Hi,Good day, I was wondering if someone could help me with my 07 Rm 250 carb?

I did a motorcross race today and the first heat the bike ran perfectly but when I lined up at the start the bike idled and died at the start,there was no funny noises from engine or anywhere.I did check the sparkplug,but it can't be that because I put a brand new one in the night before.

Can it be fuel mixture or spark?

Becuase it does not make sense to me that the bike ran great in first heat and then when I wanted to start second heat it idled and then just died and did not want to start again

what mixture would you recommend?

I use 32 to 1

Um I don't have a recommendation for fuel mixture but maybe try vp race fuels

Vp 110 is good for 2 stroke engines you should try it. I use vp race fuels I mix it in with the gas.

Good day.

We use Motul for our bikes as it is the best we can get...It is the oil that works best with the heat in Botswana for the engines...but thank you.

What would you prefer I do first to get the bike running?must I just change sparkplug first and see what happens and then go from there?

try to get the bike running and maybe change the sparkplug after that if necessary. just don't touch the engine after it's running because that's painful.

If you need anything else feel free to ask and post a thread and introduce yourself.

Thank you got the bike running,I think we just needed to check the sparkplug and see if we can get one with higher temperature...but all good so far thanks.
