Ninja 250 help
I'm helping out a friend. He let his STOCK 2008 Ninja 250r sit for 3-4 years with only 933 miles on it. YUCK.
So I have the bike now. I have cleaned out the gas tank(brownish gad yuck!), thoroughly cleaned out the carbs including each jet and port, brand new battery. flushed and put in new radiator fluid.
But I can not get the carbs working properly. First, I could not get the bike to idle. So I adjusted the idle mixture screws and was able to get the bike to idle, but the response from idle was HORRIBLE. A LOT of lag.
So it seemed that it was lean. From what I have read, the bike comes somewhat lean. So I put a thin metal washer on the diaphragm needle, and that helped somewhat, but the bike idled around 4k with the adjustment all the way down. So I replaced the washer with a plastic one about 3 times as thick. The throttle response is great, but the bike still idles at 3.5k with the throttle adjustment all the way down.
I'm just starting to get fustrated with it now. All these changes in idle screws, washers/shims on the needle. The bike worked fine before it just sat for so long. I was really hoping just a douching would help it out.
