We did the Wood 555 cams on my wife's trike. It pulls really good. Also did Fulsac ceramic pipes, big sucker stage one air, adj push rods and TTS. Happy so far with a few thousand miles on the build. Mileage is lousy (30 - 35), but not much worse than before the mods.
Who did the TTS tune? Might be some mileage improvement if the tune is on the rich side.
