I put this on my 1977 Vespa Ciao and it fit right onto the motor case with no issues. The decomp valve fit right on perfectly for me when using the vespa piaggio olympia 43mm kit with head - 12 pin. The carb worked on the first pull after putting gas in it, but I did make sure it was 1.5 turns out from screwed in. The pipe sounds great and is fairly loud so I love it. The race crank has a bearing instead of the stock bushings with oil hole so it gets juiced. I did not have to do any woodruff key filing so that was good.

Good parts, needs a head

I've had sealing problems using stock heads on DR kits in the past, the port that goes from the decomp in the head-into the cylinder- comes too close to the cylinder bore and will blow out causing air leaks.
I would say 100% you need a 43 mm head with this kit.
