Hi, I have a cb400ss 2004 with electric start and HISS security that is very hard to start when cold. No matter where the choke is set it takes ages to get it running and needs 3 or 4 minutes of idling with partial choke before it has any power or will not stall again. Then it is great no problems until the next cold start. I would like to try to enrichen the idle or any other ideas from people. A carburtettor schematic would be good also. cheers Terry
