Track Day Planning

I'm pretty keen to go do a track day, and I have a buddy who is the same.  The Grand Bend Motorplex does motorcycle open lapping on its track.   I found GBM through motorcycletrackdays.ca.  The upcoming SOAR racing event at Grand Bend offers open motorcycle lapping prior to their weekend events.  That might be a good time for two nØØbs to go as there will be experienced track day people on hand to help us fumble through the technical inspection.

I figured it would be a show up on what you rode here on and go on the track, as you would with a car, but bikes seem a bit more involved.  Here is the list of motorcycle specific technical requirements:
  • Is your kickstand secured? Your spring return isn’t enough on a racetrack. Use a plastic strap tie or duct tape to secure your kickstand in the up and locked position before you come to tech. 
  • Tape over your speedometer. It’s the rule.
  • Make sure your throttle returns quickly and positively. We want to see it snap back when you release the grip. 
  • Change your antifreeze for straight water. If your bike puts antifreeze on the surface, it shuts the entire track down and may result in suspension. Antifreeze is 100 times worse than water on asphalt (It’s like wet ice). Swap it out for water before you proceed to tech. 
  • Tape over or remove lights, signal and mirrors. They all shatter and they all puncture tires. 
  • Brakes: Make sure they’re properly functioning, front and back, with no leaks, because we’ll check. 
  • Chain: Check your drivechain adjustment. Too tight or too loose means breakage. Refer to manufacturer’s specification. Also, check your master link. A rivet style link is preferred, but a standard ‘slip on’ while suffice if you put a dab of silicone on the key to secure it. 
  • Now that you’ve ensured your brake lines don’t leak, check the rest of the bike. Your engine and suspension components must also be leak free. 
  • Overall track worthiness: These are the small things that can lead to disaster. Loose lines can snag. If it can flop around, it can be snagged and lead to a crash. 
  • Body: All body parts must be secured or removed. 
  • Mechanical: Check your fasteners and ensure they’re secured at recommended torque. 
  • Tires: Properly inflated, with structural integrity intact (sidewall, tread, steel-belts, bulges).
Most of that is common sense/maintenance, but there are a couple of bits that will require some thought.  Tying up the kickstand is all well and good, but that means you're bringing a rear stand to keep the bike upright.  Swapping out the antifreeze also means you need to bring some distilled water.  Some tools, disposable gloves and fluids would probably be a good idea too.  Suddenly the back of the bike I want to ride to the track day is looking like a hardware store.  You wouldn't want to ride an hour and a half to a track to find out you don't have what you need to go around it.  Short of asking for a pit crew to accompany you in a four wheeler, riding solo to a track day seems difficult if not impossible.

Of course, this leads you down the road to a trailer, which then begs the question, why use your road bike for track days when you can pick up an older sport bike for not much, not have to pay for road insurance on it and spec it out specifically for track days.  Stripped of lights and needless accessories like rear foot pegs and indicators, you'd be ready to ride as soon as you roll it off the trailer, and the machine would be tailored for the track.

I've been to several racing schools, but the one time I really got into it was while living in Akita, Japan.  Kyowa Race track was a small carting track deep in the mountains south east of the city.  Kazutoyo, a student of mine, was an avid racer (he came to Canada for a summer to participate in a Mosport racing mechanics program).  We'd go up there half a dozen times in the summer and spend the day hauling the carts around that bendy circuit as quickly as we could.

The vehicle of choice for the carts and the paraphernalia that went with them was a cargo van.  We'd be able to fit three people, the tools, the disassembled cart and spare tires and other odds and ends all in the van and head to the track.  Riding around at break neck speeds was awesome, but I have fond memories of all the fettling that when on in the pits too; it's all part of the race experience.

Ford Canada's handy Transit Van Builder got me all
set with a customized utility van that could carry two
bikes and gear with ease... things I'd do if I were rich!
Now that I'm thinking about doing a track day on two wheels I'm tempted to imitate those Japanese carting guys and get what I need to make a track day possible.  I've been wishing for a trailer several times this summer to haul lumber.  Having one on hand and a vehicle to haul it would be handy for more than just track days.  

Or just win the lottery and get the full on racing support van.

If Mechanical Sympathy were to go full on into racing, I'd grab that 1000cc VFR from Angus (in my Transit race van) and prep it for racing.  Stripping off all the lights and extras and minimizing it down to a race bike.  I'd be a dangerous man if I had more money.

In the meantime I'm still trying to look for ways to ride my Ninja to the track and do some laps without dragging along someone in a cage to support the activity.

KLR Curiosities

A super high mileage KLR, but it's pretty new (mid-00s).  Unclear on its mechanical details, other than it's very tired and the plastics and tank don't match.  

$1300 seems like a lot to pay for a bike in such condition with unoriginal parts (probably because it's been dropped hard).

If I got it I'd shelf it for a year while I broke it to pieces and rebuilt it.  I might go as high as $800, but I'll be spending a lot to give this tired old bike a second life.  I've asked the owner for info...

