Duck tape the flipper wide open and point at forest . Take old helmet . Scratch up the sides . Old jacket, tear it up . Hello insurance. If you torch it and they investigate they might find all the motor problems. I’m sure Yamaha has a record . I wish you the best of luck . If someone sets up the go fund me page I’m IN !!

I’m not so sure, I just ran one here on the stand and the oil looks all foamy after being run. I think it depends on the brand of motor oil how foamy it looks. Quaker State 5-30 ultimate durability doesn’t seem to foam like that though. there is no way this can continue to happen with three new engines.

My oil also foams up in that hose and also rises, but all is good.

I'll be passing through Clear Lake on Monday. Want me to pick it up and haul it to the scrap yard?

On a serious note, you 100% sure it's coolant in the oil?
It seems like if it were coolant in the oil the site tube would be reading higher.

Its higher now. Way over max. I came up with the oil right in the middle of the lines. It’s not the foam its the level keeps growing the longer i drive. It’s parked now on a friends ski doo back upIt seems like if it were coolant in the oil the site tube would be reading higher.

If you have all documentation, which I’m sure you do, I would be looking into the Lemon Law! This totally blows!

Has the coolant pump ever been changed or have they just transferred the original to the replacement engines?

It's disturbing to see the amount of PEFI engines going down lately. My one buddy has their bundle of tunes and runs a Alpha CAI along with a Sandale 3" Hyperflow. Now that I think about it, it must run up there around 21-21 lbs of boost as it hits the boost cut when its cold out. He can't run on Stage 3 without running a boat load of booster in it either or the dash lights up. Most of the time he runs it on Stage 2, but I know the Det protections will flash the dash. I wonder how lean its really running? He has no AF gauge or anything so he'll never know. I hope it keeps running for him.
