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.
It's all about programming the computer these days although a K&N
sucking cooler air will help performance and fuel economy but you will
need a pipe for that. And maybe a new throttle body. And maybe a new
exhaust...
It looked like that's what Tim had found for his Jackal, at a cost of close to $1000 bucks. But hey,
all the performance improvements added together would get him about another 50% improvement in
everything!
