Hi this is my first time here. I live in America and have a 2005 yamaha Zuma. I installed a stage 6 racing 70cc cylinder on it. My problem is I cannot figure out where to get the parts to rebuild it. In specific I need a piston, ring and bearing. I cannot read german and they do not have pictures on scooterattack for these items. Can anyone help me out with part numbers?
 
Which piston size do you need? There are A, B, C, D etc.
If you buy a piston, you 'll get the ring with it. Which bearing do you need? A small-end bearing?

Is there an easy way to tell which piston I would need? It came with an athena piston I saved the box. I need the bearing that is up inside the piston.
 
Then you need a small end bearing. In scooter-attack there is a Stage 6 small end bearing under the cylinder topic. Measure the pin, whether it is 10mm or 12mm. And order the right one.

Thanks for the info, it is a 10mm. I just wish scooter attack had translation I have to manually translate everything. Also about the different piston size is there a way to tell? can I measure the piston to figure it out or is there an easier way?
 
you dont have to order from scooter attack. just measure the bearing (or it says what size they are on S-A) and theres pretty 1 or 2 sizes for 10mm small ends. Prolly even just order from moped hospital or somewhere in the states.
 
There should be a letter on your piston. Normally you'll need a piston with that letter.
You'll need a small end bearing. It's best to take one from the same brand as your crankshaft! Some bearings don't match the conrod diameter.

Ps: there should be a button to put the SA website in english
 
thank you all for the infos I will take off the head when I get home and see what letter piston I have.
