Not getting the full potential from modifications

The jets in those carbs are standard 5mm(DelOrto) you can find on ebay or you can go to www.treatland.tv, do a search for delorto jets and they will sell you any size you like. either in groups or individually. I think thatsdax sells them also.

SBP has them, too. $2.50 a piece but the shipping adds up, buy several at once to save some money.
You could also get a set of numbered drills and a soldering pencil and do it yourself.
