I went for a 20 mile (woods/street) ride the other day. The bike ran beautiful in the woods, but experienced some hesitation at about 55 mph on the street. Along the way i stopped to rest. I happend to check the oil after 10 minutes of sitting and noticed there was no oil showing on the dip stick. I had been pushing out some blueish/white smoke. I realize i probably need to have the engine rebuilt (bore, pistons, rings, valves ect.) If i am burning that much oil shouldnt the bike be running poorly in all riding situations ? Any comments is much appreciated.
