I have a 4 mm drag port stock cylinder,I have 38mm straight lectrons with power jets..What depth do the needles need to be and what size do you drill the jets out to?850ft elevation..Should I run pumps also?,ThanksJB

With lectrons you dont need to drill anything out just change the needles to a PE-1 from packard.

Start off with the needles @ like 45mm which is really rich and adjust out from there.

I am not running any bowls on my 350 with the 36/38 lectrons and i havent had any problems out of them.


Also you could pm Bubba297 or Camatv or dajogejr they are all really good with lectrons.

Lowbuck, do a google search about lectron tuning. You will find the reading very useful. A lectron only has 3 basic adjustments, the idle, the needle, and the powerjet (or powerjets) I always recommend a double powerjet setup, unless you have a packard or Dave Moore style. On a stock bowl I also like to remove one float for more fuel capacity. Once you get the carb on the bike, there is no need to ever pull the bowl unless there is a float valve or leak problem. They are simple yet very effective carbs.

Unfortunately, the main website has great info but is down at this time. Check later...
The official site of Lectrons is:

Whether or not you need to run a fuel pump depends on the needle and seat. Remove the float bowl, remove the needle and seat.
If it has 3.3 stamped in it...it's a fuel pump needle and seat. I have both, gravity and fuel pump N&S at the house, I'll have to look for the number on the gravity fed set.
