Just took off the front cylinder and the piston is impressively destroyed (after only 275.6 km). The crown is melted in the middle and to one side; I'd be impressed if it wasn't for the fact my barrels look scored all down the sides. It looks like deposit from the piston rather than scoring in the cylinder but I suppose it is irretrievable? Can the barrels be cleaned out and used again?
I'll post a picture later if I can ever get the piston retaining pin out. I am considering just grinding the piston off!
Looking at the barrels on the tyga website and in the parts manual, there seem to be a great range of possibilities, ranging from $157 for a Cylinder B 12002-KW6-840 to $535 Cylinder A 'SP' 06121-KV3-980 or $472 for a cylinder A 'R' etc.. What is the difference? Presumably so long as I am matching the piston correctly to the cylinder I can use any type right?
Also do I need to check the rear cylinder before ordering new ones? I want to have it rebuilt for a race coming up, so I'm in a bit of a rush. I mean is a seizure like this always in both cylinders?
