bantamjames Posted January 19, 2014 Report Share Posted January 19, 2014 (edited) Hi again all, I have come to all to ask for a small amount of guidance, I recently picked up a 1987 Suzuki TS50X as a winter run around in anticipation of the icy/snowy weather. It was rather battered but after a large delivery from Wemoto it is a good little bike except for the running of the engine. It will start from cold after a couple of kicks on about a quarter throttle, it will then run for a minute (not revving over 6 or 7k happily) with choke on or off then it will die. It will then only start on full throttle bump starting and will run for less or no time. I have been playing around with jetting and float heights but i cant seem to make any noticeable changes to it's behaviour to it whatever happens. I have recently changed the cylinder for a 70 kit though it was exhibiting similar symptoms before i changed it when it was running a standard 50cc kit. So yea i'm lost and frustrated, does anyone have any thoughts? Cheers, James Edited January 19, 2014 by bantamjames Quote Link to comment Share on other sites More sharing options...
monteberg Posted January 19, 2014 Report Share Posted January 19, 2014 crank seals drawing air ????????????????????? Quote Link to comment Share on other sites More sharing options...
zerorev3rev4 Posted January 19, 2014 Report Share Posted January 19, 2014 sounds like it is flooding see what difference turning fuel off makes once started , is air filter ok and no airways restricted , float level could be wrong causing too hi fuel level ,also check for damaged reeds and they are closing ok ,check if spark still looks good after it stalls Quote Link to comment Share on other sites More sharing options...
tltel Posted January 19, 2014 Report Share Posted January 19, 2014 The not revving bit makes me think it is an electrical problem, is it points or cdi ignition?,it check wiring and clean earth connections. TLTEL Quote Link to comment Share on other sites More sharing options...
