I am going to replace the leaking base gasket on my 2006 TW200 soon. I have read and watched the videos on doing this. My question is why take the wrist pin out and remove the piston with the cylinder? The new base gasket should fit over the piston. I would think it would be a good time to inspect the piston and rings (Old two stroke rider ?)? I have all the parts but I didn’t purchase the wrist pin clips. I also have the piston ring install tool.
