Haha those big ol mikuni's are from mine and my roommates 86 yamaha phazer 480's.. just doing some cleaning and getting ready for a adventure of some sort haha.
I did set the float when I first got it, before I even put it on the e50. No feul coming out of the over flows either.. I started with the stock 70 main and worked up to a 90. I threw a 140 in and worked down. It seems to like 90 but this issue has got me stumped. I know it's something totally obvious. I just cant grasp it.. if I'm not trying to rip the thing, its awesome and fun. But its killing me not being able to really open it up and get it haha I know 42 mph is alright. But still..
