Got the same problem with my FZ1 snapped a stud level with the bottom of the nut. MY eldest is a plant fitter and used to getting seized studs and bolts out we tried for 4 hours yesterday to shift the little foccer it's still solid. Used plus gas , heat, broke a stud extractor, hit it with small hammer, big hammer, heated it then freeze spray. One last try tomorrow after another days soaking in Plus Gas then the little b*****d getting drilled out and the hole taped. Does any know if the t**ts at Yamaha used lock tight when they fitted the studs.
