DR 75cc kit

Hi. I have a DR 75cc kit and I was wondering witch main jet and spark plug to use?

My Vespa is a PK XL2 with the original carburator

Hi dude !

 

My recommendation would be:

 

Jets:

70 - 68 for run in and 68 - 66 after run in.

The correct plug would be a Bosch W4AC

 

 

cheers
