Y'all were wondering what I was going to do with the 2nd MS460, aka. that pile of parts in the corner of my shop... Well here goes. Since used top-ends for the 046/MS460 are going for stupid money on ebay (isn't everything? ) I decided to do this up with an aftermarket kit. Here's what you get in the kit. There was another kit on ebay that gives you even more for less $$ but I was impatient and didn't want to wait for it to ship from Hong Kong. The gasket/seal kit. Included the reflector foil for behind the muffler, nice touch. The exahust gasket is much thicker and a different material than OEM. The crank seals are double lip seals like the OEM parts. The case gasket is thinner than OEM and as I will show later, not an "exact" fit. The kit included a dual-port muffler, I really like this one, it has a silencer box in the middle which my OEM Oz muffler does not, so this one should be quieter. It might have an effect on power, but my guess is it will be minimal. Considering you could buy this for $30 separately, it really is a nice piece. The wrist pin is probably the most obviously different part in the kit. However it fit quite nicely in the piston's bore with the bearing (also included) I guess I didn't get a photo of the piston, but other than being 54mm diameter, it looked very close to OEM. The kit also includes a new decompression valve. I compared the included Torch spark plug with the NGK and Bosch OEM replacements. The ceramic insulator (external) is a bit longer than the OEM plugs but seemed ok otherwise. What the heck did they think I was going to do with that?
