Well as many off you know I went to BUB speed trials and had some success, some smoke, some fun, one record...
We started the week off with a mild tune up and 7 lbs of boost. THis netted me two runs 188 and 191 mph.
During the second attempt I lost communication with the brand new Haltech E11 EFI unit. The communications port failed within the unit.
We shimmed up the wastegate and turned up the fuel pressure. This is where it get exciting, during this run I was on a 215+ run (data only) when an oil line burned thru by the exhaust and just drenched me in oil. Let off a spectacular smoke screen in the process.
Took the bike back to pits got it semi cleaned up and found an oil line behind the header burned thru. The face of line was cinched thru. We repaired the line and added fire sleeve to the line.
Next run bike seemed to pull but wasn't as strong as the other runs. Made a couple more runs and progressively the boost was getting less.
Put it on the trailer and got the about 190 record certified for the AMA MPS-BF class 650cc.
Brought the bike back to denver and my crew chief and I were baffled on why we were loosing boost. Could it have been because when the oil pumped out during the third run and starved the motor for oil. (when that was said and done there was a 1 qt of oil left), could the turbo be going away, is there a plenum leak somwhere??? We were down on compression a little but not enough to worry about.
Here is what I found below and this explains everything that happened during the week. Explains the oil line, loss of power, and why I couldn't build boost every run it got worse. Repair has been made and now looking to add some more reinforcement.
We will be back for World of Speed in a few days...
