If there's no arrow instead has 3 lines should those be towards exhaust?

To fully understand why the piston must be facing a certain direction! This will help you for the future whether the piston is marked or not. The piston has 2 small ring Pins that locate the ring ends. These Pins are positioned so they slide on the cylinder surface without making contact with the ports (cylinder openings). So let's insert the piston in to the cylinder without the rings. Now line up the Ring Pins and you will notice if they slide over a port or not. I usually mark the top of the piston inline with the pins so you can easily see the pin position as it moves down the cylinder. If they do not contact the port then you have the correct positioning of the piston.✌️

Hi! My snap ring broke off inside its housing. How can I get the remainder out? Its holding the piston pin in place. I really need help. Thanks

There is a small tool with an angled picker point that you can use, most local tool stores. Push the clip to the insertion and remove.

That's definitely the best way to install a piston. I used to put the piston on the crank first. But this is a better way when you don't have a lot of space.

If we replace the pistons in a scooter can cause problem with power after ?
@scooterstreetau3 жыл бұрын
No, if the correct piston has been installed, and in the correct manner there should be no problem.

Hi there, Just wanted to ask a quick question: Does the 70cc Malossi Sport piston rings have any particular position where you placed them on the piston as I cannot see no markings at all on both of the rings. Thank you.
@scooterstreetau3 жыл бұрын
Can go in any position, first or second ring groove. The mark must be facing the crown of the piston. See video timeline 0:57
