Re: Nut/Bolt sizes for 2 stroke kit
Except for the fuel tank mounting fasteners, which are 5mm, almost everything else is 6mm X 1 thread. The cylinder head stud/nuts are 8mm. The threads on the cylinder studs vary. Some have course threads on one end, or 8mm X 1.25, and some have fine thread on both ends, 8mm X 1. I've found them both ways.
The lengths are different depending on which fastener you're dealing with.
I hope that helps a little.
