Sorry - could you restate?

If you mean to say "hissing noise" then it may be coming from your chain.  Depending on how loud it is, it could be normal or not.

Or it could be the front caliper scraping slightly against the rotor, which can also be normal.

probobly front caplier.... nice work kerry

well bc im so safe and i wear a helmet         i dont hear it neways

I had a hissing problem once. As it turned out, my battery drain hose was kinked up, and pressure was building up in the hose and slowly leaking out.

what was it kinked on,    ill check tht out      thnx
