IMPORTANT (Please read):

1.      In order to create a suitable steal on the intake and stop any air leaks, please do not remove the plastic insert or o-ring that comes with your carburator.

2.      An exhaust strapping kit will be included with every engine kit. Please use this to avoid exhaust snapping at welds alternatively, you can use a JB Weld Metal Strapping Kit.

3.      To prolong the life of these components, it is advised to clean and regrease the clutch arm, bucking bar, and bevel gear every few weeks.

4.      Fuel/Oil Ratio recommend by manufacturer: New Engine (500km or approx 3-5 tanks): 20:1 or 50ml of oil per litre. After Break In: 25:1 or 40ml of oil per litre.

Using a different oil ratio than what is advised may speed up engine wear and cause engine seize. Don't assume the ratios instead, use a two-stroke mixing container to measure the oil. Our engine kits come with a 30-day warranty from the date of delivery. If you use a different oil mix ratio, this warranty will be void.
