The seafoam works best if in the oil and gas as LB has said. I put two cans into my diesel which had lost power was using oil, idled rough and fuel consumption increased to the point I was only getting about 10 miles to the gallon. I put one can into a half full tank and put a whole can into the oil also. Drove it hard while the seafoam was into the fuel and drove it another 2000 klics with it in the oil. Noticed improvement in fuel milage gradually and the idle improved after the first run. Changed the oil after 1500 to 2000 klics on it and now it has improved the fuel mileage where it was before about 18 to 20 mpg the idle smoothed right out and it has not used any oil since before the oil change. I used some in my gas on the Royal Star Venture and it actually kicked out some black soot from the tail pipes. I would not hesitate to put some in the oil in my RX-1 especially with only a couple hundred miles to go before an oil change. I will also be using this for summer storage as well. Now I have not had any oil burning issue I use some but very little. I use amsoil 4 stroke oil and I run the Fitch Fuel Catalyst also. So maybe the fitch is letting the fuel burn cleaner thus preventing the carbon buildup at all. I wonder how many people who run the fitch are having or have not any oil burning issues.

I was useing oil in 1 of my RX1s and tryed the seafoam. Now 700 mile later and no useage. I say useage cause I feel its not blowby. Now I use it in everything that burns gas. I'm a beliver

I have been slipping a bit of the seafoam fule additive into my wife's drinks. She seems to be performing much better. Less chatter, less complaining and gets more work done. I'd say this stuff cures everything that starts running bad.

Got to be cafefull feeding that stuff to humans. If she's a talker, you get a real motormouth & if they get on the wrong subject (e.g. Not buying that new toy next year) you reallly got problems.

Reading the side of the can (skull and crossbones) feeding it to the wife would probably make her really quiete...
Last night I installed a set of stock CR9E plugs and poured 1 pint (478 ml) of Sea Foam into the gas. The CR10EK's that were in the sled looked a perfect tan color (no signs of burning oil). I rocked the sled a little to mix it up and filled the tank to the brim with regular.
The oil was topped right to the full mark at the end of the last ride, but I checked the oil to look at the color (nice and clean looking).
I then went for a 250 kms ride. At first everything was normal with the rpms peaking just under 10,000 rpm at WOT (same as last ride). I could smell the Sea Foam being burnt, but other than that everything seemed normal.
After about 125 kms I noticed the WOT rpms were running around 10,250. This could have been because of the -20°C temperatures. Towards the end of the ride I noticed the sled seemed to be accelerating better than ever. The rpms were now 10,450 at mid speed (80 kph/50 mph) and about 10,350 everywhere else. Again could be the cold...(or maybe the belt is going?). One other long shot I can think of is the exhaust leak (that is getting worse) is possibly increasing the power??
I did all 250 kms (156 miles) on the same tank of gas. The fuel light just turned on a few kms from home (probably could have done another 40 kms).
When I got home I checked the oil after idling for 1 minute and found it was down 250 ml or 1/4 of a quart (took 250 ml to bring it to full). I was surprized to find the oil was still clean.
I guess the next few tanks of gas will tell the story.
If this doesn't fix it I'll try a little Sea Foam in the oil next time.

I put Seafoam into my 03
I just got back from 1900kms and checked my oil since last oil change I have almost 3000kms and I added 1/4 of a litre to bring it back up to full.
When I used Seafom at the start of the season I used a ink jet sringe and put 10cc down each sparkplug than turned motor over by hand than I put the plugs back in with out the coils attached than cranked the motor over for 5 seconds.
ENGINE MUST BE HOT to do this.
let it sit for 5 minutes and than restart in a well ventialted area. The first time I did this I thought the sled would never quit smoking. It took almost 10 minutes for it to fine run clean.
This has also been done on my friends 04 and same results oil consumption is almost nil.

Well sea foam help me out alot, but i just did the Ring free and now my oil useage looks to be GONE!!!

I put 700 kms on the sled yesterday and it burnt 400 ml (almost 1/2 a quart) of oil.
The Sea Foam in the gas doesn't look like it helped. If it helped, it helped very little.
I'm going to try the Sea Foam in the cylinders to see if it works.
I also tried to buy the actual Yamaha Ring Free, but apparently it's not available in Canada.

REX,
By my math you made some pretty good progress!!
1.1 ml per KM in your first post. [ 600ml in 544 km]
.57 ml per km in your last post. [ 400ml in 700km]
Hope it keeps improving for you.

True, but what I didn't tell you was when it burnt 600 ml in 544 kms, about 90 kms of that was with me breaking a trail in 2-3 feet of powder running close to WOT almost the entire time.
My guess is it burnt more oil because of the sustained high rpms.

Something to keep in mind. Using seafoam or ringfree is just a band-aid to the real problem, weak rings. Thats why Yamaha's fix is to use the newer ('05+) rings. They have more tension. I'm not saying that using seafoam won't work, and its sure a lot cheaper and easier than replacing the rings if you have good results, just don't expect it to work miracles in all cases. I also don't like the idea of using it in the crankcase. First, it won't help the problem we are having, which as to do with weak rings and the top ring getting gunked up. The crankcase oil doesn't even get up on top of the rings (otherwise you'd REALLY be using oil), so it won't help our particular problem. Second, if you have been running clean motor oil (changing it on a regular basis), you shouldn't need anything to "clean" your engine. And as an engine builder, I really hate the thought of adding other things to the oil. I have read many studies and tests of "engine treatments", and they basically fall into 2 groups- the first, and the one that at least won't hurt the engine, are nothing more than standard motor oil being sold for $10-$30 a bottle. The second group is basically mineral oil with some scary additives, such as Teflon. Teflon might sound good, and looks good on the bottles, but even Dupont doesn't suggest using it in motor oil because the particles are too large, and can actually cause engine damage, and can, in some extreme cases, clog oil filters.
With that said, I can't see any way that seafoam could harm anything by using it in the gas or soaking the cylinders. Thats why I tried it. I knew my problem was really severe, but I was willing to try just about anything at that point.

Jim, my sled is an 05.
I agree with you 100% on the additives. I'm going to try the cylinder soak method probably this evening. I might try not adding any to the gas and see if the soak alone is the ticket.
BTW, my sled has run 0w30 Yamaha oil since new and the oil has been changed more frequently than required. Also the filter was changed with every oil change. On top of that evey time it is started it's typically kept at operating temperatures for 10+ hours at a time and it's always run hard enough I wouldn't expect much carbon build up. I don't understand why it's burning oil.

I also wondered why this problem is happening. I'm surprised its happening to your '05. I also ride long days, and hard enough that it should stay cleaned out. I broke it in well and changed my oil much more frequently than required, and changed my filter at almost every oil change just to be safe. The other thing that was mentioned by a Yamaha rep is that the ring issue could be caused by the types of gas we get in some parts of the country. Apparently the blends we get could be causing the buildup on the rings. I wish I could have pulled my engine apart myself so I could have seen what it looked like.
