Zeda 100 "Max"

I have a HF metric set like this. Not too bad… decent for our occasional use.
It’s cleaned up a lot threads for me.

Yep, I have a SAE and Metric tap and die set from Northern Tool (more or less the same as HF) that I have had for years. Works fine and I have yet to break one. Just have to take your time and don't be a dunce and put the taps in a drill.

This cheap aluminum they cast these out of cuts super easy too.

Northern tool set probably much better quality than the HF sets.

Maybe. My work set is much much better quality than the NT set I use at home. If it is better, it probably isn't by much.

Helicoil - keep same bolt as stock.

That's the advantage.

If you have no problem going a size bigger, and only have metric taps. Go to an M8. M8 is the most common exhaust bolt/stud size on most engines.

If it helps you decide, I would go for an M8 myself. Ideally it should be drilled to a 29/64 before tapping.

29/64 is almost 1/2 inch. I held the M8 tap up to a 1/4 inch bit and it looked close

Sorry, meant 17/64, typed 29 for some reason. 1/4 inch is 6.35mm, which is very tight for cutting M8 x 1.25 threads. Ideally you want a 6.7 to 6.8mm hole. Be very careful and go very very slow of you use a 1/4 drill bit. The risk of jamming up and breaking that tap will be very high.

The Ace hardware near me has the 17/64 drill bit and the M8 bolts. I will pick them up tomorrow. Thanks.

I think Rocket has already pointed that out as one of three options already...lol.

What do you use for a speedometer on the mag wheels?
