, suggested Kate. So I put the old warped brake rotors from my wife’s Ford Flex in the trunk. They’re heavy, but not heavy enough. After looking around the garage, I grabbed one of my snow wheels/tires from my BRZ, placed it on the back seat, and BAM, the bike rotated on its center stand onto the back wheel, lifting the front a few inches off the ground. With a bungee cord to hold the wheel to my top trunk, I was ready to pull the wheel.

First I had to pull the calipers. Having done many brake jobs on cars, this part was familiar to me. I needed a cheater pipe on the bolts and was afraid of breaking my Allen wrench, but with the extra help they popped and came off with no problem. A single Phillips head screw held the speedometer cable on – easy enough. I had to figure out exactly what direction to tap the axle out with a hammer, but I did, and with just a little jiggling the wheel dropped out. (Thank goodness I don’t have an earlier PC800, with almost a full fairing around the wheel.)

I packed all the bolts and little pieces that came out of the axle into a small box to save for later, and then I was ready to take the front wheel away. It even fits in my BRZ’s trunk without folding down the back seat.

Wheel in trunk
A Subaru BRZ trunk may be small, but unlike a Miata it’ll fit a motorcycle wheel.

After work I drove to Will’s place, the other half-owner of Kate’s half-owned tire machine. We fired up the air compressor, pulled the valve out of the stem, and then Kate broke the bead on one side of the tire right next to the stem. This, it turned out, was all we needed to do to gain access to the stem. The rest of the tire machine served as a table but little more for the rest of the project, since we had no need to dismount the tire any further than that. From there it was a simple matter to remove the old stem (which Kate confirmed was shot), then pull the new one through the hole in the rim.

Valve stem replacement
Dirt on her hands, AND nail polish!

Rather than a stem with a 90 degree bend, we used a short, straight one. That’s what CMP did on my rear wheel, and it’s worked fine ever since, so we decided to keep it simple. And simple it was – pull the valve through the rim until it locked into place. Insert the valve. Add air to pop the bead back on and inflate to 33psi, the PC800’s recommended pressure. Done! I couldn’t believe how quick and easy it was. I spent more time geeking out with Will about Miatas than Kate and I spent fixing my flat. All I had to do now was go home and let it sit overnight to see if it lost any pressure. It didn’t!

“Installation is the opposite of removal.” This sentence is every repair manual’s cop-out for not documenting the reassembly of something it just told you how to disassemble. As a professional technical writer, this irks me. In the case of reinstalling the front wheel on my bike, it was almost correct. Almost. After reinstalling the bearing caps and tapping the axle back through the forks and wheel with a hammer (Jeremy Clarkson’s favorite tool), I discovered that the holes on the non-bolt end of the axle are there so that you can stick something through them to keep the axle from rotating as you tighten the bolt. Lacking a special tool for this, I used a punch and a cheater pipe, then torqued the axle bolt down to Really Friggin Tight (that’s a technical term). The brake caliper pistons needed to be squeezed in a little bit to go around the rotors, but that’s no big deal – I’ve done it a billion times before on my cars. The speedometer gear wasn’t lined up quite right to reattach the cable, so I had to loosen the axle, rotate it, and retighten it. No big deal. All of the parts I removed went back on the bike, with nothing left over. I rolled the bike off the center stand with an inflated front tire.

Kate didn’t trust the pressure gauge on the tire machine, so I finished inflating the tire to the recommended 33psi. (It was 25psi before.) I geared up and took a quick trip around the block. Something in the front didn’t feel quite right, so I pulled over to check all the bolts. That was when I realized that I’d forgotten to tighten the bolts at the bottom of the forks that further clamp the axle in. Oops. I gently rode home, did that, and tried again. It felt pretty good, and I got more and more confident in my repair with each mile I rode. I think I’m back in business – and, thanks to Kate, without spending a dime.

Diving into new territory for my wrenching skills and emerging unscathed has given me more confidence to do more work on my own bikes in the future. This is a very good thing considering the new project I’ve just taken on…

When Car Designers Build A Motorcycle – Honda PC800 http://rightwristtwist.com/reviews/motorcycles/when-car-designers-build-a-motorcycle-honda-pc800/ http://rightwristtwist.com/reviews/motorcycles/when-car-designers-build-a-motorcycle-honda-pc800/#comments Sun, 29 May 2016 22:41:59 +0000 http://rightwristtwist.com/?p=39 Many auto manufacturers build more than just cars. Subaru builds small engines for leaf blowers. Mitsubishi builds practically everything under the sun. And BMW, Suzuki, and Honda also build motorcycles. What makes a great car doesn’t usually apply to a bike, so engineers tend to focus on their specific disciplines. But what if they didn’t?

