Asso Pistons
« on: November 30, 2021, 05:46:34 PM »
The only new pistons I can find online for my V7 sport are these old stock Asso pistons.

Does anybody have experience with these?

yes, fine cast pistons. Had some in a used endurance motor I bought from John Hoffman. It was 88x70 for 900 I think. I think one piston ended up disintegrating on the race track in an AMA Pro Twins race (topeka?), but it was being used (abused) well past its expiration date. I wouldn't hesitate to use them in a street bike.

These? https://www.ebay.com/itm/173694313413 If so, the domes are a different shape than the originals and the compression will be higher.

Guzzitech has V7 Sport Gilardoni kits for a good price: https://gtmotocycles.com/products/gilardoni-piston-cylinder-set-82-5mm

FYI, all of the old Guzzi pistons I've had my paws on either were stamped ASSO or MONDIAL. 

Would those higher compression pistons be a bad thing? That is quite the dome on those. Nice opportunity to build a hot V7Sport.
