I was riding down the road and noticed a loose bolt sitting in between the shifter shaft and primary. It is a 5/16" x 3/4" Grade 8 bolt. I cannot figure out where it may have came from.

The last things that I have done on the bike were new grips, mirrors, and throttle/ idle cables. I cannot think of anything that this would have come off of doing any of that. Previously I had an indy redo the rocker box gaskets, and install a new cam. Could it have come from that?

 

remove your seat see if its one of the bolts that hold the gas tank in place

 

One of the top motor mount bolts possibly???

 

Fork pinch bolt? I think that's bigger than 5/16". JUST GUESSING.

 

Ain't them 5/16 Bolts holding down the Rockers themselves...
Simple thing to drop one...can't find the thing, put different one in!
Longer than an inch tho I think...Like two.

 

Got a picture of the bolt in question?

 

Here's the suspect. I doubt if it is a pinch bolt. The bolts that hold the tank on are torx head. Upper motor mount would make sense for where it ended up and it being Grade 8, but they all appear to be there. I'll look closer.

I looked at the drawings, and I don't think that it came from the rocker box assemblies.

 

Looks like an intake bolt, but I'm sure you looked there already

 

All my intake bolts are allen head bolts.

You know there is a possibility that (since the bike was at an indy) the bolt doesn't go to the bike..
Indy could have dropped the bolt there and not noticed it.

I'd still say it's a top center (of the motor mount) bolt.

 

And I can't think of any grade 8 bolts on the bike. At least not from the factory. Someone put that in the front exhaust in place of the stud?
