January thaw?

Postby BPHORSEGUY » Sat Jan 21, 2017 5:56 pm

Todays temp hit 54 degrees and it had rained for almost 2 days prior so I figured all the salt was gone. I was right, no salt just a little sand on the side of some roads and in a few corners, easily avoided! I hit some of my favorite twisties. The ride was sorely needed as I was getting cabin fever or Spring fever. I was so into the ride that I didn't even notice the chillier temp near the end of the ride.

The Norton performed perfectly in the cool, dry air, it felt so great to get out! Near the end of the ride I thought I noticed the oil lite flash on for a brief second at a stop and sure enough at the next lite which was on a hill I saw the light again! When I checked the oil level I found it near the bottom of the stick, but near the lower line? I added about 100 ml of oil which brought it slightly over the top line and then went for a 5 mile ride with no lite! I checked my records and realized I had not checked the oil for almost 1100 miles, shame on me, won't happen again!

You must have a longer dipstick as I have. Never saw the oil lamp and mostly ride with oil level near the bottom end of the stick...

I will measure it. I remember there was a whole thread on dipsticks a year or so ago!

Does the oil light indicate low oil level, or low oil pressure?

I have never seen one indicate level as that would be all over the place with acceleration and deceleration, corners etc. So I'm going to go with pressure.

Simon, When my bike is stone cold it takes several seconds for the lite to go off after engine start , but it goes off instantly on warm or hot starts. I have always considered this as characteristic of a dry sump engine? How about others does yours do this?

I think its less of a temperature thing and more to do with the time the bike has been stood. For example if the bike has been stood for a long enough period of time for it to be cold then it has had enough time for the oil to drain down therefore to build oil pressure back up in the system takes a few seconds of the oil pump scavenging and priming. This is not a fault or a problem.

Simon, I think we are saying the same thing but you are saying it better or more completely!

Thank you

Doesn't oil like anything else expand when heat is applied thus creating greater pressure when warmed up? I get the occasion millisecond flicker of that and the fuel light. I just learned to live with it. It would take the dealership forever to figure it out. Took the bike out in some dense fog the other day, temps. high 40's. Aside from the digital display still stuck on trip, my head and tail lights were fluctuating from dim to bright to off for part of my ride. Short or varying voltage?

Oil pressure is created by the oil pump not heat. As to your lites it could be the voltage regulator or a bad connection or something got wet.
The cages don't see us in good visibility what made you go out in fog?????

Curtis,
Intermittent issues with instrument display, taillight and headlights all together, that would seem like a loose connector.
The boys at GC have had your bike apart a few times.
I wonder if they failed to properly seat a connector after your last visit.

Could be the main fuse which got loose. This one sits under the tank and should be zip-tied.
