Ok pics of the tensioner fitted to my 03 bike.
1 Tensioner
2 Plunger with internal thread
3 Male worm thread
4 Exploded view
5 Torsional spring
The torsional spring is quite fine as you can see but this spring only applies a torsioal twist to the plunger which then moves forward on the thread if there is any slack to take up. It is not a push spring or anywhere near strong enough to apply enough pressure to the chain slipper.
If the spring is removed from the tensioner you cannot push the plunger back,as Pie says this can only be manually with a screwdriver.
Maybe later bikes have a different tensioer fitted to Pilgrims I dont know but this one looks fine to me.
Manual here now but will probably go back as I feel the auto one provides more progressive tension. I see more engines being wrecked by over tightening of manual version than tensioner failure of the original unit buy as Luke quite rightly says it everyones choice at the end of the day.
