So delorto evidently used the save carb for different apps, excusing the needle and jetting. That's interesting. Using the same CFM Venturi carburation for the wide of a genre cc engines. I can't see it but it must have worked...

When I bought the Mille, it was jetted for the USA. Very soon after buying it, I bought a European
jetting kit for both carbs. Also put competition pipes on it at the same time. Turned it into a real
screamer.

I thought of looking up performance stuff for my v11, but I figure it's good enough the way it is. Still comptimplating an MV though...

The pipes, jetting and K&N air filters made a hell of a difference in the way mine ran.

Not really a motorcycle but the same sort of thing happened when I
rebuilt the "Vega" motor in my 75 Monza.
I got a distributor kit and another cam gear that changed the ignition
curve and cam timing, along with a little more compression, a little
overbore and a different carb made that a pretty fast Monza.
I am sure it would not have passed an emission inspection tho ;-)



I can understand how those modifications can make a big difference in
performance. Usually though, they are at the expense of something else.

But the K&N claims have always bothered me. My truck has the 5.4L
engine and came with single exhaust. About 4 years ago I was bored and
I had a dual exhaust system put on it just for the hell of it.
The guy who did the work assured me that I'd get better performance and
fuel economy with the dual exhaust. Bull****. Didn't change a thing.
I then replaced the stock air filter with a K&N. Didn't change a thing.

Since then, I've replaced the dual exhaust with the original OEM single
(was getting tired of the "rumble"). I also tossed the K&N for a stock,
OEM replacement. Again, no noticeable difference in fuel economy or
performance.

Snake oil, methinks.


For the truck I use the Delco filter. Some outfit did a test of various air filters, including K&N,
for the Duramax, and the Delco came out on top. Some outfit in Rhode Island, not GM. I've no reason
to change the truck filter. Here's some of those test results:

Besides, Amazon carries those Delco filters pretty cheap.
