Yesterday was the first time i ran my SWB Busa. It was a feeling out process and i did run high 9's with a few botched 10.20's passes. MPH was only 139. Air was crappy with 3600 DA and very humid. Alot of guys said they were 5 mph down from their usual. I am 200 lbs and a 50 lb. lighter rider went 9.80 @ 144 mph. My 60 foots need to be better. Overall had a good time and hope to see 9.60-70's. But my fatass needs to lose weight.
