Ok, so I'd picked up this 250R about 45 days ago and it ran perfectly when I got it.

I don't really know how to ride, I'd bought it to learn on (since got an uber-cheap 2003, which is why the 08 is for sale), but I was going to sell the 08 yesterday so I fired it up and puttered around on it. It had sat, unstarted, for 45 days in a cold garage, gas in the tank, no fuel stabilizer.

It's running okay after warming up, but when I really want to give it throttle it will sometimes die out, and throttle delivery is jerky at best.


It has to be something caused by sitting, but does anyone have any ideas?

Do I need to take it to a Kawi dealer, or should just riding it around fix everything? Maybe drain the gas and add new gas? Is there something dumb that I'm missing, given that I don't really know what the hell I'm doing?

I'm kind of at a loss. The bike is still under warranty, but this has to be some stupid thing, as it was totally perfect a little more than a month ago.

 

sounds like the carbs need cleaning

 

Obviously there's no injector, per se, on a carb'd bike, but would running some injector cleaner through the gas tank have any positive effect?

 

it might help... sumtimes that works sumtimes it doesnt

 

edit- no, i'm dumb, 250r's are not fuel injected.

is the bike fully warmed up when it's stalling? cold weather can attribute to it running like crap too.

regardless, i'm sure putting around on it for a good 30-45 minutes should resolve any issues.

 

^ +1 on what blackout said

Mines garage kept too, and if its cold outside it takes a bit to warm it up first and jut get everything going again. let us now how it goes.

 

guess im the only one that reads the WHOLE post.... like i said check the carbs

 

Carbs. Not like no one has said it before. When I got my 600 mile service on my ZZR, the tech asked me if I was going to store the bike through winter or keep riding. When I told him that I was going to try and tough it out through winter, he told me to make sure to use fuel stabilizer and run the carbs dry if I were not going to ride it for two or more weeks. I don't know too much about motorcycles, but I'm going to believe what he said. He told me that if the bike were to sit longer than two weeks without being fired up without being stabilized or ran dry, that the ethanol in the gas would mess with the carbs, resulting in me having to take it and get carbs worked on or whatnot.

So my guess is the carbs are messed from the fuel sitting in them for so long. And my only source is what the motorcycle tech told me.

Next time if the bike sits for an extended period of time. Make sure to run the bikes at least once a week, and get them up to operating temperature for about 10 minutes, then cut em off. Repeat weekly.

I'm going to feel retarded if everything I wrote was complete nonsense, hah. :-P

 

OP

I dont think you have gone so far as to gum up the carbs. For the helll of it I would just add a little seafoam to the tank. The main problem is that I dont think you are warming your bike up long enough. The new 250s are super lean down low to begin with so that helps explain a little bit of the stuttering and the cold weather and it sounds like your problem. I say let it warm up a bit longer and report back.

 

+1 on the seafoam
