Then you'll need the HD springs, and if you don't want the bottom end to feel lethargic from the loss in dynamic compression you'll want an 11:1 piston to go with it and we're back to "pimping" it out.Well most of my riding is trail riding. But I still want to be able to get some speed while at the dunes. That's why I suggested a stage 2 cam.
Question (from a pure physics standpoint)...
Why, in the case of the Raptor (single cylinder, dual exhaust valve), would dual exhaust flow any better than a single exhaust with the same pipe cross sectional area as the sum of the duals? In other words, if I run duals with 1.5" diameter tubing, they have a cross section of 2.5 sq in each, or 5 sq in total... so if I ran a single with 5 sq in cross section (2.25" diameter) the flow would be the same.
Ignore the exact numbers I'm using, they're just for example... but the principle stands.
Because they don't make them for the 660.i'm surprised nobody is talking about the DMC duals. I really had my eye on them, or maybe the Barkers. But i like the DMC has a welded bracket to the frame and not a clamp. the clamp just makes more peices. I like that the Barkers have more options, but more cost as well. After reading the thread by THQ i think i am going with DMC Force 4 with silencers for the beach.
