Can anyone give me some feedback on the D&D 1010 or speedwrex 1000 going on an EFI, single pipe for trail riding. I know D&Ds are aftermarket castings & wrex are punched out OEMs. What about good trail machines.

Speedwerx is pretty mild mannered and with the single pipe was just fine in the trails. Fuel mileage isn't soo hot with the powervalves chocked open, but there are options for that. Gotta take care of that crank though. I'd keep the r's down as much as I could. :div20:
