the clutch is dragging then,i bet it also goes into neutral when the engine isnt running easily ? if it has a hydraulic clutch bleed it if its a cable clutch adjust it so there is 2 mm free play at the lever and if its still dragging it coukd either be a grooved clutch basket or warped clutch metal plates.
getting a manual would be a good idea - fuses are under the right side cover or under your seat - usually very easy to tell a smoked one as its contacts inside are either broken/ burnt or gone
manufacturers information is always correct on tune ups and maint. schedules - here is a link to nice generic schedule but for safety's sake consult your mfg for items not covered here:
