Put a MPS NOS system on my Busa last summer. Ran two bottles of juice through and it worked great. Took it to the track earlier this year and when I hit the "button" the bike would bog and fall flat on its face...thought maybe I had a leak and just air left in the bottle. Refilled the bottle and took it to the track last night...same problem. I can hear the "whoosh" going into the air box so I know somethin is making it there. One of the guys at the track said I may have pressure problems?
Why? Worked good for the first to bottles under relatively same temperatures - why doesn't it work now???
