Tyre Pressure
Unless you have a rim lock fitted to your rear wheel, do not allow the tyre pressure to drop below 20 PSI. This is of particular importance on
bikes with 140+ cc engines they have the power to spin the wheel inside the tyre & rip the valve off your inner tube. If you want to run low tyre
pressure for traction, get a rim lock fitted. Lock it, load it & then let your air out. Unless you want to pinch your front tyre on a rock & get a
puncture, the same pressure applies, min 20 PSI. check your tyre pressure before riding else you may be coming home early.
Brake Pads
Check them for wear. Sand destroys brake pads VERY quickly & guess what? most places you will be riding will be sandy. This is even more
so when riding in wet conditions. The sand or grit gets on your disks and eats away at your brake pads. Check them before you ride your bike.
You should have minimum 3 mm pad left before you ride otherwise you could find yourself with NO brakes. Below 3 mm? get some new pads
in there
Spokes
Depending on your riding style, ability & the power of you engine, you are at some point going to need to tighten your spokes. Before each ride,
check all of your spokes especially in the back wheel to see if any have stretched or snapped. Stomp wheels rarely need the spokes tightening,
but please check them before each ride. If you wheel collapses because of loose or damaged spokes it’s likely to cause a bad crash
Nut & bolt check
Regularly go over your bike & check nuts & bolts. If you have stripped components for service or replacement always use Lock Tight thread
locking compound when you re-assemble. This applies to all nuts & bolts on a pit bike.
Replacement Parts
When you need to replace parts always use genuine stomp parts available from your local stomp dealer or direct from Stomp via mail order. Be
aware that although a part may look like a stomp part it is HIGHLY unlikely to be of the same quality. Places like ebay are littered with copy
substandard pit bike parts, only buy the best, and only buy Stomp original equipment & performance upgrades.

Riding Tips For Long Engine Life – IMPORTANT
Do not over rev your engine as you may cause damage to valves & piston. This is particularly applicable to the larger displacement
engines from 140 upwards. Under load the engine is capable of revving into major valve bounce that can cause permanent damage to
your engine. If you feel the power dropping off or start to hear valve bounce it is critical that you change up a gear or ease off the throttle.
Valve bounce is often confused as being a rev limiter. It is not a rev limiter it is the sound of the engine being mechanically incapable of
closing it’s valves fast enough & thus cannot increase it’s own speed further. The resulting effect in extreme cases in the piston hits the
valves & destroys the top end of your engine. Very expensive.
Do not stamp through the gears – always use the clutch. If you do not use your clutch you put excessive load on you gear selector forks
which will wear out very quickly resulting in slipping, jumping or missing gears. In extreme cases, you may bend the selector forks with
the same effect.
If you miss a gear do NOT stamp into gear from high engine revs. Your gear shaft is now rotating at a very high speed, if you stamp into
gear now, your gears will have to mesh at VERY different speeds. This will cause rapid wear or damage to your gear teeth reducing the
life of your gearbox.
Do not drop your clutch heavily, or slip it unnecessarily. Dropping the clutch puts immense strain on your drive train components. Slipping
your clutch will cause excessive wear to your clutch plates.
