cb's weber idf update kit
Former Member
what do you guys think of this update kit for the 40 and 44 idf carbs? do the horizontal jets and larger venturis really make a noticable difference in performance? are the claimed 12% gains valid? -Antonio

I cannot attest to the update kit but CB does sort out diff ways to get legit performance power increases. The 12% increase is probably true for their engine & yours too if it is very close to theirs.
The kits work fairly well; there are no "horizonal jets" but rather a change in the auxilliary venturi. You will need to re-jet, and if you don't have an accurate air/fuel meter that can be an expensive, tiresome, and sometimes inaccurate process.
