Engine mounts - arghhh

[Black Sheep]

Metric threaded bar. Oh dear, naughty chair for you. Fit the correct items and save yourself a lot of grief. Any of the reputable suppliers will provide a set of correct set of engine studs and bolts. Don't be a cheapskate. Do it properly! I almost added FFS...

Problem is, I like the bike to be out on the road more than I do seeing it broken (again) in the garage.   TBH, I'm getting past the point of paying a small fortune for bits that are going to end up on the road.  The stud's a temp fix to get me on the road again, despite the (well received) warnings.  I lost the metal battery strap down the road some time ago, and found an old leather belt with thick rubber matting top and bottom almost eliminated vibration (and battery failure) and meant the battery wasn't doing a jig under my seat - works a treat!  I've had quite a lot of failures so far so am working out fixes on the way- some conventional, some not. 

Cheers again all, let me know if anyone has a spare engine mount

The answers are three.......loctite,loctite and loctite

Point taken Peter, but I reckon I'll be spending a lot on Loctite!

Loctite, yes & maybe according to what and where, but, repeating my posts in case some has missed them, try to get some wedge washers, and get an aha & wow moment.

Have used them on cars\bikes. it's the high-tech solution to vibration consequences. They were mandatory for vibration prone equipment at the factory I used to work, building mechanics\electronics for army\navy\oil platforms.

Correctly mounted (torque), they simply don't come lose, on the contrary, if some losening unexpectedly should occur, these washers starts their intended work, locking things with more strength the more things try to get lose.
For disassembling, one solid wrench movement to break the locks, replace with new washers when reassembling.

Should I weld the b****y thing up

You could weld one of the nuts to the stud creating a bolt.
Lots of stainless nylock imperial nuts on ebay and not to expensive.
Some good info here......
