y2kbanshee9187 Posted February 15, 2005 Report Share Posted February 15, 2005 I finally got my bike running. I replaced the spark plugs. I thought it was the carb before so I took it off and played with it a lot. Now that I have done that it runs funny. I have a lectron fast by gast carb. One little turn of the needle and it is idling way too high and one little turn the other way and its idling way too low. Also when the choke is in the off position it acts like its on. When its in the on position it acts like its off. Therefore, I have to ride it with the choke on to get it to run right. If I have the choke off it will rev too high in neutral and then when I put it in gear and pop the clutch it will stall. Quote Link to comment Share on other sites More sharing options...

Fireman-hott Posted February 16, 2005 Report Share Posted February 16, 2005 Go up on the pilot and main. If it runs right with the choke on than it means you engine needs more fuel when the choke is off. Pulling the choke out infuses more fuel into the engine. Revving way too high is lean. Try going up on the pilots and report back. one maybe two sizes should do. Quote Link to comment Share on other sites More sharing options...
y2kbanshee9187 Posted February 16, 2005 Author Report Share Posted February 16, 2005 What do you mean by going to the pilots. My carb is different than the stock ones. I cant really adjust the jetting. I can adust the needle by turning it and screwing it in or out but.. Quote Link to comment Share on other sites More sharing options...
Im-Loving-It 69 Posted February 16, 2005 Report Share Posted February 16, 2005 No matter what type of carbs you have thay all have mains and pilot jets. You just need to find it, trust me its in there. Quote Link to comment Share on other sites More sharing options...

05bansh Posted February 16, 2005 Report Share Posted February 16, 2005 With the Lectron Carbs, the jetting is external. Its a screw on the top of the carb which you can richen or lean it up. If you are not able to dial it in with the screw you can change the needle postion still, that should give you more options to play with the screw.

I go one turn one way and its idling too high, I go back one turn and its idling too low, and I adjusted the screw on the outside too, its where the throttle cable goes in.

You just need to find it, trust me its in there. 324466[/snapback] how much you wanna bet?? ill bet you 5 grand right now that you are wrong...lectrons do not have jets... your lectron carb should have an idle on the side. dont try to adjust the idle with the needle. one turn on the needle makes a huge difference. does your carb have an adjustable power jet? on top of the carb is there a little knob you can turn?? should be right behind the throttle cable. thats for top end. for your bottom to mid range you use the needle. you need to get the needle in there and get it idling with the idle screw, then you can adjust the power jet...do you have a picture of your carb?? the idle should be a screw on the side...

locogato11283 Posted February 17, 2005 Report Share Posted February 17, 2005 i just now read it again and it sounds like its way too lean. if you have to choke it to get it to run its not getting enough gas. screw the needle up a few turns and see if it will idle without the choke on..what do the numbers on the needle say? itll read something like 4-2 or 6-2..what do you have in there?

My bro has a Lectron, I have watched him work on it many times. Also on the main screw (power jet screw) you should not be turning it in whole turn incerments. Try turning it in 1/4 turn incerments. It wont be as drastic of change, hopefully you be able to get it dialed in that way. let us know. Quote Link to comment Share on other sites More sharing options...

toolman Posted February 17, 2005 Report Share Posted February 17, 2005 a Lectron carb is by far the simplest carb to jet turn the needle up to make it richer or down to make it leaner.The needle only goes in one way it has a flat machined on one side you may have the wrong needle there are numbers ecthed on the flat side of the needle also if it's lean on the top end you may need to put in a bigger power jet.After each change set the idle with the screw on the side go to Fast by Gast web site all the information you need to jet a lectron is there or give them a call they have always been willing to help me.
