250EX Great Bike - Hard Cold Starts
#1
I just bought the wife a new 250EX. This things is great. Perfect bike for her. There are only 2 things I want to get some feedback on.
1.) When the bike is cold, pulling the choke out and pushing the start button does not work. I have to give it a little gas. Once it starts, it will not idle unles I give it some gas. Once it is a bit warm, it will idle. I tried adjusting the idle, but found it was in a good position. If I went too high, I lost all throttle response (it woudld die if I gave it gas too fast). Any ideas?
2.) I don't think this is related to the first, but it may be. The engine is not real smooth at full throttle (second gear). Going to third, even less power. I wanted to keep the RPMs up for tackling some hills, but the motor sounded like it might be hitting some sort of rev limiter. It seems to be real choppy up high in the power band.
I am much more diagnosis-savvy with 2-stroke mx bikes. This sound much like a jetting problem. But I have been wrong before.
Any help is welcomed.

Our Recon also needs fiddling on a cold start, but they're known for it, no biggie, it runs in the family. It at least coughs on the first hit, my Rancher maybe not. (Now that I've finally learned how to use the carburetor heater it's much better though). I believe Honda has tuned them both for bottom and mid range. The 250ex is a Recon underneath, so shift sooner, keep it in the range it likes.
I'll gladly accept a few extra minutes at startup for the way they run afterward.
