I Have Seen Vids On U Tube, Just Pick Up The Back Wheel By The Bike Seat And Kick The Peddle Down With The Clutch Released (engaged). Jim, Dvdtz Rode Up Here Today, He Likes His Copper Exhaust Gasket. (7 Hp Wow!!) He Took My Diy Cvt Belt Drive With Freewheel Sprocket For A Nice Cruise. He Wants One!! Later I Asked Him If He Wanted To Take If For Another Ride. Big Smile, Y E S. We Started It Up And The Cyl Head Fin Melted Thru The Gas Tank. I Think You Call That A Dnf!! I Still Dream Of 7 Hp. Ron
