Carb cleaning QUESTION
Whats up everyone,
So I just got done removing the carbs off my '08 250 for the first time and I gotta say i feel pretty damn good, mostly because i've been putting it off for nearly a year and its finally done. My bike was all sorts of sluggish the last time i rode it. After messing with the fuel treatments, changing spark plugs and air filters, i came to the conclusion that something was wrong with the carbs. Long story short, I expected the carbs to be very dirty but when i opened the float bowls, everything was CLEAN. No gunk, no residue, just a lot of fuel. I figured I might as well clean what i can on the carbs while they're removed. They have been pre-soaked and scrubbed in a pine-sol solution. Everything looks great so I'm not going to follow through with a carb cleaner since it looks unnecessary and i don't want to disassemble any further to remove any plastic parts. MY QUESTION IS, after I rinse off the pine-sol solution, is it good to air dry and reinstall or is letting water dry on the carbs a bad idea? How do i go from pre-soak to reinstalling back on the bike??? |

Have you remove the both main and pilot jets? Main jet holders? Did you remove the slides? Idle needle screws?
To answer you original question, you need to blow out the carburetors, and all the fuel circuits, as well.

Another thing to check is the OEM fuel filter located just inside the fuel inlet elbow, might be clogged.
Also are there any modifications to the bike at all? When you say sluggish, at what point or points?

I have removed the main and pilot jets, main jet holders, the slides and the idle mix screws. The reason I ask is because I rinsed it with water and noticed corrosion forming almost immediately after drying. Can't be good.

Hit them again with carburetor cleaner, and then blow them out, and all the circuits as well.

Just checked the fuel filter,very clean, nothing clogging it up. there are no modifications besides a K&N air filter if that counts. Laggy I think is a better word now, not sluggish. Anytime I accelarated, it felt like it took the bike a second to realize that I turned on the throttle, making it go. Maybe 1-2 second delay. Just a poor response.

That's the idle mixture screws need adjustment, here is my how-to write-up
Quote:
Also here's another how-to on syncing carburetors the proper way. Quote:
It's also important to keep in mind, to get it running smoothly, before doing any shimming, jet changes, etc..... Let's first get a solid baseline to start with. Hope this helps, any questions, just ask.

Also if you parts, etc... Send @ducatiman a PM, he's from the EX-500.COM but he also lurks he as well.
He offers carburetor services and I personally vouch for him.

I'm a little late to this but I almost always replace pilot jets. The tiny hole gets blocked because of corrosion. You need a proper jet reamer to open it up to the proper size not just open.

guitar string .011", .012", .013" or larger (depending on jet size) works perfect
