2009 Rebel 250. It's my MIL's, who decided she didn't like riding. She wants me to sell it. I'm in California so I assume it's a California bike.
It sat for at least 5 years. She has a receipt showing an oil change in 2012.
It wouldn't start.
New battery. Still wouldn't start. Sprayed some starting fluid and it ran for a few seconds.
Pulled gas tank and drained - super clean inside.
I had FIL pull the carb and bring it to me. Valve was completely stuck, carb had no gas, not even the smell of gas. I replaced the valve and soaked the metal parts for about 30 min in SeaFoam (it's all I had).
FIL put the carb back in, it started. They drove it to my house (about 20 miles), the 2 side covers were COATED in oil. The fins had an oil film and they were smoking when the engine was hot.
They reported that you had to give it a lot of gas when starting off in 1st gear or it would die.
I test drove it, came home, let it cool down, the right-side spark plug was completely loose, so I torqued the spark plugs to spec.
I fired it up again so I could try adjusting the idle speed screw, and a few minutes later, before it came up to temp, it puked oil out the left side.
Got the bike vertical and checked the oil level - it was at the very top of the XXXX part. I checked with the bike vertical/level and the dipstick not screwed in. This level was AFTER it leaked oil on the drive over and AFTER it puked from the blown seal. I have a feeling it was overfilled. All parties deny any knowledge of overfilling.
I ordered a gasket kit, the pulley removal tool/screw thing, and a new seal.
Today, I opened it up and replaced the seal (it was chewed to hell). Put her back together and let her warm up to idle. I played with the idle screw but it didn't fix the problem. The pilot screw is missing the cap so I can't twist it to adjust that. I ordered a new pilot screw, which comes with the cap, from Revzilla. Should be here in a week or so.
FIRST PROBLEM: You're in first gear and ready to go. You apply a little throttle and she starts to struggle and will die if you don't: 1.)get off the throttle, or 2.)rev it like hell. This is without messing with the clutch. I've been riding for 8 years now, I know how to feather the clutch!
SECOND PROBLEM: I can't find the oil leak. There's oil pooling at the front and left fins near the spark plugs. But that's because the engine is tilted and the bike is on the stand. I suspect the valve cover gasket, but I wiped everything down and let it idle for about 40 minutes and didn't see anything building up. It's a head scratcher. I have the gasket kit, so I can replace it, but I'm reluctant to do anything unnecessary. Bikes that sit 5 years have a lot of dried out rubber.
THIRD PROBLEM: that same right-side spark plug appears to be blowing out exhaust. Or maybe it's leaking oil near there and that's the smoke? Anyway, the smoke appears to be concentrated in that area. It's been windy so it's hard to tell. I let it cool down again and re-checked the torque, and it's perfect.
Any thoughts/ideas? What to do next?
My thoughts are to pull the carb again and soak it in a carb cleaner overnight, then pull the valve cover (do the valve job since I have the offset wrench and the feeler gages) and replace the gasket. When I get the pilot screw cover, adjust the idle to see if that helps the stalling when you give it a little gas.
