*** This is long cause I wrote down everything I did ***
***scroll all the way down for the skinny version***
Took the bike out of storage and lo and behold it had problems starting.
I followed the winterizing page from ninja250.org the only thing I didn't do was drain the carbs (because I didn't know how to remove the fairings in fear of breaking the plastic bolts)
Got some fresh fuel in it (learned how to siphon in the process ) cranked it and it idles roughly under 1k. Pulled the plugs and saw they were a bit black so cleaned them. Figured somethings a bit plugged up so got some sea foam (damn napa is expensive...) siphoned out the fuel again and this time injected sea foam into the carbs. Cranked it a bit to let it get in let it sit for 1 hour then added some gas and cranked it again but nothing changed except it was now puffing out white smoke... (I figured out how to remove the fairings also after youtubing various ninja vids.)
Day 2 (really was 1 week later cause I had work and no free day)
Time to learn how to clean carbs! Got the service manual and finally figured out how to remove the carbs (there is a couple of steps you don't even need to do...)
Opened the carbs and they are very clean... but figured ok somethings gotta be wrong so pull out the main jets. They are clean no visible dirt and holes are clear in the light. Just to be safe I clean the holes anyways... Reassembly and damnit it still idles roughly and dies with throttle
Figured I should change the plugs (yes I know I did it backwards...) since it was a little black looking.
New plugs in crank it no dice same thing.
So then played around with the choke wire and found when I push the hinge the wire is connected to it revs up and lets me throttle. (It has like 1 cm more of choke then the lever allows)
So reading all the post it suggest it's running too lean so off the carbs go again because I didn't check the pilot jets >_<
Checked the float bowls they looked clean and nothing out of shape, pilot jets also clean and clear... rechecked main jets just in case.
Then checked the carb sync by eye and notice no difference. Then noticed the mixture screw on the right side stuck out a bit. I go WTF are you kidding me... so drilled the plug off and reset it to factory 2 1/2 turn. For good measure I did it to the other screw.
Start her up and it idles better and I can actually use throttle. So figure the job is done
Suit and take her for a spin then notice it's a but sluggish in first gear. Then it picks up and I can rev up and change gears. Ride around the neighborhood then stalls Start her up again and get her 1 block away from home and then BLAM! she loses all power and dies. Pull to the side of the road and try to start her again and no dice it ain't happening. Ended up pushing her home
So i'm out of ideas on what is crapping out. Besides changing the oil but that shouldn't affect the low revs should it?
