Time to pull apart and take out broken weisco piston pin(s).

[sledfvr]

My smooth sounding four stroke motor was ticking on my last ride, and I fear that it is a broken piston pin. I hear that weisco changed them in 06. Wondering if anyone knows what the part number is, if it is different from the old style. Also if you can visually see a difference in them. Reason I ask is I just got a set of four new 1025 weisco piston kits and head gasket on ebay for $122 shipped to the door. I haven't torn mine apart yet, but I couldn't pass up the deal. It currently has the 1025 kit and carrillo rods. If the ones I ordered are the "old style" pins I will just order a set of four "new style" pins.

Kinda nervous of tearing the motor down that far. Lots of small parts to break and lose. I printed off the motor rebuild sticky on this site, that should help, if I decide to do it myself. Thanks to everyone supporting this site.

Any input would help.

If I was you and you need to rebuild, I would pull the engine out of the sled and find someone in your area who is reputable at rebuilding engines and have them do it. One of the main expenses of rebuilding a engine is pulling it (I think Yamaha charges 17 hours?) Typically, it's going to be $800-$1000 in labor if you provide the parts and pull it your self. So the only thing you would be saving is that $800 or so by building it yourself and have a possability of putting it together wrong and be back in the same place you are now. Plus a lot of time a good motor builder can see little stuff you can't that needs taken care of, and do the little things it takes to do it right putting it back together. JMHO.

I have a set of 4 wisco turbo pins in stock if you need them. I ordered them for another application but installed JE pistons instead.
