Vespa Gurus, stock oil injection pros and cons!

Just p/u a Grande with oil injection it it seems to be working great. I know many people say dump stock oil injection and mix but I was just wondering how the Vespa's are considering this is the first I've sen.

You'll probably get more advice on the moped repair forum. I advise premixing if you are going to upgrade to performance parts. My oil injected Grande soft siezed because 1) a vacuum built up in the oil line due to a plugged hole in the oil tank cap, 2) greater air flow means a need for more fuel/oil which may not be possible with oil injection meant for stock performance.

That makes sense, I guess if it were mine I would use it, maybe replace all lines if they look questionable, and check those vent holes! :) the ease of refueling anywhere would make it worth it to me. Vespa is a trusted name to me.

Yeah just premix in a can, it eliminates a serious potential problem.

mike run the oil injection cause it will aggravate people at a rally just like mixing in the tank does
