A very expensive traffic jam

I just finished watching the F1 parade in Monte Carlo.  Watching the massive, modern F1 cars (so wide they practically fill the road) following each other through the streets of Monte Carlo reminded me why I’ve been watching MotoGP instead.  It’s not uncommon to see multiple lead changes on a single lap in MotoGP, and dozens of mid-field overtakings during a race.  It’s uncommon to see any lead changes in an F1 race and a driver climbing through the field has become a rarity.  At Monte Carlo this morning the only overtaking was political.

I started watching F1 during Michael Schumacher‘s rookie year and followed him all the way through his career.  My favourite race of his was ’94 in Spain where he managed second place while stuck in one gear.  Spain a couple of years later was a master class in keeping an F1 car on the pavement in torrential rain.  While the engineering is interesting in F1 it’s not why I watched it regularly for over two decades, it was because of the brilliance of the drivers.

I’m now into my second season of watching Motogp.  The first race I watched had a resurgent 34(!) year old Valentino Rossi chasing the astonishing Marc Marquez (beginning a record breaking run of wins) to a one two finish with multiple lead changes in a single lap.

In one of the early races an announcer mentioned how in Formula One the car is the majority of the equation whereas in Motogp the rider is the key component.  From that moment on I made an effort to understand the complexities of riding a race bike.  Motosports that are decided by operator skill over engineering prowess (and budget) are what I’m into.  Schumi got that second place in Spain driving a second tier car.  When he started winning championships with a massive budget I was less interested.

Watching the parade around Monte Carlo reminded me of why I enjoy the bikes more.  With the rider such a big part of the equation, you’ll see human excellence much more clearly on two wheels than you will with four. There is much less between a rider and the road than there is between a driver and the road.  While one is wrestling with their machine the other is setting suspension settings and adjusting engine maps.

With the Isle of Man TT coming up I’ll also be able to see bikes battling on public roads just as the F1 cars didn’t do on the streets of Monte Carlo. You see a lot of precision in Monte Carlo but you don’t see the breath taking bravery that you’ll see in the TT.  If you’ve never watched one before, give it a go.

This has me thinking about vehicle dynamics and the differences between motorcycles and cars… fodder for my next post…

After banging my head against a non-starting PW80 for the better part of two weeks I went back to basic troubleshooting.

The one thing I changed prior to it dying entirely was the spark plug.  The only NGK I could find was a BPR6HS, the bike is supposed to take a BP6HS.  The difference is a resistor which prevents feedback to electronic equipment in the system (important if you’ve got a machine that uses computers and other finicky components – the PW80 is nothing like that complicated).

I’d read that the resistor doesn’t matter, but after swapping back to the old plug the bike fired up immediately.  I’ve got to look further into resistor effects on simple two stroke machines like the PW80, but the troubleshooting still stands: when you change something and it suddenly stops working, change it back even if you think it’s supposed to be an improvement!

I’m going to regap and try the newer plug again, but if it kills it again I’ll have to accept that the PW80 doesn’t like (and doesn’t need) a plug with a resistor in it.

After it was up and running we had a throttle lesson, walking next to the bike while my son got a feel for rolling on the throttle gently.  I then tore around in circles on it – it’s a zippy little machine!

This changes moment to moment, but based on bikes I’ve actually thrown a leg over, and the shear avalanche of reports on the Ninja H2, I’ve got a couple of new machines on my wish list.

Sport Tourer:  Honda VFR800

It’s a jewel like machine with beautiful finish.  It’ll run all day, has a magic variable valve engine, and can corner with the best of them.  It also hits a nostalgic button with me.

$14,500

Bonkers Super Bike:  Kawasaki Ninja H2

A supercharger?  200+ horsepower?  It has wings for godsake!  It’s a technological tour-de-force and one of a kind.  I used to be all wobbly over Hayabusas, but the H2 is a daring step in another direction.  It ain’t cheap, but it’ll be collectable one day.  If I were ever to do Bonneville, this’d be the bike to bring.

$27,500

Off-road ready Dual Sport: CCM 450 Adventure

A light-weight, off-road capable dual sport bike with a bullet-proof BMW engine that can handle everything from actually adventuring off road to long distance travel.  It’s the bike that would get me coast to coast to coast in Canada.

$10,000 ?

Wow, that is a well groomed man.

Back To Basics:  Ducati Scrambler

An air cooled single that does the business and reminds you what motorbiking is all about.  Just you and the wind.  It’s light, engaging and charismatic.  I’m in even if I do have trouble connecting with the demographic they are aiming at.  Under all the marketing the Scrambler is a lovely little machine that does the business.
