Waste of money, just have your engine jetted right and you wont have to worry about anything.
i disagree
correct jetting isnt the only factor when considering cooling system design, a stock engine making around 40whp that is built to produce close to 80whp both jetted correctly will still have different cooling requirements.
el diablo: for our type of riding and dealing with the higher ambient temps (>37C) than most other parts of the country,so im with motogeek on that. more hp produced will put more heat into the cooling system that must be dealt with and since you arent running a larger radiator, anything you do to help cool the engine will be beneficial. also doing high speed rides to drag hills, running hard there, and riding back to vehicles will definitely testing the cooling systems.
