I have a 2006 Suzuki ltz400. i bought it off some kid upstate and it ran when i tested it at his house. i brought it back to Long Island then it wouldnt start. it doesnt electric start to be more specific. Itll start if i pop the clutch in first gear but it doesnt idle, it dies. only does this when the motor is cold, when the motor is warmed up, itll idle. so i took it apart the i found that it had a blown headgasket. i replaced that and now it still doesnt start. i checked the timimg and its TDC on the bottom and top. now it cranks very strong and the compression is strong but it still wont turn over. its popped a couple times but it doesnt run. i cant seem to figure it out, i need help please.

 

valves 99.9% of the time. mine wouldnt start cold unless you pop start it wouldnt idle very well either. as soon as it was warm idles fine starts right away. my guess is your intake valves are at 0 lash. do some research suzuki central has everything u could ask for when working on ltzs or kfxs.

 

That's the same issue with mine. When I checked my intake valve, it was at 0 lash. I'm gonna get the dRZe kit and ferrera valves. Thanks a lot man
