OK thank you, i find the 160 on the MGM little high to my taste, because lot of guys here tell that the MGM are suppose to run verrrrrrrryyyyyy cool

I'll make larger hole in my body windshield, maybe this will help a little bit too. I've 6 holes of 3/8" of diameter in the windshield, and same thing on the back windshield too, but i think that i'll completly open the front windshield.
