mickb Posted May 17, 2011 Share Posted May 17, 2011 Hi All, I removed the motor from the bike to paint the frame etc and rebuilt the bike, i had the carbs bead blasted, cleaned them out and replaced the pilot jet and float needles. I also replaced the inlet balance rubbers. On starting the bike it has developed a flat spot and only improves with the choke on, one side exhaust is running hot and the other a lot colder. i also replaced one exhaust for a better condition one. Would replacing main slide needle and jet help and also reed valves? Or should i strip the carbs again and check for blockages? The motor ran fine before which is also a bit confusing, any sugestions will be greatfully recieved. Thanks, Mick. Link to comment Share on other sites More sharing options...

Mick, if it was running fine before the carb strip down , theres your answer , i think they need rebalancing if you have not done that yet , have you put new cables or disturb them form the original routing deffo carbs Link to comment Share on other sites More sharing options...
Moderator mervin Posted May 18, 2011 Moderator Share Posted May 18, 2011 I would go with checking the carb for blockages bead blasted could mean a bead stuck in an important little hole, Merv Link to comment Share on other sites More sharing options...
