Nice pick. Everything sounds normal to me minus the word ''kickstand'' ;-) I would rip that thing right away without any doubts.
Check front sprocket for exesssive wear. Inspect swingarm bearing bushings.
I use winter friction Trelleborg tire on front and a normal rear motocross tire with near 250 3/8 ''holiday'' ice racing screws with no inside lining. My friends use Trelly's too and Gripstuds.
