Sandman,

Both Hightower & Mr. HP have some good ideas on lightening rotating mass. Here is a link to Hightower talking about loosing 7 lbs. of rotating mass, which also happens to be another thread about the 520 chain and sprockets.

Sandman:

When I went to the 760 I did the dual FCR's and Ron Wood pipe at the same time. Pretty suprising I didn't have much tuning I needed to do (thanks to Jeff's experience.)

 

looking at duals myself now but the 45 did so good at dunefest i hate to change.

 

you better go with the duals or i might be ahead of you next year at dunefest [img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img]

 

i thought you would come with the white bottle and take the turbo out at the beginning.[img]i/expressions/face-icon-small-smile.gif[/img]

 

I think RMATV sells a stainless rear sprocket
