Engineering Madness
I have a set of crash bars on my bike in case Matilda decides to take a nap. They protect the engine from having a sudden coming together with terra firma.
They work great and I've certainly tested them a few times. This is about the fastener choice.
Last time I was changing the oil and checking the valves I had to take off the left side crash bars to access the cylinder head. When reinstalling it I managed to strip out the socket from the longer of the bolts above. I figured I was just applying too much torque or something.
Today I was going to get a replacement so in case I need to perform a roadside repair I would have an intact bolt to play with.I went down and checked on my bolt size gauge.
6mm? Nope.
8mm? Nope.
1/4"? Yep.
1/4-20 3/4" bolt.
1/4-20 3/4" bolt.
This set has three metric fasteners on each side and a single imperial one. Who does this? I can see using one or the other standard for any given part. Knowing that this was going to fit a BMW matric would be the obvious choice.
Then throw in a 1/4" bolt just to spice things up.
Seriously?I'm honestly tempted to drill and tap in an 8mm bolt to replace it.
