I mean I run my CG a bit lean, but with more oil. Never overheats. A bit more top speed, but be careful if you do that. Not recomennded.
The oil you are using is fine. Viking is talking about a 2 stroke engine. Since you are in Michigan You are probably at a low elevation so I doubt you would need any re-jetting as these carbs are most likely setup for a sea level tune. If it's running good I would leave it alone and ride it.I am running 10w-30 and i do have 10w-40 that i can swap it out with both rotella synthetic if that would make a difference
Either 10w30 works or 10w40 in summer.. I've tried just about everything in mine since 2010. Rotella syn or non-syn is great oil, I've used 15w40 since 2012. I don't recommend the 5w30 Penz simply because I think it's garbage oil for aircooled engines. I used to run aircooled Bugs and never had any luck with Pennzoil. Long time ago, but Rotella is great for these, I think.I am running 10w-30 and i do have 10w-40 that i can swap it out with both rotella synthetic if that would make a difference also got some 5w-30/40 Penz
That's exactly what I do. The higher the second number the higher of a temperature it can reach before losing viscosity.Either 10w30 works or 10w40 in summer..
