Can anyone tell me the Ignition cover tap & screw size. Also if possible what might be the metric equivalent. I am kind of thinking standard USA sizes are gong to be hard to come by over here. Thanks! | ||

IIRC, I used a 6x1.0mm tap with the matching screw. | ||

Thanks, Any idea how a #6 screw coorelates to metric. I went to the local Japanese wannabe Lowes(its a joke) they donot sell taps in standard sizes only metric. I was reading your profille. I got my xb also after years of covet also. No test ride or nothing, bought it from Daves and had it delivered to my driveway. Havent looked back either. I only wish I could own 2. Thanks again. | ||

The above tap size posted by 12r is metric  (Message edited by sokota on March 08, 2008) | ||

If you're talking about the riveted on cover, that uses 1/8th" pop rivets as it comes. So the holes that are already in that that would be about .125" dia. Sizes on Imperial screws that will work are: #6-32 O.D. = .138" (#36/.1065" tap drill) #8-32 O.D. = .164" (#29/.136" tap drill) If you approach it with some skill or "feel" for when a tap is about to break, you can probably just use a #6-32 tap to thread the holes that are left over after you drill the rivets out. It is aluminum and will thread fairly easily but some tap lube and backing the tap up to cut off the chips every 1/4 or 1/2 turn will help to lighten the load on the tap. Broken taps are bad news... The 6 mm screws are almost 1/4" in diameter (.236" O.D.) and the pitch is a little coarse at about 25 TPI. I think they are a little oversized for use there, might be a little unattractive. Whatever you use there, a drop of blue LocTite and gentle tightening is a good idea. Over tightening screws in the granular material in those cast aluminum covers will strip threads real quick. Talk to your aviation mechanics or the guys that do electronics installations and repair. They can help you with good SS 6-32 and 8-32 screws and probably have the taps and stuff too.

Do the rivet eliminator kits comes with a tap? | ||

Great user friendly design, courtesy Harley Davidson. | ||

On my firebolt I just rammed coarse threaded screws in there. I took a different approach on the Uly just cuz I was bored at work and had the tap kit there. And yes the Numbers I posted were metric. | ||

I used two 1/4-20 screws from a lawnmower. I realized I had to tap the holes on engine assembly, and was totally disgusted at that point. I thought the design was so stupid I'd use lawnmower parts for the irony. I wonder if this is Harley's way to make it tamper-proof for EPA or something? | ||

"I wonder if this is Harley's way to make it tamper-proof for EPA or something?" I would bet on it. |
