I have just installed a 40 Lectron on my dirt bike and was wandering what everyone else is running for needles.
its bone stock except for a FMF woods pipe. My dune bike has some other mods and I run a 44 with a 7-2 needle the only extra needle I had was a 5-2 and it seems to be on the lean side I am up to a 85 power jet and turned way in on the needle.I am around 750' elevation.
