Springtime Check-up


Did you find time for your bike last autumn? Time to remove the battery, top up the tank to the brim and empty the carburettors before tucking her down for her winter sleep? Well in that case, it won't take much to get your "baby" back up and running and looking good.

Charger resuscitation

So now's the time to fetch the battery that you (hopefully) placed in winter storage and disconnect it from the charger. Once you've re-installed the battery, connect the positive cable first and then the negative cable. Then lubricate the terminals with a little Procycle battery terminal grease. Make sure that there are no kinks in the vent hose (this does not apply if you have a maintenance-free battery). However, if you forgot about the battery last autumn and left it in your vehicle, then you will need to remove it now (disconnect the negative cable first) for a bit of charger resuscitation. If you have a standard acid battery, check the fluid level and top it up with deionised water – obviously not necessary if you have a maintenance-free battery. Unfortunately, if the battery has become deeply discharged over the winter months and the cells are more or less sulphated so that the battery won't charge properly, I'm afraid it's time for a new battery ...

If you lubricated the exhaust and the engine block with fine oil, wipe this off thoroughly and remove any oily cloths from the silencers.

Now you need to check your bike for roadworthiness as well as all the major wearing parts:

  • Horn and lights must be working (low-beam, high-beam, brake light, tail light, license plate light, indicator lights).
  • Check your tyres for signs of ageing, and look for uneven or angular wear. Check the tread depth with a depth gauge. The minimum legal tread depth is 1.6 mm. However, if you want to stay safe in wet road conditions, we reckon that you should start saving for some new tyres once the gauge hits the 2 mm mark. The same applies if the tyres are old and brittle. You can tell how old your tyres are from the production date on the side of the tyre. For example: 4908 means that the tyre was made in the 49th calendar week of 2008.
  • Make sure you change the brake fluid every two years as, even in a closed system, the fluid will absorb water over time, which impairs the performance of the brakes. The start of the season is also a good time to check that the brake pads still have plenty of wear left in them. For more information on how to do this, check out our DIY tips about brakes.
  • Occasional bikers should also change the fork oil once a year (see DIY tip "Fork seals") – and what better time than the start of the biking season! Otherwise, check the oil change interval specified by the vehicle manufacturer (see DIY tip "Fork seals").
  • Replace spark plugs after approx. 10,000 km and paper air filters after approx. 12,000 - 18,000 km (see the vehicle manufacturer's service). Spark plug connectors can also wear out and cause malfunctions – preventative replacement can safeguard against breakdowns.
  • The winter months can also be the time rust sets in, so now is the time to check your bike thoroughly and tackle any corrosion. If you forgot to do it prior to "winterising" your bike, now thoroughly lubricate the drive chain, levers and joints. Get rid of any pockets of rust using sandpaper or a wire brush, then prime with a coat of rust protection paint and finish with touch-up or spray paint Remove any rust on chrome parts using chrome polish, and Alu-Magic polish is great for treating any signs of corrosion on unpainted aluminium.
  • If you didn't change the oil and oil filter in autumn, then you really shouldn't be putting this off any longer (see DIY tip "Oil Change").

And before you take your bike out on the road for the first time, remember to check the tyre pressure and make sure it complies with your owner's manual. If you disconnected the fuel hose from the carburettor, now is the time to reconnect it. If you didn't empty the float chambers before winter, there's a strong risk of varying degrees of resin build-up in the carburettor jets. This can be dealt with by adding some carburettor cleaner to the fuel. A good product for this purpose is Procycle Fuel System Cleaner. In stubborn cases, i.e. if the bike continues to start badly or persistently fails to run smoothly, you will unfortunately have no choice but to dismantle the carburettor and clean it thoroughly (see DIY tip "Carburettor").
