    Adding 806 cam to 525

    By adding an 806 cam to a 525xc, will I need to change any jets or just retune with existing setup. Also how much will a ported head change the jetting.

    Pretty much drop in the cam and go. Head will probably be the same. All you can do is try it and see.

    What Sicko said.. Only thing I would add is: head porting needs to be done by someone that knows what they are doing, not buddy Joe next door.

    Thanks guys. The head I bought was done by Baldwin so it should be respectable.
