- Re-Adjust throttle cable & clutch cable if required

RIDING TIPS FOR LONG ENGINE LIFE - IMPORTANT
- Do not over rev your engine as you may cause damage to valves. This is particularly applicable where an inner rotor kit is used. 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.
- It is good practise to carry out the above checks on a regular basis, ideally each time you ride your machine. We advise an oil change after every 10 hours use.
- Do not stamp through the gears – always use the clutch.
- If you miss a gear do NOT stamp into gear from high engine revs.
- Do not drop your clutch heavily, or slip it unnecessarily.
- Do not allow your air filter to fill with fuel – this can occur by incorrect float height setting – see above, or the bike falling onto its side.
- If the engine back-fires while the air filter is filled with fuel, it may ignite
– check air filter regularly while riding
