Hi all.....

My friend has a 03 Z400.Her just a couple of months ago it started to become hard to start when cold.(sits for a few hours or overnight)It will just crank and crank.Sometimes it sputters but that is it.Here is the strange part.If I pull start him the bike will fire up within the first 20 feet or so and run fine.He can ride it the rest of the day and it will restart using the elec starter as long as it dose not sit for a long time.We put in a new plug and checked the carb but can see anything.could it be a compression problem?I don't know it runs real good after ya pull start it that is thee thing that is stumping us.We need some help.............



Thanks in advance........
