steve Posted July 12, 2006 Share Posted July 12, 2006 Does anyone know why my sr125 backfires through the exhaust when coming off full throttle and slowing down? It doesn't happen all the time but is rather annoying when it does. I have tried cleaning the carb but this did not help. The bike also stalls sometimes when it's hot and stood at traffic lights and junctions. Link to comment Share on other sites More sharing options...

phillipw Posted July 19, 2006 Share Posted July 19, 2006 A common cause of backfires is a leaking exhaust system (blown gaskets, joints,,etc.) A for not running nicely when hot, when were your valve clearances last checked ? Link to comment Share on other sites More sharing options...
steve Posted July 23, 2006 Author Share Posted July 23, 2006 The exhaust is only approx 6 months old a new copper gasket was fitted when I fitted the exhaust. And as for the valve clerances I checked and adjusted those only a couple of months ago this is partly why it's driving me mad and I have run out of ideas, maby it's a trip to the dealer next!
