Track bike near critical temp...sugestions???
So I just returned from the hottest track day in which I have ever participated. It wasn't too bad but +95F gets hot when surrounded by asphalt. Don't wanna beat a dead horse over this, but what do yall think or suggest I should do to achieve a lower operating temp? I know the RC51 is prone to high temp, and I have already gotten used to the 230 range. But, this last TD it was running at a consistent 240-245F during the peak heat of the day. In the later afternoon, when the temp dropped to 88-90, the operating temp did drop to 235-238. It takes a few hard laps to get it up to temp, but I'm looking to remedy this situation.
I know there a plethora of options to approach this issue, but given this is a track only bike, I'm not sure where to start.
First, even though it has fresh coolant (only 1,000 miles), I'm thinking about a coolant flush, and maybe trying some Engine Ice. Does anyone have any experience with the RC and Engine Ice...any significant temp drop??
I'd imagine radiator fins would help, but I'm inclined to remove both fans to see if that increases flow. As it being a track only rig, they're only getting in the way of the flow, and I would not need the fans to cool as if I were in slow moving traffic.
Then, there is the thought of the SPAL pusher fan upgrade. I still cannot fathom why the oem fans try to suck air into the bike vs assist natural flow. Maybe only one SPAL pusher would be the "ideal" ticket...more flow with some improved overheat assistance?
And lastly there is the pricey radiator duct cowl/scoops. They seem like they would be effective, but with the high cost, I might as well lean for the front mount radiator.
Not trying to spend too much...still pinching pennies in hopes for a set of OZ forged rims this winter.
Excuse my lengthy post, but this is a serious issue/area of concern for me. And for what its worth, while searching the forum, I read that upon one of the top mag's initial review of the RC51, they found it operating at the same 245F.
So is that it?? They just run EXTRA hot when you run the shit out of them?? Hey the overheat light comes on at 251 and it never seemed to approach 247-251, but damn, 5 degrees till critical isn't the most comforting.
Let me know what ya think, and thanks in advance.
