Season is over in MN, any summerizing tips for Nytro?

[Skeeterzx225]

So it's supposed to be in the 50's this week, Trails will be toast by the weekend. Are there any Nytro specific summerizing tips you can give me? This will be my first offseason with a yamaha 4 stroke, what should I do to ensure everything is ready to go next fall?

I personally add a gas preservative like Stabil and then about once a month I let it run and let it warm up. So far it has worked for me with no issues for the last few years.

Change oil,grease and make sure its clean. Charge battery monthly...Add fresh gas before riding.

In addition to the above, time to add more MODS (--:

I'm not sure if mine ever really gets put away for summer. It seem like there's always something I need to or want to do to them. I'll be topping off the tanks and adding Marine Sta-Bil.

MARINE Formula STA-BIL Ethanol Treatment is a new, enhanced formula of STA-BIL, America's top selling fuel stabilizer, that was designed to fight many of the unique problems related to ethanol in gasoline in the moisture-laden marine environment, and fights those problems in three ways:

1. Fights Fuel System Deposits – Ethanol in gasoline acts as a solvent on the accumulated deposits in marine fuel tanks, fuel lines, carburetors, injectors. These loosened deposits can cause engine performance problems, including hard starting, rough running and stalling. MARINE Formula STA-BIL cleans-up power-robbing deposits from carburetors, fuel injectors and intake valves to improve engine performance. MARINE Formula STA-BIL contains more than FOUR TIMES the fuel system cleaner in Regular STA-BIL – it is a Complete Fuel System Cleaner.
2. Fights Fuel System Corrosion – Ethanol in gasoline attracts water from the moist marine air. Since virtually all marine fuel systems manufactured through 2007 vent to the air, the ethanol continually attracts water – which can cause corrosion damage to marine fuel tanks, fuel lines, carburetors and injectors. MARINE Formula STA-BIL contains DOUBLE the corrosion preventer in Regular STA-BIL, to fight the unique problems of ethanol in gasoline in the marine environment, including marine fuel tanks which vent to the marine air.
3. Fights Fuel Degradation – Pumped gasoline starts to degrade immediately. MARINE Formula STA-BIL keeps fuel fresh for up to 12 months in marine gas tanks. Just like Regular STA-BIL, adding MARINE Formula STA-BIL Keeps Fuel Fresh , and eliminates the need to drain fuel prior to storage.

X2 marine stabil. i run it all season long and for storage in my nytro and waverunner. per the manual, theses motors are only rated for 5% ethanol. pump gas is 10% here in New England.

I add stabilizer, and disconnect the battery for the summer.

The number one suggestion would be to move north so you can get a longer winter. I'd be on suicide watch if my winter was over already.

sea foam and battery tender.

I fog mine, even though everyone says it's a waste of time. The service manual says to fog it, and it's not that big a deal. I would fog my streetbike in the fall, if it was as easy to do as the sleds are. I've been using marine Sta-Bil for the past couple years with good results. I always pull the batteries out and keep them in my shop, and charge occaisionally. I get very good battery life doing this (5 years +). I don't change oil in the spring - just when I do the pre-season service in the fall.

 

[loudelectronics]

Seafoam. Put it in your tank, put a bit in your crank case, run it till it warms up. Change oil in fall and that is all I do. Keeps the water away. I do not change the oil in the spring because of water intrusion, hence the seafoam in the crank case.

I do also start it a few times a summer so the oil coats everything again. I have seen to many boats that sit for a few weeks get pretty rusty from sitting inside the motor. The oil film dissipates and rust will form.

 

[woodydog]

I Grease everything and put Seafoam in my gas tank, make sure it runs long enough to get through all the fuel lines and that's it. My Girlfriend has an 07 Phazer with only about 3,000 miles and my 09 Nytro has 4555 miles on it and have never had a problem. Have never even done anything with either battery, no tender, no unhooking from cables, nothing, and both crank like they are new and run flawlessly.

If the gas that is in your sled has Ethanol in it, get it out and put in some pure gasoline. Some of the Premium gas around here is still ethanol free.

Of course if you can't find pure gasoline without ethanol, you're kinda screwed so just do what they said above.

Added to everything already mentioned I also spray a layer of WD40 over all the metal...keeps it nice and shiny and keeps everything from corroding.

I use Rust Check, and coat everything metal on the sled, and of course grease everything that can be greased.

X2 on the Rust Check or something similar

For those that use WD-40 be careful with it as it can and will disolve grease, especially the real hard to see ones like your idler bearings

I also find WD evaporates and doesn't last near long enough to protect a sled or anything else for that matter for any extended period of time.

I mainly use Rust Check and Krown products but I know these can't be purchased in a lot of U.S. states, but there are other alternatives I am sure that would work just as well but will not disolve grease like WD does.
