I've got a serious tl problem.... this weekend I jumped on my tl, ran it about two miles down the road, came to a stop at a light and when I started moving again the engine made a loud knocking or slapping noise and stalled. Tried starting it again and engine turned a little and froze after one loud knock. Oil level was good and bike was warmed up before riding. Tempeture was always normal. Engine will not turn unless pushed back in 6th gear. ANY IDEALS, PLEASE HELP!!!!!!!!!!!!!
