A bulletin was sent out to racers about this problem & also the octane switch being wired incorrect.I think it was the waterpump that didnt get lubed at the factory & you had to pull engine to do the job.

A/C has also had some engine failures with there 440's this year.

all the those 440's come punched to the max for racing, so the life of those motors will not be as long as atrail sled,
heck cats new 440 is close to 100 h.p. WOW

Not to get negative about things but after having been down this road before, I view the f5 and f7 as a race sled and a 1st year sled also. Buy at your own risk..... Or wait a year till bugs are worked out, this is what I am doing.
