Triple Tree Pinch Bolt MISSING

So I decided to look over my R1 Track bike because i was bored and BAM I look my left top triple tree pinch bolt that holds the forks ITS COMPLETELY GONE NO BOLT AT ALL so I look at my right one it backed itself out halfway holy I guess I forgo:t to safety wire these 2 bolts Lesson learned always check your bike out and look over everything after a TD these bad boys will shake everthing loose thank most of everything else is safety wired.

These bolts are not required to be safety wired in the CMRA, or any other racing or track day organization that I know of. They don't generally have a history of coming loose and backing out on their own. Use blue Loctite 242 threadlocker on them and toque them properly and they'll likely be fine. The ones I've seen go missing could most likely be attributed to insufficient torquing.

That said, I'm okay with safety wiring just about everything. I get asked all the time, "Do I need to wire this? Do I need to wire that?" In the event that wiring isn't required for the application in question, my answer is always the same: "You don't have to wire that to satisfy tech inspection or the rulebook, but I'm in favor of safety, so feel free."

Thanks Racer997 that's exactly what I did loctite 242 blue and torqued it down properly. Ive already had axle bolts pinche bolts and caliper bolts back out cause of TD's that's why I safety wired both track bikes and my Busa call it overkill but I would rather be safe and have a piece of mind nothing that these won't back out. I would hate for someone else to get hurt cause my lack of safety or not caring.

I never have those types of problems... Pinch bolts, axle nuts, caliper bolts etc.?? You shouldn't be constantly having to retighten that stuff. Safety wire or not.

I dont use loctite on any of those bolts you mentioned.

it's good habit to give your bike a once over and make sure everything is tightened to spec.

It's not common in street bikes, Brandt, but it does happen. Keep an eye on your dirt bike because those things are way more notorious for raining parts.

Before this turns into a thread about Loctite, Vibratite, lock washers or locking nuts, let me point out that Loctite, Vibratite, lock washers and locking nuts are not equivalents for safety wire. Sooner or later someone's gonna ask, "Can I use a lock nut on my [part that's required by the CMRA's rulebook to be safety wired] in place of safety wire?" The answer is "No." It's not allowed at NASA or with Airframe and Powerplant folks, either.

Carry on.

i only had these types of issues when i didnt know how to work on my bike and took it to a local bike shop that i shall not name. I dont use loctite on any of those bolts i mentioned earlier i just put a tad bit on the ones that backed out on the triple clamp i saw this morning and torqued it down
