I run some Seafoam every now and then during the riding season because it absorbs moisture and isn't harmful like isopropyl alcohol.

i did not know isopropyl was harmful,what damage does it cause to the RX-1?

Its hard on rubber parts, floats, fuel pumps. It dries stuff out. Its best not to use isopropyl being an additive like Seafoam is available.

I've heard that it's not good to do an off-season start because you can never get the engine warm enough with no load. Because the engine is not running under the conditions it was designed to, lots of unburned gasoline dumps into the crankcase and mixes with the engine oil, which is bad for the crank/bearings. Also, I have heard from many that premium fuel, with it's higher alcohol content, draws moisture into the fuel system during storage causing rust, corrision.

True for all of the above, but don't run premium because there is no benefit of using it.
I dont know about you guys but when mine sits and runs for 20 min it gets plenty hot enough. A new film of oil is placed all over the parts again and any part with oil all over it is not going to rust. That is why I start mine once a month. I do top off with premium for storage but run regular all winter.

Sled Dog, if you fog the engine when you store it, the engine parts will have the coating of oil on it til you start it next season.
Fogging only does the cylinder and valve heads

I can't wait once a month so I put in a fresh 1/4 gallon every 2 weeks and fire it up once a week till it gets good and warm.

I agree with Sled Dog about leaving the treated fuel in the system. If you don't treat it and think draining the system is the answer, you can never get ALL of the fuel out. No doubt, the fuel left in the system, combined with abundant oxygen, will leave you some nice gum at start up time in December. Draining treated fuel only allows room for moisture and oxygen to work together to do their nasty deeds on carburetors. I think it's best to treat fresh fuel, run it through the system and leave it. Just my opinion, though.
As for running it, yes I am sure it will get hot, but only because there's basically no cooling. Perhaps I am wrong (typically), but the fuel will not burn cleanly in a engine that is not under the load it was designed to operate, no matter what temperature the coolant reaches. Thus, the unburned fuel mixes with the oil...yadda...yadda....yadda...
Maybe this isn't a big deal with a dry sump??? At least the unburned fuel and oil mixture isn't sitting in a pan along with the crank and bearings.

If at all possible you should be using Sea Foam. I have posted to similar threads with my experience using this product. It goes in EVERY motorized device I own. Regular use in my 95' Eagle Vision TSI has eliminated injector cleaning. ALL my lawn care products are treated with this product with every purchase of fuel. NEVER had a single issue when starting after storage. Just started my Lawnboy mower for the year. Primed it and ,WWAAHHHH, first pull. My 91 Phazer sat in storage for 2 full seasons. Pulled it out for a backup for my last ride. Second pull, WWWAAHH, never even fouled a plug. This product stabilizes, cleans and conditions your fuel. Sorry to be longwinded, but I have seen MANY small engines with Stabil that still need a thorough carb cleaning after storage.
USE IT,YOU WILL NEVER USE ANYTHING ELSE!!

I just leave mine sit all summer. What could go wrong? Nothing.

Storage and draining the gas
I don't know how long the season is in your areas of the country / continent, but here in the Midwest we have 2 1/2 months or riding and the rest of the time these machines sit in garages, on trailers, barns, warehouses and moisture is the enemy. I have stored motorized vehicles for years and have seen the damage done when not properly winterized or summerized. If you've ever noticed the rotors on your car after a rain they will rust in hours. The interior of your engine (cylinder walls) is no different except it's invisible unless you tear your motor open before starting. Four strokes are more vulnerable to interior corrosion than 2 strokes since there's not a coating of oil throughout the upper part of the motor. The old premix machines were nearly impervious to internal corrosion and the carbs nearly ever showed oxidation. I take the following steps, drain the fuel tank, run the machine until it dies, drain the float bowels, fog the engine after the engine has stalled and continue to with the electric starter so the oil gets into the engine. I also squirt a little fogging oil into the fuel pumps to keep the diaphragms moist. Finally, change the oil, clean the machine, loosen the track, remove the battery and that's it. Also, with all the TY talk about lubing the suspension I pulled the skid, replaced bushings, greased, and reassembled. My sled cost me 9,500 with Ohlins and some added junk and I look forward to it being as fresh as it was when I put her to bed in March 05.

Sea foam is a great product since it is not alcohol based like sta-bil
However seafoam does nothing for the volitility (spelling) or the octane of the fuel. :shock:
Old stale fuel will kill a 2smoke. I do not think it will do any good for the 4 stroke.
Old fuel is harder to ignite in cold temps. Thats why your snowthrowers will not start on year old gas but your lawn mower will. If the fuel is low on octane it will detonate before the s/p tells it to. Old fuel will leave nasty deposits as it burns. Try running your string trimmer on old fuel and watch the s/p foul.
Any way enough said. I prefer to drain the fuel system and carbs and fog the engine
Just my 2 cents
