What is this Green crap? Algae in my 2004 CRF250x carb?

Recommended Posts

Well I am guessing this why my bike isn't running really well with up and down idling, running really lean and hot? What is the best stuff to clean and or soak this in?? - Thanks

brass turns green when it corrodes, your jets are brass

that carb is so bad I would replace all the jets

Looks like ethanol got you. Ethanol attracts moisture, it's a huge problem in all my vehicles that sit for more than a few days. Fuel stabilizers help, but it still happens. I had to replace two aluminum gas tanks in my boat from internal corrosion because of this, those tanks were $600 each!

@MegaDeTH - I'd have to agree, i cleaned them up pretty good, but I am thinking its worth a new kit with jets. Also I think i F'd up, i am guessing carb cleaner wasn't meant for the throttle value and rollers area up top, the carb cleaner must of dried it up and now its sticking. My pilot jet was plugged for sure, couldn't push anything through, had a thin wire to poke it through.

Man I'm glad I live in Missouri where we have better air and our vehicles don't mess up only after ethanol sits in the tanks for a few days!

Hell e85 users would be screwed :cheers:

yeah your not supposed to put carb cleaner on plastic/rubber bits, it can ruin them, or remove a coating when they have them. I've heard of people using pinesol + water to soak their carb parts in and supposedly works great, I've never tried it though..
