locogato11283 Posted June 8, 2005 Report Share Posted June 8, 2005 get some bigger carbs while you are at it loco! 379189[/snapback] nah, i think bigger carbs would be too much for the hillclimbing. the 35s seem to be the trick right now...

John19 Posted June 9, 2005 Report Share Posted June 9, 2005 What do you guys think about lechtron carbs? I really want a set and have been reading about them for a few weeks now. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted June 9, 2005 Report Share Posted June 9, 2005 What do you guys think about lechtron carbs? I really want a set and have been reading about them for a few weeks now. 379606[/snapback] i have a 44mm lectron with powerjet on my cr500 banshee. i guess when you get them tuned in they are fine. i went thru 2 different needles before i found the right one. the needles are 30 bucks...its nice to not have jets and shit. they are easy to adjust. it just takes some time gettin used to them. it would kinda suck to have to jet 2 but if you have a dyno in the area with air/fuel sensor id tune it in on that.

9603banshee Posted June 9, 2005 Report Share Posted June 9, 2005 I also have a F.A.S.T. Racing 350 cub that I'm finishing the heat cycles on......I'm planning on dragging and duning with it so I have an 8 over swinger on it, jetting is way fat right now, and it'll still standing up in the first 3 gears easy, I haven't got over 3rd yet, but I can't wait to get on the dunes, Jeff knows his shit that's for sure Quote Link to comment Share on other sites More sharing options...

sandgrencivic2k1 Posted June 13, 2005 Report Share Posted June 13, 2005 What did it run you for the 4mm, cheetah cubs and porting? Also does Jeff at F.A.S.T racing have a website? I am thinking about getting them but money is sometimes hard to come by. Quote Link to comment Share on other sites More sharing options...
