Same problem everywhere. Had a sales man at Riverside Yamaha do the same thing on a Raptor 90, not a huge amount of money but still want the same service, Went to pick it up and it wouldnt run right so they took it to the shop and said he would call me that afternoon so we left. Long story short...
I hope he is still not at it but if he is this is what i did, I took a socket the size of the nut then painted the teeth on the nut ,pressed the socket to the nut to get an imprint, next i took the angle and cut the painted pieces on the socket out, worked for me
Lots of snow up there close to 10" on the weekend close to 4 in places yesterday best sledding of the year going on now. Another 3.5 by 2 pm and was still coming down hard. Not hard to find 3.5-4' of untouched now
That is not a staging area, this is an active well with tank trucks hauling out of there on a regular basis. Its a small enough LOC as it is. Better off at the ball diamonds.
