Had a good search and can find no definitive answer on this so here it goes ...

After having the Alta installed today, at certain revs there is a distinct chirping/whistling at certain throttle loads this is very evident, but as the revs increase it goes ....

I have found the thread about the breather hose and that has been checked and is fine, however is this noise normal for the alta, or have I done something wrong :confused:
