Spring checklist

It’s spring! The snowbanks are slowly receding, and a fresh crop of potholes has appeared in their place. Pretty soon, it’s going to be time to go for a ride, if you haven’t been out already.

But wait! Before you head out, you should give your motorcycle a spring check-up (or, if you don’t know what you’re doing, get a qualified mechanic to do a check-up). It’s probably been a few months since your bike has been on the road. You should make sure everything’s in order before you head back out on the street — your life might depend on it.


First things first

You’re going nowhere fast if your bike won’t start! Before even hitting the starter button, if you stuffed rags into the airbox, exhaust, etc. to keep out mice, rats and other critters, remove them. Don’t laugh — this is more of a problem than you’d realize. When he wheeled his DR350 out of the shed for some mid-winter maintenance, Zac found a family of mice had tried to take up residence in the airbox.

Check to see if the bike fires up. If it doesn’t do so right away, make sure you’ve got the easy bases covered. Start with the no-brainer stuff:

  • Is the fuel petcock turned on (if there’s one fitted)? No? Turn it on.
  • Is the kill switch or ignition in the off position? Yes? Turn it on.
  • Are there burned-out fuses? Yes? Replace them.
  • Does your bike have a kickstand safety switch, or a safety sensor that only lets the machine start in neutral?

Drain the carb!

If this doesn’t help, then you may have to do a bit of work — you did remember to take the battery out last fall, right, and drain the carburetors (assuming you have carbs)?

No? Oh dear …

If you have carburetors and didn’t drain them, then do it now (there’ll be a small screw at the bottom of each carb). The small amount of gas in each float bowl loses its combustability over time and cranking the engine only serves to coat the spark plugs in degraded gasoline and the thing will never start (you’ll need to remove and clean the plugs in this case). Letting the float bowls fill up with better gas from the tank will most likely prevent this.

Does your battery need a charge? The starter motor should have a healthy fast spin — no spin and a distinctive clicking sound signifies it’s almost flat. Charge her up, but don’t use a standard automotive quick charger. A quick charger pumps in too much juice for your small bike battery and is a great way to shorten battery life. Use a trickle charger or a smart charger that powers it up slowly (a Battery Tender or similar unit is a good bet here, or your local dealership might be able to help).

If you’ve drained your carbs and got your battery re-installed and the bike still won’t start, it might be time for a more expert opinion, though at this time of year your local dealer is likely rather busy.

Next things next

So your bike fired up and is running okay. Congratulations! There are other things to check over before you hit the street, though.

Make sure you’ve got plenty of tread left on your tires, and check air pressure as well. Make sure there’s no other damage (partial punctures, etc.).

1) Tires: Did you wear your tires down to the cords before parking the machine last fall? You should replace those worn-out sneakers before venturing out on the streets.

And even if you’ve got plenty of life left on your tires, make sure you check air pressure — even sitting, a tire will slowly leak air.

Now would also be a good time to check your tires for flat spots or any other damage that might not have caused a flat last year, but is trouble waiting to happen. Look over your rims and check your spokes (if applicable) too.

2) Driveline: Check your chain (if you have a chain) while you’re messing around with that rear wheel, and eye up your sprockets. Are they worn? Replace ’em if the teeth are getting hooked or the chain adjusters are maxed out. If they’re good to go, make sure your chain slack is set properly, and give it a good lubing.

Even a shaft drive needs maintenance, although it’s much less regular than a chain. Spring is a good time to check it.

If your chain constantly needs adjusting, or it has a lot of kinks, it needs to be replaced. If the teeth on the sprockets are getting hooked or obviously worn-down, then they’re worn out. Most riders replace both at the same time. If you’ve got a belt drive, make sure the belt is in good shape — no broken teeth, frayed edges, or squeaks. They don’t usually need much adjustment, but everything wears out eventually, so take a look.

Shaft drives are extremely low maintenance, but still require periodic tinkering. If you don’t change your gear oil, you’re running the risk of catastrophic failure. Make sure your shaft drive maintenance is on schedule. If you don’t have a manual that details the procedure for your bike, try a Google search.

Check your bike’s bearings every spring. If your wheel bearings get as bad as the one on the right, you could be in big trouble when it fails at speed.

3) Bearings: Ensure your front and rear wheels spin smoothly with no sideways play; if you feel a grumbly bearing, replace it (or it will fail at a much more inconvenient time).

Lift up the front wheel and move your handlebars from side to side as well, making sure they move freely without any notchiness (especially in the centre). Also, grab the wheels and move them side to side to check for any clicking in the swingarm bearings.

4) Brakes: Make sure your brakes are still in good working condition — check the pad thickness, and make sure brake lines aren’t cracked or degraded. If your disc brakes are mushy, it’s time to change the fluid (you should do this every few years anyway, so if you can’t remember the last time you did this, now’s the time). If you’ve got drum brakes, make sure the shoes are within spec, and make sure the cables/rods are in good shape (put some lube on that adjuster so you can move it when needed). And make sure the brake lights work. Speaking of which …

Are high and low beams working? Don’t forget to check your signals and brake lights, too.

5) Lights: Make sure the horn, high beams, low beams, signals, brakes and any other lighting works. Remember last year, when you made a mental note to pick up a couple of spare fuses for your onboard toolkit? If you’re anything like us, you promptly forgot. So now’s a good time to add a couple of spare fuses. If you’re really serious, you could even add a spare bulb or two.

6) Controls: Is your throttle sticky, or moving freely? If it’s gummed up, make sure it’s working properly before you ride. Make sure your clutch lever moves freely as well, and check over your electrical switches.

7) Air filter: Make sure no mice chewed holes in it, if you forgot to block off the airbox. Clean it if it’s in good condition, or replace it if it’s looking ragged or blocked.

8) Coolant: Got a liquid-cooled bike? Make sure your coolant is topped up according to manufacturer specs. If you haven’t changed it for a while, now may be a good time to do so.

9) Valves: If you’re due for a valve adjustment, now is the perfect time. Either do it yourself, or take it to a shop. If you’re doing this, do it before changing the oil as the motor needs to be cold for this one.

10) Oil: Unless you changed your oil before putting the bike away last fall, you should do an oil change now (run the motor for a few minutes first to thin the oil). That old stuff likely isn’t in the best shape at this point. Oh, and you might as well change the filter while you’re at it.

Be aware that some bikes, like Harley-Davidsons, have separate oil for the gearbox and crankcase, thanks to their dry sump design. If this is the case, make sure you’ve got everything topped up appropriately, but make sure you don’t have oil in the sump before you add any more, otherwise you’ll have oil spraying everywhere when you fire it up.

11) General maintenance: Make sure all the main bolts are still bolted on tight. Engine, suspension, luggage racks, windscreens, skid plates, and any other added bits. You should check the torque on your axle nuts too. Make sure there’s no loose bodywork.

Make sure you have your insurance and registration up to date and on your person.

Hit the road (not literally)

Yeah, yeah, we know you’re excited. But, don’t do anything stupid while your skills are still rusty.

Congratulations, you’ve spent enough time looking over your bike that, if something was wrong, you should have spotted it. At this point, it’s time to go for a ride — just be careful out there, because a long winter without riding will be sure to leave you a tad rusty too!

  1. When the bike sits for a long time and never gets warm, humidity can seep into gaskets and seals, corrosion can form on surfaces, rubber seals can dry out if they were old when you put it away.

    Before you start it up the first time. Make sure it’s over clean ground or at least take a look on the ground and not if there are any stains. Start the bike, let it run for a few minutes without moving it, and then turn it off. Do not move the bike. Wait 15 to 30 minutes, then go back to the bike and inspect the ground again.

    Anything leaking out of the bike and to the ground? Any new oil or coolant leaks?

  2. One trick my father (who was a mechanic) taught me was to open the carb drain taps and let some fresh gas run through; it will wash out some micro-sediment, dilute and refresh any remaining gas (draining doesn’t always clear them completely) and I find it really helps ensure a quick start-up in spring.
