Suzuki Don,


I am definately replacing the bolts. But since I have no precision machinery to do the necessary tapping I'm going to play it safe and order new bolts of the same cut and thread.


Thanks guys!

You don't necessarily need precision equipment for this task as the drill bit will centre itself in the hole as it cuts away the old aluminium threads. You just need to hold the hand held drill at 90 degrees to the head and the drilling will come to a halt when you hit the bottom of the hole. Use 6mm X 1mm pitch RECOIL inserts which are the same as the original threads. The appropriate drill size is stamped on the RECOIL packet/box and is usually an odd size, so make sure you get the correct one. Close enough here is NOT good enough.

I have just completed doing the exhaust threads on my head as well. These were 8mm X 1.25mm pitch. These I had to do with the hand held drill as these threaded holes are not square to the head. In fact they are all at different angles. These threads are notorious for stripping and snapping bolts as well.
