SOLD Mikuni Solex 40s

Postby 2mAn » Wed May 17, 2017 4:46 pm

Got these in a trade and really dont think I will use them. Actually Im just trying to save myself from myself. I immediately started looking at the 1600 manifold for these and searched for a 1600 to put them on. Something is wrong with me,

They are missing the jets, jet blocks and the fuel line banjos. Still a solid place to start, especially if you have already have some jets. These seem to be 600-800 for good complete sets and Im guessing theres about $200 to be spent if you have to buy everything thats missing so Im asking $400 obo . SOLD

No reason to limit them to a 1600. Tuned and setup properly, they work beautifully on a 2L too, U20 or stroker. In some ways better than 44's.

In other words, you should be looking for a U20.

I don't know anyone who has engine dyno'd a U w/40's, but lots of other 2 liter displacement engines have used them and I've used them on the U with good results. (have a set on one now) Nice idle and powerband. Less bog than some 44's I've driven (that is highly engine and tuning dependent)

With a otherwise stock B cam U20, I'd estimate the HP to be almost identical to 44's up to about 6k rpm.

Remember that the air flow limiter in the PHH is the choke (outer venturi) size up to a point. If you are running 34-37 outer chokes 40's will do great for a street car. The 40's may make a little more torque through the typical power band too.

If your U20 is big bore/stroked or you are trying to run frequently in the 7500-8k rpm range, you probably want 44's. Reality is that most drivers aren't beating their engines at 7500 typically, but some guys do.

I'm not affiliated with the seller, but these are a pretty good buy if you can work on them yourself. These particular 40's use the same exact same linkage as late 44's. (not all do) //cheers.

Stan Chernoff has them I believe,
Dave Premo certainly has them and every part you could need!
Mike Young, Ross and Don Morrell can probably set you up as well.
Paul Wells has a great collection of carb parts for solexes and SU's

I have new or used 40's available. They are typically a bit less cash than 44's too.

My linkage kits are available from all these vendors too! I even have a linkage kit for the narrow body 40's (which work great too).
