kstar 70cc piston port
over the past few weeks ive noticed an increase in oil mix coming out from my front sprocket area, today while changing sprockets i noticed that it looks like the seal's outer layer was completely gone, (or so it looked) i could see the little metal spring that wraps around the shaft on the inside of the seal. is that how its supposed to be? ive never looked before!
what would be the performance symptoms of a leaky seal? my bike does not like high rpms and almost makes no power higher in the rev range, low and mid power is excellent though.
worth it to get a new crank while im splitting the case?
