Start Up After 5 Month Winter Storage- Advice Please

For that amount of time I wouldn't bother. I wouldn't change the oil again either, you'll be changing new oil for new oil. Just make sure that battery is fully charged and strong so it turns over easily.
My ZZR was laid up at the end of November and I'll be waking it up around May time with the same procedure

 

What he says.

 

Yes if it is in a cold garage with condensation then it won't hurt to throw some new oil in the engine. Cylinders I don't think it warrants that. Alought when I store my bike I add a capful of two stroke mainly for the old e5 rubbish petrol then o start up I top up the tank and just let start on tick over for a few minutes

 

Provided you haven't started and run the engine while in storage, there will be negligible condensation in the oil IMO. Just using a bike on short commuter runs can emulsify the oil due to condensation so starting and idling the engine when stored is a big no no in my book.
As I've said, I wouldn't bother changing it again but If another change gives you peace of mind then it's worth it for you.

 

Hi Kenzo.

I feel your pain when its comes to un necessary worry... I'm th same and get worse with age....

BUT... Iv stored my bikes/stationary engines/cars and lawn mowers up to minus 14 for 6 months or more every year without any problems.

I do th same as you.

"In late November I put my bike up for winter in my unheated garage. I did a final ride, replaced the engine oil and filter, cleaned the bike and sprayed with anti-corrosion, added stabilizer and filled the tank with fresh premium gas, cleaned and lubed the chain and put it up on front and rear stands"

Except i put my tyres on insulation board to seal it from th cold floors.

My bikes and all other engines start first time once th fuel gets there. I put that down to th fuel stabilizer (spark aider). Iv never put oil down th bores ever. You wouldn't want hydraulic lock if to much went in there....

Please dont change your oil as a more or less sealed metal box (Your engine) had very little or no damp in side it after your hot drain down last November. Starting th engine for me in this period only puts moisture in as others have said..

Remember kids that a gallon petrol burnt in a internal combustion engine produces a gallon of water. So if this gets in th crank by "Blow by" (some of th gases pass th pistons/rings) and then it goes into th sump... On all vehicles it does this but I was told if th oil gets to around 74c and above it then boils off all this water and emulsification dosnt happen as much if ever.

For me my conclusion.

Old wives tails about bore lubing dosn't exist th same on modern engines than as it did in th past.
Oil in water only happens if you start a engine and it never gets to proper oil temperature (74c and above)... In brand new oil there would be very very little water in it, if any.

If you want to be really safe which we do with classic cars some times after not been started for years, is move it around in a high gear to see if th engine turns. If it does and it will, Then give it a wizz over with a full battery with kill switch on. This puts oil every were it should be without starting th engine.. Then turn kill swith off and start it and leave it to idle for a min or too then gently drive it away.... On any engine iv had i always nurse it up to temp. Most engine damage occours when its cold. This is why short journey stop start driving kills engines quicker.... (One lady owner shopping trolly comes to mind)

Good luck and let me do th worrying not you...

 

If I was concerned enough to oil the bores prior to storage I'd use misting oil instead of removing the plugs and pouring engine oil in. I used misting oil when I had the boat and laid up the outboard motor for Winter.
Remove the plug leads or disable the ignition, then crank the engine over while spraying the oil into the carbs/throttle bodies for a few seconds.
