Just a random question about radiator caps. My WR boiled over a few times when I was riding the clutch a lot in first (duh) and second. My fluid levels seemed alright and I could see it being sucked back into the radiators once things cooled down (under 5 mins). Either way, it had me thinking about getting a higher pressure cap (I think stock is 1.1 and Tusk sells a 1.6 one).
So my question is mostly technical: wouldn't a high pressure cap be counter-productive? I mean, if the coolant is already boiling hot inside the radiators, then how is it effectively cooling the engine? You're basically keeping hot liquid inside/postponing a boil over, aren't you? Or is the idea behind a high-pressure cap: better than having no liquid at all? Meaning, keeping the liquid (even if it's hot) longer in the radiators better than no liquid at all?
Secondly, is there a way to know if you're boiling over without actually stopping to check overflow bottle level? Once when it was boiling over I heard it once I stopped the engine, but it kind of scares me to know that it might be happening while I'm riding without me being even aware of it. Then again, a few days ago I went riding and it never boiled, so I know it's mostly due to me riding the clutch at very low speed. More of a theoretical question again...
Sorry if these are stupid questions... Just wanted to check before pulling the trigger on a different rad cap.
