i dont think there will ever be a solution to the SP1's cooling that suits all occaisions, i tend to steer clear of congestion and town riding but on the odd occaision that i do get caught out i find the setup i have now keeps the temp between 95-110C at a standstill but very quickly cools to below 75C once i get moving, and it has been documented that the power output is greater on the cooler engine. The standing temp with the new lower temp switch should be even lower once fitted (HOPEFULLY). The cooling issues on the standard SP1 are not a real problem on a healthy bike, however, after my left rad holed and i had it repaired losing two water channels, and the HC pistons were fitted causing more engine heat i decided to pre empt any cooling issues. My left leg is protected by Bacofoil
As for using Firestorm rads i have not considered this, but if it is a workable, cheaper alternative then it can't be bad. SP2 owners are lucky as they can cook both legs evenly