In 1989, Honda introduced the Pacific Coast 800 – a motorcycle for people who don’t ride motorcycles. It’s said that while Honda’s motorcycle engineers laid the groundwork, they gave their automotive engineers the task of putting it all in a friendly package that would appeal to the average Civic or Accord driver, rather than someone cruising along on a VT1100C Shadow or dragging a knee on a CBR1000F. This commercial from 1988 shows that the PC800 wasn’t exactly aimed toward Harley riders.

Though over 7,000 sold in 1989, sales plummeted quickly, leading to the model disappearing from American shores after just two years. That happens when you market a motorcycle to people who don’t ride. The PC800 returned for 1994, but sold even more slowly than before, with less than 500 sold in its final year. I own a 1998 model, one of the last ones ever made.

IMG_3733_rfdThese days it’s quite common to see crotch rockets or sport touring bikes completely covered in plastic, hiding the innards to achieve better aerodynamics. But in 1989, such use of plastic on a motorcycle was quite rare. American style cruisers and the ubiquitous UJMs hung their inner workings out in the open for all to see. The type of driver-turned-rider that Honda was targeting with the PC800 couldn’t care less about shiny chrome valve covers, so they covered it all up. It looked downright futuristic by contemporary standards, which lead to the PC800 appearing briefly in Back to the Future 2 as literally a bike from the future.

PC800 gauge clusterThe seat is only 30″ tall, making the PC800 accessible to a wide variety of shapes and sizes of riders. The plastic covering continues here, too, as even the handlebars are covered in it. The gauge cluster looks like it came straight out of a 1989 Civic. The speedometer and tach have swapped sides, the fuel and temperature gauges have rotated a bit, and the car-specific warning lights have been replaced with neutral and kickstand indicators, but any EF Civic driver will feel right at home here.

PC800 rearStep around to the back, and the wide wraparound tail light strip bears a striking resemblance to that of the 1989 Accord. Though three bulbs illuminate the whole thing, only the outer two serve as brake lights – again, like a car.

PC800 trunk release leverBut the coup de grâce is the trunk. The PC800 has an unusually wide butt. When you unlock the gas cap on the “fuel tank” (which is fake – the actual tank is below the seat to keep the weight down low) and pull on a trunk release lever (which, again, looks like it was recycled from a Civic or Accord)…

PC800 trunk…the entire top rear of the bike, including the passenger seat, hinges forward just like a car’s trunk lid, revealing two large storage compartments on either side of the rear wheel. These replace traditional saddlebags, and can carry a great deal of cargo. They’re also waterproof thanks to a large overhang from the trunk lid. A previous owner added a Givi top trunk to my bike’s already generous cargo capacity, allowing me to carry everything I needed for a week long tour of New Brunswick and Nova Scotia to ride the Cabot Trail a few years ago. Time, rather than space, prevented me from touring even farther than that.

IMG_3727_rfdSo what’s it like to ride? The PC800 is a unique design that falls most closely into the sport touring segment. But its 800cc motor, sourced from the Shadow VT800, is significantly smaller than the Honda ST1300, BMW R1200RT, and Yamaha FJR1300 that are so popular in this segment. I’m not a particularly fast rider, and while I’ll sometimes use all the power the PC800 can give me up a steep hill or when merging onto a busy highway, I don’t find it lacking at all either. It’s about as smooth as a Harley is not, which is pretty amazing considering that both motors are V-twins. It’s also rather quiet. When you’re in the saddle the bike sounds more like George Jetson’s flying car than a V-twin. Handling is rather good, since most of its roughly 600lbs sits down low in the frame, partly thanks to that low riding gas tank. It’s no sport bike but it’s fairly responsive through the corners. When it’s time to stop, dual discs in front and a drum in back do the job well.

Something you won’t have to do much with the PC800 is maintenance. Many riders enjoy tinkering with their bikes, adjusting and improving them to their own particular specifications. Given the PC800’s intended audience of non-bikers, it has hydraulic valve adjusters, automatic cam chain tensioners, a hydraulic clutch that never needs adjusting, and an electronic ignition. Some of these features aren’t even standard equipment in 2016, never mind in 1989 when the bike was introduced. Shaft drive avoids the tedium of adjusting a chain or belt. And although it relies on a pair of carburetors rather than modern fuel injection, I’ve never had any problem starting it no matter what the temperature.

Mazda CX-5

If I had to compare the PC800 to a modern car, I’d say it’s probably much like a Mazda CX-5. It’s practical, comfortable, easy to ride, and has a good deal of storage space. But when you push it a little, it’s also surprisingly fun – something you don’t necessarily expect given its roots. Perhaps Honda’s motorcycle engineers got the last laugh. Though marketed toward non-riders, the PC800 is packed with enough fun that it might have converted some casual commuters into serious bikers.
