Seafoam motor treatment. Has anyone used this?

[tclayton9]

No problem there is nothing wrong with questions. The slides are black you will see them when you take the air box off. Just take your finger and gently push back. Pour your seafoam in and that's all there is to it. When you see white somke once you run the bike don't be alarmed its normal.

Alright I thought so, thanks so much. So when the white smoke is coming out do I just let it I'dle till the smoke stops? Or do I need to ride it a certain distance or something

[tclayton9]

Ride it and then add more gas to the tank and then your done.

[Acd92910]

Okay I did that and I'm waiting now. Thanks for the advice. I accidentally poured some of it on the slides is that GOJNG to damage them?

[tclayton9]

no not at all.

[Acd92910]

I let it sit for about half an hour then turned it on and then took it out. My problem was the bike not being able to start without the choke engaged so I'm going to see if it can cold start tomorrow without the choke. I don't think it really did much judging by what u saw today, Maybe I didn't put Ebough?

Get yourself, a buddy & 4 small cups/containers. Pour about a 1/2 ounce to an ounce of Seafoam in each cup. Warm up your engine to normal operating temperature then let it idle. At the same time you & your buddy take two cups each & try to pour the contents into all four carbs at the same time until the engine chokes & dies. Let the engine sit & soak for 15-30 minutes or longer, then start it up & run the rest of the Seafoam out of the engine. You will most likely have to hold the throttle open & run the engine at a fairly fast speed until all the white smoke clears up. Once the smoke clears up, you might want to change your sparkplugs & crankcase oil.

let us know how it goes. is the bike having problems starting with the choke off or running with the choke off. I had both problems on my 93 fzr.

[Acd92910]

It's having problems starting with the choke off. But once i run it and it warms up it idles okay

[tclayton9]

Sounds like your starter jets are clogged. My jets were dirty as crap when I went through my carbs. Mine would start with the choke on and off but wouldn't idle with the choke off and it had a horrible throttle response.

[Acd92910]

Could that also be why it sometimes won't accelerate no matter how much has I try and I've it at about 5500 rpm in 4th gear?

[tclayton9]

Exactly. Normally if a bike sits along time before being driven the carbs will need to be cleaned. The job is not hard and can be done by yourself with ease. A shop will charge you half of what the bike is worth. I was quoted 600 dollars with the carbs in the bike and 200 dollars with them being out.

[Acd92910]

I tried the seafoam method given on here with no luck, I'm guessing that my jets and carbs are gummed up and dirty to the point that nothing short of a thorough cleaning will work.

Time for a carb break down.

Pouring Seafoam down the carb throats doesn't do anything for the carbs, at best it will loosen up some carbon in the combustion chamber that's not causing any trouble any ways. The majority will slide down past the rings while you give it it's 30 minute working time, pulling some oil off the cylinder walls that you want there, to make it's way to your sump and oil. Watch your oil condition as noted by Seafoam as you've just shortened it's usable life, it will soon be loaded up with gunk the solvent loosens up in your bottom end.

For it to do anything for your idle, it needs to be in the bowls in a strong enough concentration that the bike won't actually run. Added to your gas in a concentration that the bike will still run with, it'll take multiple tanks worth of run time to have a noticeable impact. If your pilot circuit is completely plugged not even Seafoam in the gas will save you as there won't be any vacuum to draw it into said passage to work on the blockage. Save some time and frustration and pull the carbs for a proper cleaning. (Also, why is it a problem if a carb'd bike doesn't want to start without the choke when cold? That's normal and anticipated. If it needs choke to idle/run once it's got heat in it, you've got a problem. If it doesn't need choke to start when cold, your pilots are too big and you're running way fat at idle.)

I'd use Seafoam for what it's good at, as a pre oil change treatment to the bottom end, but only if you've got signs that you've got appreciable build up. If you're doing oil changes regularly with decent oil there shouldn't BE buildup.
