Hard Starting

[Stein2088]

i recently purchased an 01 400EX and it has a hard time starting when its cold... (just the engine) even when its fairly warm or cold outside it has a hard time, but once she's warmed up she starts rite away... any ideas???

Thanks Nick

a lot of people on here recommend going up to a size 42 pilot jet.

see here for the article on how to do it:

I picked up a new pilot jet for mine but haven't put it in yet.

good luck!

My 00 is cold blooded also. If its slightly cool outside it takes a bit to get warmed up. Go up one size on pilot jet and that should help.
