All carbs are built to order and have a 1 week lead time
“I have a 2000 kx250 and 2001 kx500 that have a 40 and 44mm lectron carbs on them. I race all around the country and at different elevations and air densities. Going to a race and knowing my bikes are going to run flawlessly because of the Lectrons makes it one less thing to worry about on race day. Both of my bikes that have Lectron carbs have also earned me AMA Amateur National Hillclimb titles. 2011 on my 500 in Oregonia, Ohio and 2012 in Bay City, Wisconsin on my 250. What's even better, is that for me, these carbs were ready to go out of the box, no tuning or anything. Just an overall great product.
