Mystery bolt

[msgt van]

I found a 10m x 1.5 bolt on my shop floor in the vicinity of where I was working in my sled. Any idea if this came off the apex?

Looks like the button head bolt for the Y pipe support

It’s too long but it looks like the engine oil drain bolt minus the copper washer

That would make sense, we had my friends apex apart to replace some tunnel protector rivits.

Not too many places that Yamaha uses the button head. Oil plug is one and Y pipe hold down is another.
Oh and 2 for the E brake at the rotor. But these are long and thin bolts.

My friend just reported in from up north. His Y pipe broke. Mystery solved.

10m?

 

[msgt van]

Yep

As in 10mm diameter?

 

[74Nitro]

There are no 1.5 pitch bolts on an apex in a 10mm diameter

Bummer
