Do any of you have a TTR125L Owners manual, I think my sons TTR just ate the main bearings and I did not get the manual from the guy I bought it from. It would be really nice to have the manual on hand when tearing down the engine.. I just hate those 4strokes
Thanks for the link, been there, but since it's a service manual too they don't let you download it for free. And right now, I have enough to spend my money on with the yamaha parts prices
Just pulled the top end, and the big end con rod bearing is toasted too, it seems to have been very hot in there, even it's well lubed with the recommended yamalube 4st engine oil