Followup:  I got a fantastic response from the owner.  The bike has been fettled to within an inch of its life.  The first owner took it from Alaska to Tierra del Fuego, and did the Demptster Highway.  The second and current owner has taken it to James Bay and various off-road adventures in the past couple of years.  It hasn't been dropped recently, but it's an off-road capable bike, so it's been down, once in Chile where they rider had to order in a new instrument cluster, the mileage is uncertain with the replacement instruments.  This bike has had a life, and now it's for sale in Southern Ontario.  

I suggested he sell it back to Kawasaki, this KLR shows what KLRs are capable of.

The mods list is extensive:
EM Doohickey
Upgraded headlight wiring harness with relay
Headlight cut out switch
Glass fuses replaced with blade fuses
Oversized side stand pad
Subframe bolt upgrade
Scott chain oiler
Progressive 420 Series rear shock
Instrument and idiot lights converted to LED
Choke relocation mod
Stainless front brake line
Headlight modulator (not hooked up but still in the fairing)
UNI air filter
LED plate light
Perelli M21 tires with lots of meat on them
Shell Rotella every 2500km or so

Intercepting Possibilities

I just came across some dream project bikes.  There are a pile of '80s Honda Interceptors online this week, and an interesting little VT500.


Low mileage but not in working condition, just what I need to break down and rebuild!












Asking only $400, but it's a hike out the other side of Toronto.











For $700 there is a higher mileage but better cared for Interceptor just up in Angus that comes with all the shop manuals.








Or I can drop $700 on bits and pieces in Kitchener and put an Interceptor back together again, because dude took it apart and now has a garage full of unspecified parts.  Brilliant.  Seven hundred bucks might be a bit much to clean out his garage, though it's close by and it'd be easy to go pick up.  Might be a good choice further down the road, but not for a first project bike.



Another possibility is the Honda VT500.  This air cooled beauty is in great shape and would be a fantastic starting point for a cafe racer build.  It's been well taken care of and I could probably ride it home from out Brockville way.






Lots of possibilities on Kijiji this month...

Project Bikes

I got a couple of nibbles on Kijiji from my 'got an old bike in your shed you want to get rid of?" ad...

1979 Suzuki GS850, not running, asking $500



A review on this specific bike from the UK shows a lot of love for it.

Here is a history of the GS850 series of bikes from Suzuki.  It's a touring bike and weighs in at around 600lbs.  With a shaft drive and that weight it isn't exactly ideal as a cafe racer rebuild.  It is however air cooled and those pipes are lovely. Something other than a cafe racer could be

the goal.  This military style build is interesting.

As a bobber style bike with a saddle, the GS850 has some potential!





 



1986 Honda Shadow 1100cc, no info given, asking $500


Another big cruiser (many people seem to have these old lumps lying around).  Shaft drive, massive motor, covered in things.  Everything I don't like in a motorcycle.


If these get customized, it seems to be along chopper lines.  I think I'm holding out for something a bit less, um, big.

Chain and no Agony

Follow up to Chain & Agony and How to Size and Replace a Motorcycle Chain...


The whole process of breaking the chain and installing it took about half an hour this time around.  The o-ring chain I got was easy to break using the tool I picked up, and installing the new master link on the chain took only moments.  The three in one DRC Chain Tool I got (chain breaker, outer plate presser, rivet presser) was easy to use and looks good doing it.  It might be my favourite tool at the moment.


The chain-breaking tool comes with two sizes of /privet pushing bit.  The blue bit was for 500 sized chains (the Ninja's is
a 520).  You back off the big bolt and install the push pin, then use the smaller outer bolt to push the pin into the rivet on the chain. The tool automatically centres the rivet, so you're true all the way through.
The new chain was a 120 link chain, the Ninja takes 114 links, so that's 6 links off the end.  The hole in the
top is where the chain pin falls out once you've pushed it through.
Close-up of the blue chain bit .  There is a pin inside it that the outer bolt pushes through, pushing the rivet
right out of the chain.  Once the pin falls out the chain falls apart.  You end up with a clean break and two
inner chain links ready to be re-attached on the bike with a master link.
Six links of the 120 link chain removed.  One pin is pushed right out, the other was pushed
out far enough to dismantle the chain.
I installed the master link on the sprocket - it keeps everything lined up and made installation easy.  After
pressing on the side plate (gently, checking that it's in line with the other links and the chain has play in it),
the only tricky bit was installing the retaining clip, it took a few tries.  When you get it though you know for
sure because it makes a very satisfying click.
With the chain back on and lubricated, everything is tight.  The change to how the bike feels is subtle
but very satisfying.  The engine feels much more firmly connected to the back wheel now.  No sags and tight
spots like on the old chain.

I got this mighty DRC Pro chain
tool
at Royal Distributing in
Guelph
.



Now that I've got a handle on this and the right tools for the job, chains don't worry me any more.  This process also emphasized how surgical bike mechanics are.  I started off doing heavy equipment repair as a millwright and then did a couple of years in automotive.  Compared to that kind of work, motorcycle mechanics feel more like surgery than butchery.  Patience and a careful hand are more important than brute force.

Now more than ever I'm looking for an old bike to dismantle and rebuild to get an inside feel for how motorbikes go together.
