clunk on switching off engine
 
hello, long story but my girlfriend and i have 3 tenere 1vj's and we've test ridden a couple more. almost all make a metallic 'clunk' noise when the engine is turned off. it sounds like something is jerking and clouting the underside of the petrol tank. nothing seems to be being damaged, but it is very disconcerting. we were wondering if anyone else has had this problem? or if anyone knows what it may be? cheers in advance, karl.

Clunking
 
Perfectly normal, both my IVJ and 3AJ do the same thing. If you search the forum you'll find previous posts on the subject explaining what it is. From memory it's something to do with the starter clutch disengaging or engaging. Nothing to worry about although I do agree it is a bad noise to be hearing!

No worries
 
It' s the starter clutch, they all do that.
The large gearwheel on the crankshaft only engages with the crankshaft when it's speed is equal or higher than that of the shaft.
When you stop the engine, the gearwheel tries to overtake the stopping crankshaft, which it cannot, and this produces the 'clunk'.

Yup, its fine. Even my 2003 XT600E does this. Its the starter clutch
