isn't the straight 50wt too thick for colder climates? I see you are in Canada.I'm running Lucas straight 50wt oil in my engine. I just ordered a case of 50wt synthetic.
I'm running a 124" and when it does get hot in the summer my oil light comes on at idle. I'm also running an oil cooler. Only have trouble after driving around for about an hour in stop and go traffic. No problems on the highway. I always warm the bike up real good before i ride. Once it gets colder a don't ride.isn't the straight 50wt too thick for colder climates? I see you are in Canada.
