1996dragshee Posted March 16, 2009 Report Share Posted March 16, 2009 word...38s would be plenty.if you're going to gravity feed them you should get oversized bowls or just spend 55 and run a pump.Just a thought Quote Link to comment Share on other sites More sharing options...

b-nasty Posted March 16, 2009 Author Report Share Posted March 16, 2009 Where and how do you hook up a pump. thanks Quote Link to comment Share on other sites More sharing options...
dajogejr Posted March 16, 2009 Report Share Posted March 16, 2009 I'd go 40's all day long. The most common way to use a fuel pump is drill your cylinder for a barb fitting (pulse/vacuum pumps) and plumb it in that way. The intake in front of the reeds is a good spot for the pulse/vaccum signal.... In Lectrons, you also need 3.3 needle and seat. If you use gravity fed needle and seats on a pump, it'll overpower their sealing and drip fuel all over. Quote Link to comment Share on other sites More sharing options...

RadarRacing Posted March 27, 2009 Report Share Posted March 27, 2009 40 HVs, Remember the lectrons are actually smaller than they are listed and sold as which is fine. A 40 is a couple mm smaller than 40mms. My 421 pulled some real nice hp and torque #'s on 40 HVs but if you are dragging only or using alky I'd use 39 or 41.5 pwks. The tuning ease of lectrons is nice tho. Quote Link to comment Share on other sites More sharing options...
