It's an SV650...but carbs are carbs. The bike was left to sot for 8 years full of fuel. The guy isn't investing much money...a full tear down is out of his price range, though I'll probably do it anyway because I'm nice. All he's paid for is a dip and replacing the jets. I've had the carbs in naptha for 3 days now and, while the betterflies are a bit more loose, it's not as nice as it needs to be. What else can I try? I'm going to douse them in alcohol later, but I'm worried about soft parts. Carb cleaner isn't getting into the pivots very well and makes little difference.
Suggestions?
Probably have to tear them apart, anything that would be effective would probably damage gaskets and such.
Or you could just use the BFH . . . . .
I've never tried it...but have recently read about people using pine sol cut 50/50 with water and left to soak....drop them in as is ( a day or two..slosh occasionally...) rinse /blow them out well- and a normal going over after...
Does it work well..... dunno yet...may try an old set here if I get really bored.
8 Years.... It's not your fault it's not coming clean- tell him it needs a real tear down (and more money...being nice is ok but it doesn't pay many bills...ask me how I know :icon_mrgreen: )- or I've seen sv carb sets for 70-100$ on Fleabay...may still need going over tho too.
The slides move freely but the butterflies don't... soak them in diesel maybe... keep working them....marvel mystery oil maybe...
if the guy cant aford 80 bucks to get he carbs cleaned he should learn how to work on them himself. if your not doing a full tear down dont waste your time or what little money he does have on just soaking and replacing jets because its not going to make it a full day of riding before it doesnt run again would be my guess.
Ultrasonic cleaner?

haha I actually have access to one!
Josh...$80 doesn't cover a full tear down. You'll be hard pressed to find anyone who'd do a full tear down on SV carbs for less than $150.
I was gonna say Pinesol too. Someone posted before/after pictures on here once. They started with some gross old carbs, and pulled out what looked like some new carbs after soaking for 24 hours. I planned on doing it to mine eventually, just haven't gotten around to it yet. Mine work, and the bike runs well, but the choke won't work right and I've cleaned them by hand more times than I count so I figured it's worth a try.
I've heard the pine sol thing a thousand times, now. I'll probably try that tonight if I can find a tub that'll hold the carbs without needing 20 gallons.

How would he buy tires, gasoline, chain, cogs, and on and on......... Charge him a fair price or return the job to him.
prs
He paid for new tires, suspension service, and brake service. After investing that much in a $2000 bike, he's reluctant to spend $200 in parts and labor to to a full tear down on the carbs when working replacements can be bought for under $100. He's paid for a dip...there's no labor involved, thus cheap as sin. It's just a matter of finding which of the plethora of chemicals I have access to will work best.
If pinesol doesn't work, try hot water and dish washing liquid, and the next step could be water and baking soda. But remember, alkali (and all of these are alkaline) will clean the thing, but will also turn it black. That leaves it open to get oxidising ... white flour like dusting on the thing. Probably not enough to matter, but it would look dark and look funky.
Cool.

I'm going with a bigger hammer. :bs:
I take my carbs off and disassemble soak everything with out o-rings and gaskets in carb cleaner for a day then fire up the compressor and a brush and get the stuck stuff and blow everything out. then take and reassemble with a carb kit. I don't think I've hit a $100 doing it myself. Unless you count the time I re-jetted and replaced floats. I've taken carbs down and not changed gaskets and o-rings and done fine as well. but if they look bad they are and you need to replace. Honestly though once you take it apart you know where everything came from, and if you lay out your gaskets, o-rings, and springs in the order they were removed you can do it;and next time it'll be a breeze.

I've had carbs that I couldn't take apart cos the thing was gummed shut. Soaking in yamaha carb cleaner and hot water eventually got it clean and openable.
Cool.

Those must have sat for eons. :icon_lol:
You do what you gotta do to get em apart!
From 1991 to 2008. He had to leave town in a hurry he said.
Cool.

I had to deal with that with my old CX500...left to sit since 1984 til 2006. That was nice. I had access to a high temp hot dip back then...after two weeks the bowls finally let loose.

I didn't see the naptha part ... you really do not want to dip em for any length of time in any petroleum product except gasoline, even gas I dont like ... but diesel and kerosene will eat and melt the diaphragm, in fact they turn sticky and yucky.
Cool.
Buddha.
Naptha's actually pretty kind to neoprene/rubber products...but the diaphragms, caps, and slides weren't in the carbs.
