Took my kart out again this weekend for a dust off.
It's an "arrow" brand 125cc from Australia. As usual, much was learnt from the trial and error while following rather vague instructions from manuals and online sources, while attempting to service our karts.
Order of the day:
1) change coolant in the radiator
2) change the counter balance gear oil
3) wheel alignment
4) fire her up
5) test drive
6) go for "Wine and Dine" BBQ
This is where, on the engine, you are required to top the engine oil. On the side of it, there are 3 screws. The bottom most is to drain out all remaining engine oil. Depending on the model of your engine, one of the remaining 2 allows you to level off the engine oil in the engine after you have flushed and topped it off with new engine oil.
Ideally, a funnel would have made the job easier and less messy but hey, meeting up with friends in an oil soaked, white T-shirt and greasy hands gives off a manly appearance.
Pictured here is the aforementioned screws on the side panel of the engne block which controls the amount of engine oil inside. Pictured here are the 2 relevant screws, with the remaining third hidden from view behind the bar of the kart frame.
Removing either of the screws allows the engine oil inside to flow out until the desired level has been reached.
Flushing the radiator was a little more straight forward. Basically, the radiator has to be drained and then flushed throughly with some of the new coolant liquid which you intend to use.
Aligning the wheels took a little more time than the other tasks.
First, we had to determine if the front tyres were toe in or toe out. The back wheels had to be aligned to the end of the axle as well. More in pictures in the next post on this.....

someone mentioned that the oil level in the counter balance gear affects the ability for the rotax max to idle properly. do you have problems with idling?
A gear-driven counterbalance affects the engine's ability to run smooothly. It balances out the forces created by the movement of the piston within the engine. Consequently a damaged counter balance gear will result in vibrations in your go kart that renders it unoperable. Also, it enables the movement of fuel to the carb via a small membrane pump. A damaged counter balance gear would then affect the entire go kart's operation and not just the idling.
