Malossi 47mm 70cc Piston Replacement
« on: September 07, 2016, 05:11:29 AM »
Popped a circlip last night while riding.. A ping noise and she slowly died. Piston and cylinder are toast. I have a spare cylinder but no piston.

Treatland is out as are all the other US scooter parts companies I tried.. Racing Planet has it but it's in the EU warehouse.. I'm not waiting a month. I'd rather buy a whole complete kit from Scooterpartsco.

Dynoscooter has one but it's listed for Malossi 31 7200. My kit is a 31 9987.

A search of 31 7200 tells me that's for a Dio kit. Think it'll fit mine?

This link http://www.scooterloungeonline.com/product/M%20319987 says piston # is 347036

So this should be the piston

https://www.amazon.com/Malossi-34-7036-Replacement-Cylinder/dp/B0057X6N0G

Thanks I can confirm that is the correct piston. Identical to my original.

For future reference for others who may need a piston get the 347036 for Dio. Malossi makes like 8 different model 347036 pistons. 347036(a), 347036(b), etc. Different pin sizes, chrome rings, etc. combinations.

scooterpartsco has pistons for kit 319987, very reasonable price too.  Cheers

1st and 2nd usually have an unfair advantage.  3rd is usually the best, can learn the most from.  paraphrased from Don Quixote, over 400 years ago, still true today
