complete replacement decompression assembly for vespa piaggio mopeds! for stock and polini heads. some malossi heads use a special smaller decomp valve so make sure you have a stock size (9mm) valve head.

comes with valve, lil cotter pin, top piece, cups, spring arm thing and valve spring (not in photo)!

don't forget to lap the valve seat upon installation or else it'll leak and life will not be so fun

5 of 5 All parts NOT included November 9, 2019

Edit: David just sent me out the missing piece with super fast shipping, 5 tacos!

Sooooo, mine came with three little cup washers (1 too many) and NO TOP PIECE so I literally can't run it. Looks like I won't be ripping this weekend after all. Thanks treats! Going to to contact ya'll via email and I'm hoping this can be fixed...

5 of 5 Decompress in style with new parts. July 3, 2019
taco eater : Mason Shreve from Carrollton, OH United States  
I got this to go along with my Malossi 64cc Bravo kit on my Si. The valve, spring and cups are great, the valve had a couple burs on the eyelet, nothing a little emery didn't fix. Don't forget to lap this in or she gonna leak. THIS IS DIFFERENT THAN AN SI ARM, but it is the one you need to put a Bravo head on it, the geometry is different between the two, and the SI arm will hold the decomp valve open on a Bravo Head.
