i took my 98 speedfight out for a spin and i was going down a hill and suddenly the engine lost all of its power the engine was still running and when you gave it throttle it started to move forwards but very slowly so i started pushing the bike home and the hill was very steap so i used the engine to get it up there then half way up the power came back and it was fyn, a week later the same thing happened. however the belt has not snapped and is in good condition so i thought it must be the rollers could anyone help and solve my dilemma.
the ecu is the brain of the bike this controls everthin from fuel to your lights choke theses can be expensive one way of tellin is when its does lose all power turn it off and then on again if the power comes bk then this is ure prob email me or im me if uhave any probs at waller567@hotmail.co.uk
