Hi Gang,

I picked up a 2007 250 with less than 3K miles. It had been sitting for a long time.

I rebuilt the carbs, and the bike starts easily. It will start without choke on these warm days we have been having.

When the bike is idling at 1500 rpms, and I blip it up to 3,000 or so, the idle hangs up there a bit and kind of slowly drops back down to 1,500. It feels like a delayed reaction as it returns to 1500ish.

If I rev it up to 4 or 5K and let it drop back to 3Kish, it seems to come back down in a more normal fashion.

Bike screams nicely when up in the higher rev range. Seems to be running fine when I do that.

Any input is appreciated.

Thanks All!
