New '05 EX250F - Issues: Front Alignment, Steering Wobble, Throttle, Carb, Petcock et
Picked up a mostly clean looking '05, 4k miles, $1200, believe from original owner, garaged.
Needs a bunch of things, wonder if it's worth fixing, or is it too much and better to sell it and look for a newer bike that hasn't been sitting. Not many small affordable sport bikes around here, some Duke 390s asking $3-4k next closest, but only a few years old. Oil was changed around 2k miles, darker brown but no metal in it around drain plug or on oil screen (only a couple very small grey plastic looking pieces on screen), changed filter, put in Castrol 10W40 motorcycle synthetic. -Was dropped on right side in garage supposedly, paint is pretty clean, slightly cracked fairing, couple sizeable dents in tank both right and left side, right signal taped on. -Handlebars need to be held slightly left to track straight, riding while releasing them bars wobble. Spinning tire with wheel up in air seems to wobble, wheel spins but not very free, feels like slight resistance slowing it back down. -Still on original tires from '04, have chicken strips on them still, rear has some cracks in sidewall. -Petcock seems to leak from drain hose, hose is plugged with a bolt. Fuel filter is incorrectly sized aftermarket, fuel line to it is kinked, carb float drain screw is stripped on one side, other areas missing some bolts. -Problems holding cold idle, seems to die unless holding throttle open manually, though carbs look new, some rust near top of fuel tank lid. Had bad gas in it, came out brownish orange color, though after warming up, idled stable, rode ok, revved well, engine sounds and feels good. -Starter motor seems to be bad, after a dozen starts where it seemed to crank fine, stopped cranking, solenoid clicks, except sometimes banging on the starter lets it crank. -Clutch makes knock sound at cold idle, engagement feels soft, doesn't grab hard on dropping it, engagement zone very wide. -Brakes feel soft, probably untouched. -Throttle has too much play, seems no adjustment left to tighten, cable looks new, maybe incorrect too long throttle cable was used, appears open/uncovered, missing a cover/guide. |

I think you're describing a bent front wheel, but I can't tell for sure. But a bent wheel won't cause the bar to pull to one side while riding. That's caused by misalignment of parts that support the wheel. If parts are needed, there are sources like partzilla.com, and you can check prices there.
You can get a petcock rebuild kit, or talk to Ducatiman, who rebuilds them reasonably. Put a voltmeter's probes directly on the battery terminals while cranking or trying to crank, and read the voltage. That will tell you if the battery is the problem. The clutch is adjusted externally. You need a copy of the shop manual. In the meantime, the How-To pages should help. https://faq.ninja250.org/wiki/Ninja250_Howto |

If I get a replacement petcock, is the diaphragm and the gasket part of it? What other parts should I get with it to try to replace it?

Yes, it's all one assembly. If you talk to @ducatiman about getting one of his rebuilt petcocks, I'm sure he can tell you anything you need to know about its installation.

1. If there was some rust near the neck of gas tank, does tank need to be de-rusted and coated?
2. Will this kit definitely allow me to restore leaking/failed petcock, or is it possible other parts of the petcock failed also and still won't work? https://www.ebay.com/itm/31273403228...3ABFBMgvSjv6xj 3. Why don't some of the petcock repair kits show this o-ring part? (pic attached) 4. Throttle cable seems incorrectly long size/missing a cover, will this replace it all? https://www.ebay.com/itm/25638087519...Bk9SR77Hq96rYw 5. Is there any difference in a motionpro vinyl throttle cable? Current list of known repairs needed, will have to pick up some tools, parts, gear. 1. Starter (ordered used. Can anyone share photo of how positive power cable connects to starter on their bike?). 2. Gas tank de-rust, clean, maybe coat (not sure if needed, but live in hot wet humid place. Current tank has a couple big dents, and a tiny rust spot on outside too, should it be replaced? Would then need to paint replacement tank too. 3. Petcock, fuel filter, hoses. (What kind do I need for fuel hoses?). 4. Throttle cable. (looking for used) 5. New spark plugs. (which ones do I want?) 6. Valve adjustment. (need OEM valve adjustment tool?) 7. Carb cleaning (can I do it myself if never worked on carbs, but done basic mechanical work before? Does it make sense to do any mods to these at this time to save future cost/work if planning to eventually do power mods?) 8. Chain clean, lube. Free play seemed close to spec. (What kind of lube?) 9. Clutch cable adjustment, possibly new springs (feels soft). 10. Tires 11. Front end and bars alignment, check forks for straightness, change to stiffer fork spring. 12. Weak/soft brakes service, check/clean/lube pistons, change pads, lines, flush/bleed fluid. If can get all of this done with affordable used parts, and do most of it myself, hoping can get it running safe, well, and reliable for a reasonable cost. Does it make sense to do any upgrades now while completing the above work, to avoid buying things won't need later and doing extra work now and again later to change them? |

I didn't use any special tool when I adjusted the valves on my '05. @ducatiman can advise about carbs and petcock. I recommend sending your carbs to him for a full, like-new restoration. If you want to do it yourself, this might help: https://n4mwd.blogspot.com/2013/10/s...-passages.html |

the gasket pic you posted is one from a "new-gen" (08 and upward) 92055-112
your petcock may have been changed with an updated, later model one? Please confirm otherwise a 92055-003 "pre-gen" o-ring would be correct. i stock all the required parts to rebuild either gen petcock.

The petcock seems to be the original pregen, it has OFF, ON, and reserve positions, which don't currently seem to work correctly, with the leaking.
Should this petcock kit contain everything needed to restore it, or is it possible a new petcock may be needed? https://www.ebay.com/itm/31273403228...3ABFBMgvSjv6xj Is there a recommended carb rebuild kit also, would this work? https://www.ebay.com/itm/30529966615...Bk9SR4rlnvqsYw I'm hoping to try doing DIY first, maybe with help from a mechanic friend to minimize paying labor costs on top of parts. Any tips/suggestions/critical parts/to do's appreciated! Does it make sense to do any upgrades now while completing all the above work, to avoid buying things won't need later and doing extra work again later to change them? |

in which case, your posted gasket pic is incorrect, not needed, actually supplied in your posted kit which should be correct.

Is there both a pull cable and push throttle cable on the '05, and need both, or one?
Is a used OEM replacement fine? What difference is there in a motionpro vinyl throttle cable? |
