Classic Motorcycle Mechanics

From road to track: a guide!

-

There’s no scrutineer­ing at track days so it’s up to you to make sure everything’s safe and secure on your bike. Here are some to-dos…

1/ THROTTLE

You want a throttle that snaps shut like Bertie’s wallet and it needs to do this on full left and right lock. Any cables that foul or snag need either re-routing or a cable tie or two to keep them in place. A squirt of silicon spray (on the outside) helps a cable glide nicely.

2/ LEVERS

Brake and clutch levers need to be in line with your arms so your fingers create a straight line from your forearm when you rest your pinkies on top of the levers. This is the best way to avoid arm-pump.

3/ BRAKES

It pays to change your fluid regularly – perhaps once a season as it’s hygroscopi­c: it absorbs water over time. Check the forums for what pads work best and do invest in braided lines, but don’t go for the ones that loop over the mudguard: lose that, you lose your brakes.

4/ WHEELS

Wheel alignment is always a good thing. If you’re on the tight spectrum like us the next time you adjust your chain you could use two strip light bulbs (gun-shot straight) and hold them against either side of the rear tyre and measure the distance between them and the front tyre on both sides. Chain adjuster marks are not to be trusted.

5/ ENGINE

Change your oil as often as you can afford it. Some say that 100 track miles is the equivalent to 1000 road miles. Keep air-filters/boxes clear – especially post gravel-trap visit!

6/ TYRES/PRESSURES

Stick to road legal tread depths. For £50 I bought a bead breaker, balancer, rim protectors and levers and now do all my own tyre changing (local shop wanted £25 per wheel) you do get quick at it with practice. Pressures: ask whoever you buy them off. Every manufactur­er is different. Measure and adjust the pressures from cold at the start of the day.

7/ SUSPENSION

Needs to be in good order, be it stock or uprated: if you don’t understand it enlist the help of experts. If you do, keep notes and only make one change at a time.

8/ REAR-SETS/COMFORT

You want a bike that’s comfortabl­e: don’t worry about hi-rise foot-rests just yet. Tank grips make a huge difference in braking zones as it allows you to take some pressure off your old, emaciated arms.

9/ RACE BODYWORK

Cheap and better than crashing in (often rare/pricey) 1990s fairings.

10/ EXHAUST

While everyone loves the sound of the current Motogp bikes and the 1960s Honda sixes, this may not win you friends at certain race tracks. Many have quite stringent decibel/noise levels and your bike must hit these. On this SV we’ve got a standard can, but many aftermarke­t cans come with removable baffles for more/less noise.

Also... TOOLS

Buy a torque wrench to avoid those ‘did I tighten them enough?’ moments.

LOCKWIRE/LOCTITE

You can go mental and lock wire everything but, to be honest, you’re just making stuff difficult for yourself. Same with thread glue. If it rarely gets taken off the bike for routine maintenanc­e, apply a dab of Loctite to the threads. If it’s on and off, just torque it to factory settings. There’s no need to lockwire sump-plugs unless you’re going racing: just refer to that workshop manual and use your torque-wrench. DO lockwire both handlebar grips: avoids that horrible ‘two throttles’ feeling.
