Need help with cold start

[brains]

Long story, but my 05 300 now has a 250 barrel and piston in it.

It will not kick start cold, jump start it down the driveway and it starts in half a meter.Once warm, no problem with kick starting, first kick.

Any ideas? I'm think carb problem?

For what its worth I have an 02 ec300 that has the same symptoms. I have only recently "learnt" how to start it when its cold.
1) Fuel on - choke on
2) Kick over slowly -twice DON'T touch the throttle
3) Give it a good boot - still no throttle

It lives!
hope this helps (Ex Mooi River RSA)

Thanks Harry,I'll give it a go.

Ex Mooi River - where are you now?

In New Zealand

NZ looks like there is some nice riding there by looking at my bother in laws pictures.

The cold start method - no throttle works like a charm, just have to get rid of the old habit of giving it a twist first.

Thanks

Happy to be of help, look me up if ever you are in this neck of the woods.

I'd bet your pilot/slide/needle are on the rich side. Mine used to take a hefty boot to fire until I started leaning down the pilot (and main 1 size). It was much better, but now with the LTR needle it takes a light hearted prod to fire on the first or second kick (when cold, 1 when warm) and the choke can come off after a couple seconds. No more choke on/off fiddling while warming up.

Just from my little experience, but if it is tough to start cold, as the temp drops. I usually bump up the pilot. It is also a good idea to bump up the main if getting run hard & going from 80 degree weather to 40 degree. Actually there is a rule of thumb for every 10 degrees, but some carbs compensate better. Then go back down when the outside temp warms up. I am sure kicking it over real slow twice would help that situation out in more ways than one.

Put the bike in second gear and rock it back and forth a few times. The piston will suck a nice change of fuel into the cylinder and will start in the first or second kick. I trick I learned from a old timer!

And what kind of condition are your reeds in?

 

[brains]

Just about brand new.

Mine does the same thing ,but it needs top end/reeds.But even when it was fresh,before you kick it turnit on it's side 'till gas coms out of the o-flow tube,coke it and kick.Old 500cc trick!

I usually just kick my bike slowly through it's stroke 3 timeswith the choke on and no throttle and then just give it a good kick. Both my 300s will usually start on that first big kick unless the gas is old.
