honda 919 part number 94050-10000

Hey all, I bought a 919 about a month ago and noticed a bolt was missing. I got the nut and bolt ordered but I don't know if there's a specification on how tight it needs to be. I don't want to be under or over and I couldn't find anything online. Any word at all is helpful

A notion of where it is on your bike and what it does would also be helpful :-)

Pics of location (both sides)

Here's pics of the hole from both sides, I'm not sure what it does but given that there's not many 20cm bolts on the bike I would say it's semi-important.

Yup, It's important.
It's the rear lower engine hanger bolt.
Per the manual it's a 10mm thread dia. with a torque of 50 Nm (37 Lbf-ft)
Manual doesn't show thread pitch, fastener grade, or bolt length.

good luck

Considering your discovery of such a thing on an old bike that's new to you, I urge you to retorque all the critical chassis fasteners on the bike.
Who knows what else you may find!

Yup, that happened to my '02. The tell was every time I changed the throttle the shift lever would move up and down, indicating that bolt had fallen out and the frame was flexing. Fortunately I had a good machine shop at my disposal and made a stud out of O1 oil hardening steel of appropriate length and tightened to 2 3/4 grunts with a nine inch breaker bar (Roughly equivalent to 50 ft/lbs). No problems since.

And, yes, the upper rear bolt needed tightening as well.

Interesting that it was on the center stand while doing all the work the new fastener would not insert into the engine boss ... it was not in line. Had to put it on the side stand to finish the job.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

I'm going to go put some loctite on mine right now. I don't want to have to think about that bolt ever again...
