Hi there, my 2002 tm recon had a chain noise coming from the crankcase when i bought it. Assumed it was the timing chain as eveything else seemed ok and the oil pressure light was going off a couple of seconds after starting like normal. Well opened the casing yesterday and found that the timing chain was perfect but the oil pump chain had came off. The oil looked clean but on the bottom of the case the oil residue was quite metalic looking. I have no idea when the chain came off or how long it was run like this. What should i check for damage from this before putting it back together? It seemed to have plenty of power when I test rode it before stripping. Should I just fix the pump, flush it with clean oul and hope for the best? Any advise would be appreciated. Thanks
