All that means is that they'll make white sparks instead of red like steel... :goofy: Go ahead and slot the oil cooler holes then, it really can't hurt to do it, especially since it's so accessible at the moment! 10 minutes and a Dremel is all you need.
Sorry if that comes off as pushy, I'm just one of those OCD, anal types about how a bike goes together... :warranty:
At this point the bolt heads don't so much contact the oil cooler as they do whisper sweet nothings gently into its, uh...fins. The oil cooler mounting tabs aren't slotted, but they have big holes for grommets. We removed the grommets (too bulky) and pulled the cooler as far forward as possible before mounting it firmly, so I'm not worried a bit about future damage. The OCD child in me wanted 1 mm of clearance, but we don't always get what we want
