I bought a used 01 wr426 this summer from a dealer. The bike had difinitely been used. When I got it, I noticed that it ran extremely hot. On one night ride, I noticed that the head pipe was glowing orange while riding! I had a mechanic check jetting and timing items and he made a few adjustments. Then I went to change the oil and a noticed a lot of metal fragments in the oil filter. Should I dump this piece of s**t, while it still runs? Any imput is welcome. Thanks!!
