I know. He never even takes it to 2300rpm, but said he will for the break in, to get close to the 2800rpm. Ugh? He does lots of idle, lots of warm up before driving, etc.... He will stand on it for accelerating the empty truck, up to 1200F EGT, but there is black smoke rolling from the pipe when doing so, so it is over-fueled because he has the screw turned way up. A measured dyno pull will at least put a decent load on it to any desired value, but he really thinks the bottom is going to fly out if he follows the TM. He believes it will live much longer "if he is nice to it". Well, he's done 2 rebuilds so far on it in less than a year.... I hold my Sea-Doo engine wide open throttle for hours on end, and the most recent compression check showed about 10% above stock spec (a little carbon on top), after 19 years if using it that way since I rebuilt it.
I should not be beating him up. But after doing this a second time, I would follow the manual to a T.
Oh yeah. And he calls me a wuss? 2800rpm or back at you, silly rabbit.
