Just like that i fouled a plug on cylinder number 4 (front right.)

was running fine and is noticably missing at idle, carbs are synced, good fuel.

Kind of at a loss.

any help would be great.

Thanks

Jeremy
 
I had the same. I put it down to needle and seat. I'm still waiting on parts at the moment.
 
Check your wet float level, that will tell you weather It's a needle and seat, pull all plugs and make sure you have spark. If you do I'd shotgun it and if that doesn't help then pull carbs for a good cleaning.. I'm having a issue on my Dyna where if I put it on the stock curve it fouls #4 but if I'm on curve 4 then it doesn't foul anymore but I've got some electrical gremlins going on so I'd suspect carbs in your case first but still check coil resistance and stuff like that, ya never know...
