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
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.
