Has anyone out there tried a smartcarb or powerjet on their Vespa? I have one on a horizontal Minarelli build, and I really like it, I was thinking of putting one on my recently acquired Primavera.

There's also the Lectron carbs as well. I remember a few of the Lammy guys were using them when the RB kits first came out. I haven't looked to see how big those carbs are compared to others. There might be clearance fitment issues with the P engines, but with a Smallframe such as a Primavera, I would think there would be more room?

Yes, Lectrons are great. I have a Tillotson powerjet I really like, but there are companies that machine intake adapters for them in Mina applications. I can't seem to find one for vespa.

What would be a good choice for a smallframe w/ portmatched 133 kit & a good pipe assuming I can come up with an adapter? Prices? Links? Tech info for newbs? There's always Google, but you guys seem experienced.

Are we avoiding potential jetting trial & error nightmares?

Currently has a Delly PHBL 24 which seems to work OK.

I'm not too sure how the Lectron works, I do know they are battery operated. The Tilotson has an adjustable aperature in place of jets, so they are externally adjustable with little slide lock levers. I'll pull it and bring it up next time I see you Voodoo.

The Lectron isn't battery operated. It operates similar to the Smart Carb. I'm not familiar with the Tilotson, but the way you describe it, it also is similar to the Lectron.

It all depends upon who you talk to...
My KTM 300 had one on it, and i removed it to put the stock carb back on. The Lectron is supposed to give you better fuel economy, but i think the only way that is possible is my running lean at a certain part of the RPM range. It's probably fine on a off-road only enduro bike, where the throttle varies about every few seconds or so, compared to a road-going 2 stroke that might stay at the same RPM for an hour or so at a time. I hear that some offroad guys love it, while others hate it. Me?...i'm still on the fence.
