Honda CB400 takes forever to come off choke...

[Guest]

Any suggestions for what it may be?

Thanx

Can we have some more info please.

How long is forever, what conditions, what are the symptoms if you come off choke to early, what are you comparing it against etc.

Takes around 5-10 minutes to warm up - if you drop the choke beyond mid it just sputters and trys to die or dies.

I'm comparing it to a mates CB 400 Super Four (both are Super Fours) on which we can drop the choke to nothing after a minute without any grumbles (this is standing still at the end of the drive last night)

We started her on a warm day . . .

I've cleaned the carbs + its a 1993 bike not the older type and therefore called the CB 1

Thanks, OK sounds like its the carb setup, I would reset the carbs as per haynes manual and then adjust. Might be worth checking the carb balance as well (sorry cant remember if the super4 is multi carb).

Have you checked air filter as well? is it standard and clean, if its running a free flowing filter this could have been done without reseting the carbs.

Would do but Mr Haynes won't produce his manual for my trustee stead - I've found a cd version on E-bay tho so I'm going to give that a go

I'll check the filter when I get five - gotta go hunt for some food first...

Thanx for all the help mate and I'll let you know how things are a goin
