We know 90% of wear occurs due to cold startup ,I'm wondering if something like this couldn't be adapted for use on our bikes.www.Wolverineheater .com/model4-5/4.5.htm WE should be able to place it on the bottom of the case ,near the oil drain plug (haven't looked) and run the cord aft and up to a frame mounted plug socket ,( like you might use to hook up trailer lights?)so the cord could be removed just before startup?

If we aren't in an Arctic Zone......I don't believe the cold temperature that causes the wear in a "cold" start. It is the lack of oil pressure and the lack of an thick oil coating on the bearings/piston/cylinder/cam/rockers. (Although I will concede that the folks that ride in very cold weather likely have some pretty thick oil to get flowing - but some of us just don't feel the need to go riding when the temperature drops below 50!)

When you shut off a hot engine the oil is thin and fluid, and most of the oil flows off the engine parts and drains to the sump - and what is left behind is a very thin oil film. The Savage engine has roller and ball bearings, and those can get by with very little oil at the cold start. The piston/cylinder/rings and cam/rockers are likely where the most wear occurs during startup in the Savage engine.

I don't ride in sub-zero....so I don't see any need for an oil heater.

Reply #5 - 07/13/17 at 12:36:03 Interesting idea, but I would think it would be easier to switch to a 5W-40 oil and add redline if needed. Personally, I find it starts fine down to the mid 40s, at which point I can't find gloves thin enough to operate the controls and still keep my hands warm.

I don't believe pressure is the problem,the fact that cold oil doesn't flow as readily as warm oil is.the reason we drive the bike without going to wide open throttle for the first few miles after a cold start isn't because we don't have pressure but to give the oil a chance to warm because that provides better flow and a thicker film between the parts. it would seem to me that warm oil would provide more lubrication ,sooner ,to both the valve train and the piston /rings /cylinder walls ,or am I crazy ?Running one of these heaters on a lamp timer to turn on 8 hours before your intend start would cost less than4 cents a day /14.00 a year .the closer to running temp (about 270) the faster it warms and the less wear .(no I don't own stock in the company

)

Through the magic of modern science and viscosity improvers, oils with a low winter weight, like 5W-40 flow thinner when cold. http://www.belray.com/what-exactly-do-multi-visc-designations-mean
The two things that contribute to cold start wear are the milliseconds that there is no pressure in the bearings (like the cam) and the few minutes it takes for the metal to expand and clearances to come into spec. Anyone who has listened to a diesel started in sub zero temps can relate. As for how much that heater would bring up the temp. of the whole engine? Undecided

All I can say is the product comes from a company that gives it a two year warranty, a mounting kit ,online instructions for mounting and is sized to heat 1.9 liters of oil . Our bike holds 2.4 with a filter change,1.8 without, so I assume the case holds in the area of 1.8 at rest.I donit know if anyone needs/wants one but I thought members should be aware that they exist.( anyone running a snowmobile?)

I've had three times when my bike wouldn't start. Normally runs and starts great, but not when below 40. I'm in South Carolina. Years ago, I used to use a small space heater under my bike about an hour or two before startup in the morning. Worked great back then!

Put on a pair of neoprene shop gloves under your motorcycle gloves. Adds 5 degrees or so to the bottom end of your comfort zone, and has no meaningful impact on hand mobility. Also has the added benefit of making non-waterproof gloves functionally waterproof - the gloves will get wet, but your hands won't.
