Check your Y=pipes

[dmkhnr]

SOB, the machine screws backed out of my slp Y=pipe and it rotated down on the cyls as it's being held on with 1 screw.
I had it apart this fall, and I know your supposed to bolt it up semi snug so the silicon can dry before you tighten. I'm 99% sure I tighened them up but all but 1 backed out. Must have forgotten to finish the job.

It came apart when I was heading back to the truck, so I rode 2 miles loud and proud. (I actually limped it back as I knew something was wrong).

That sucks the same thing happened to me when I put a D&D on my 900 cat.Heat cycle then re torque ?

i'd skip the silicone next time, always find it funny the suggest to use it.

[dmkhnr]

I'm riding today, so I'm not going to silicon.

Silicone, yes. Make sure you use loctite. I like the med hi temp for that area

[dmkhnr]

Sled ran like a raped ape today. I needed new header gaskets as the custom ones that I made tore in half.
Just put it together with the stockers without silicon. I'll make some new ones up this week and install with lictite and silicon. I used anti-sieze last time, what do you think?

the 'doos have had y pipe bolt issues for years, read that some were twisting off inside the jug when loctited in after falling out once. peeps would go to remove them and they snap off, most use nordlock washers for that reason.

invest in a little thing nordlock washers
yep, our doos y pipe bolts have come out since 03 and they still do on the 2010's

once put on, they will never come out
