You wont find the M10X1.25 at mcmaster in SS, so dont bother, if you are looking to go that way. There are a few guys that sell them. The exh are m8 x 1.25 but with 12mm heads not the standard 13, if you are using a FP

Ya I found that out, what's the big three on the head pipe tho? Those and the exaust are the only non Allen head bolts I have on my ski now

the three on the head pipe: M10x1.25

The eight exhaust manifolds bolts: M8x1.25 for 61X and M10x1.25 for 62T
However, the exhaust manifold bolts are special in that they have smaller hex heads than a standard bolt of that size.

M10 x 1.25 x 40 hex flange bolts for the head pipe, which you can get the same plated bolts FP sends you for 1$ each at a good local industrial hardware shop. ARP, a bolt manufacturer, has them in stainless. I've found them for about 4 or 5$ each, but haven't tried them yet.

If I wasnt doning so many skis I would put together new 316 SS bolt kits together for SJ's, I have most of the data and an aewsome supplier, considering we buy a ton of hardware in SS every year. I have the correct length SS allen FP 3 bolt sets, I'm sure i could find 12mm head M8's, but you can just buy them from yamaha for $2 each

Number of turns per inch of length

that's thread count, or threads per inch. (used for American fasteners)

thread pitch is the distance between threads (used for metric fasteners)
