Longer Engine mount bolt

[Guest]

On my 81 GS650GL

I bought a pair of case savers. They look pretty nice, but the existing engine mount bold is about a half inch too short, once everything is installed.

Does anyone know the thread pitch and bolt grade, so I can buy another one?
It's about 8 1/4" and needs to be about 9" to work for me.

If you follow the link http://www.bikebandit.com/1981-suzuk...650glx/o/m6093 , Go to Crankcase, and look at item #30, you'll see exactly what I'm talking about.

William,

Would #31 on that same schematic be too long? Possibly.

I'm not a big fan of BB #s, but if you look at Babbits online,

Look at their schematics it will show the bolt size and length. (10X200)




#30 appears to be M10, at 200mm long. (7.87 in)


#31 shows (10x250)

Yea, possibly too long. Maybe add some washers?

Or, you could check out other machine schematics to find something in the 230mm range on a M10. (≈ 9 in)

On the Grade, not sure if it is 8.8, or the 10.9....

Aslo don't be confined to Suzuki, I would try other makes too. No one will know the bolt off a Honda to one off a Suzuki unless it has an "S" on it.

just buy some M10 stud bar bearing in mind the right length including washers and nuts. will be perfectly ok

I did the same on my 750L. I still have some of the threaded rod I bought at the time. I think it's 10mm....I'll throw a caliper on it to be sure.

You're welcome to have a chunk of it. Send me a PM if you're interested.

Great suggestions, guys. Thanks.

I'd be totally fine with some bar stock. I wasn't sure the 10/100 meant M10 threads, or something else, but now I can bank on it.

I'll send a PM your way, and I can pick up some nuts at the Autozone or whatever.

Getting Paid tonight at midnight, so I ordered the saddlebags I was looking at. Whoo! Is there ever a good system for locking them?
