YES YES YES, what another starting problem thread, ya buddy! well i did a search i didn't find anything that was similar to my problem so here i am 2008 drz400sm specs/mods: 3x3 mod, k&N filter, JD jet kit, Yoshi RS4 exhaust, removed clutch & kick stand switch, Trail tech X@ headlight and a bunch of other cosmetic mods. Issue: this started happening this year late spring ish and seemed random, try to start bike, it turns over but no fire. I try this until the battery dies and hook back up to tender. Later that day/evening after work and it will fire up no problems. I Changed Spark plug (there is a spark) and oil to see if that was the issue and this still happens and it seems like it happens on cooler mornings. Other than the starting problem the bike runs great, no other issues, all the mods i have done were done the last few years, none this year so i believe all my jetting is spot on for elevation (it does pop sometimes) other notes, all lights works, the starter works because you can hear it trying to turn the engine, there is gas, battery is fine because i do have it on a tender in the nights any ideas!
