[QUOTE="Andrewaust, post: 84644, member: 936"] Yeah the big question is why did it seize, usually rings if so badly worn to cause a seizure would score the bore and take out the piston, something like the piccie I'll post just below - this is a two stroke but you'll get an idea, fine dirt getting into the engine of WR/CRF's etc are causing ring and valve problems. So damn hard when you cannot inspect something yourself, I use to fix bikes, cars, trucks and moved into other things, but still sometimes fix friends bikes, anyone with a CRF, either before or after 05, I recomend going stainless steel valves with the proper seats and guides, the WR's don't seem to have many problems, long as you keep the fine dust from getting into the engine, we call it bulls dust here in OZ, it's like talcum powder and stuffs everything. Wish I could be more helpful. [CENTER][ATTACH=full]6621[/ATTACH][/CENTER] [CENTER] [/CENTER] [CENTER] [/CENTER] [/QUOTE]
