Thats amazing Capt Moto diagnosing a bike without seeing it.How do you know that there is no problem with clutch adjustment.These things can be marginal and are always best eliminated as it only takes 2 mins to check.If the knurled adjuster on the clutch lever vibrates loose then the adjustment can change and the clutch may not fully disengage contributing to cutting out or stalling when the gears are disengaged or selected.Also XT's have this adjuster underneath a rubber cover so it is not something that you would see unless you specifically looked for it.All views welcome.
