The "Finned Egg" came along before the OIF was foisted upon us.
Xenor Diode Heat Sink
The bracket I've been supplied comes with a pre drilled hole on the section which would mate with the bike.
It means drilling into the Bottom Yoke Stem.
Imho, no ...Being a non welder and without welding gear, I
Do you think that would do the job with minimal technical input.
Says you're planning to lie under the forks with an electric drill, pushing the bit into the bottom of the steering stem? I'm guessing you don't know about lubrication and cooling when drilling steel? Try entering something like, "drilling steel" into YouTube and watch a couple of the linked videos ... Without copious amounts of cutting fluid, the drill bit will heat up and blunt very rapidly.To get good access I'll need to remove the mudguard, front brake and wheel
Not sure what you mean by "a tapping or metal screw". I don't know of any way except by tapping the drilled hole for a bolt?hoping to bolt or screw the bracket into place, maybe using a tapping or metal screw.
Having drilled and tapped a hole in the steering stem or lower yoke casting and bolted on the bracket, you can't be sure there'll be clearance for the heatsink under the headlamp shell. Even Triumph couldn't guarantee it, is why the heatsink in your images has that stepped bracket ...orientation won't be ideal as the Heat Sink might end up either a little too low or a little too high.
To fit a lump of metal whose only function is aesthetic, only you can decide ... However, imho a design principle worth keeping in mind is, "Form Follows Function" ...Do you think it's worth it?
