Check to see how deep the hole is and if its closed at the bottom.
If possible, I would use the head as GUIDE FOR DRILLING AND TAPPING the block ONLY.
As stated earlier, put some tape around the upper 7/8"s (or so) of the drill bit so you DON"T drill/damage the head. Your basically just using the head as a guide for the drill bit/tap.
If your not comfy with this kind of work, bring it to a machine shop. Shouldn't cost much to do..
I'd remove the head for cleaning out the metal shards. You won't need the head on when actually inserting the coil
Yeah it was fugly back then too. With the GPz550 it didn't stand a chance.
If the tap is too wide to fit in the head, you can use a block of wood (2 x 4) drilled out JUST LARGE ENOUGH for the tap to fit in. Use a drill press to get a 90' perfect hole in the wood (or metal at least 1.5" appox tall)
That'll hold it nice and perpendicular to the block. Once you get some threads on it started (and straight) you can simply lift the wood away..
that valve shim is NOT good.... Time to paddle....
Insure it to the hilt, wait 2 weeks and push it over a cliff.
