Guys, I acquired a 99 ttr 250 that needs a lot of attention. It appears the rod bearing burnt up and there is all kinds of metal shavings in the oil. I have been working on tearing down the engine. I was trying to take the rotor off without the sheath holder and the monkey wrench I was using dug into the metal. Will this be an issue? Hoping i will not have to buy a new rotor. Thanks in advance for the help.
