@ the end of the day it's your $$$ and bike. Gen1 fans and Gen2 fans are different, I wanted 2 do it rite the 1st time and be done with it. Got a gen2 rad and oil cooler off ebay 4 a good price and got the rest off a couple race sites like Schnitz and star racing. Didn't want 2 have any compatibility issues so I swapped the whole thing out
I hope I didn't offend you, or have you think what you did isn't the right way. There's different ways to get around cooling issues on these bikes. While a gutted thermostat isn't a good option for someone in the Midwest, it is down south here. We have 2 temps, hot and hotter. It just doesn't get cool enough. Being matts in New Mexico, he could benefit and save a bunch of money, and it will work as good.
On the flip side I'd suggest a set up simular to yours, 1busa, for people in the northern reigions as the temps swing more dirastically day to day, and a thermostat is needed to regulate engine temp.
