2.      To prevent exhaust from snapping at welds, use the exhaust strapping kit that some kits come with if necessary. Alternatively, you can purchase 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.

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.
