just gave it a test- still sooting up the plugs quite a bit.
I'm not sure why yet, float level was pretty close and original jetting.

But I just discovered the ones someone put in were a bit colder than original. So I'm getting some hotter plugs and perhaps that will solve most of it.

Did you solve the fouled plug issue? I have been out of town and just got back. So I have not tested yet.  I should have it all back together and ready to test today. After some reading- I have heard of other bikes that were also rich with stock settings. The needle drop will certainly lean out a b...

The bike sat quite a long time. I’m not sure when fuel was in it, or how long ago. When I first put some in, one carb overflowed- a tap on the bowl stopped it. But the plugs also are very black and tend to foul. So I popped the carbs off- cleaned out bowls (just a little bit of stuff in there, prett...

The result is outstanding.
Very satisfying to finish a project like this.

Another break-in ride today.

Two darn cool bikes!

Need to line up all the Benelli 250s (too bad I don’t still have the 250 ‘egg’)

Comso only brought 8 of them into the country. There have been a few more around direct imported much later. You will see another around before long- but I won’t spill the beans. One of their 60s 250 or 350 road racers would be super cool. But since they were factory only bikes- cost would be incred...

Another picture.
I changed oil (very well original- and while base oil is still good, additives can go bad)- installed a new agm battery and it is running great.

I’ve been looking for years. I found a new 1980 Benelli 250 quattro (four). Original 44 kilometers.
Freinds sold it to me for a great deal.

This is a new bike, from 1980.
Next to my 250 2C (2-stroke twin), which is small. This is even smaller.

I am waiting on handlebar on/off switch- but did a temp wire, then kicked it over. Nice hot spark.
Good start.

After I finish wiring, I will see if I do a test timing by kicking.
