GL1000 Do engine guards require longer engine bolts?

#1

Post by shalbleib »

Finally sourced some engine guards/crash bars I've been looking for. They use 3 of the engine mounting bolts (1 front, 1 underneath and 1 on the triangular bracket towards the back. The guard mounts are thick (3/16-1/4") I can still get the front bolts in but obviously not as far. The ones underneath and towards the back aren't long enough to get the nut back on! Does anyone know if these originally came w/ new bolts? Doubting I could ever find them anyway. Only other option I can see is buying steel rod, cutting to length and threading the ends for nuts on both sides... Thoughts? Greatly appreciated!

Hard to tell, there are a million different bars out there and most if all the original mounting stuff is long gone. So my best guess right now is do what you have to the get what you want.

the short answer is yes. Most case guards actually came with longer replacement bolts. As most of these bikes had case guards added I would doubt there are very many OEM bolts on these bikes. In any case Honda does not mate OEM any longer and finding a source for one loooooong bolt is nigh on impossible. The other option is a threaded rod, but they have great potential for rust.

You might get real lucky and find someone on here that is removing their "long" bolts and going back to stock. They may sell them, give them, or trade them to you for your stock bolts. Wouldn't hurt to ask in the wanted section.

There could be some bikes out there that removed case guards, but retained the bolt that was used when they were installed. I have seen a number of bikes with the long bolt that was to long.

Thx everybody! I'll check the wanted section. Threaded rod would be a pretty simple fix but I'm worried about the integrity of it...?

the biggest problem with a threaded rood is lots of place for road grim and moisture to collect and lead to rust

You still need to slather it with anti-seize. If not it will corrode against the aluminum and can get "stuck" too.

Well that goes without saying to anyone who knows anything mechanics.

I have 2 sets of these engine guards that mount to the mounting bolts.
I use metric threaded rod with bolts to match, on the bottom and top rear motor mounts.
I have always sprayed these rods with Rust Check which is an anti rust produce we use up here on our cars.
They have never given problems.
I also like to replace the front top mounting bolts with the same metric bolt but long enough to accept a nut on the other side of the flange.

I personally don't use threaded rod because of the grime and rust it picks up as well as the "saw tooth" effect the threads can have when paired with vibration. My solution is probably overkill - cutting my own threads on hardened steel rod. Lot of folks use threaded rod with no issues though.

This product is the bees knees for providing a barrier against corrosion. tumb2
Mirror stem threads is one of several places I've used it on trike.
The threaded rod that captures the crash bars onto the lower front engine mount is another.
