while trying to remove inspection cover on primery  i striped screw head it was the easyest screw i have ever striped it wasquite light alloy type stuff and i think it had been put on to tight by dealers

 

Lightly cold chisel it around till it comes loose then replace it and any torx bolts with allen bolts ...i did
Crasher

well thanks for that crasher i should have thought to try that my self

I stripped a couple of torx bolts on my old sporty, I found drilling the head off works well.  Once the head is removed the rest of the screw usually can be turned out by hand.

had a similar problem myself when I went to do the 4,000 service, but took it back to the dealer before did any real damage.... the laughable part was the dealer suggested it had not had the 1,600km service.....

thanks for that you lot it s only a silly little thing should have nown to try the chissel but willd im 2 to 3 hours away from dealers and if any thing goes wrong its a hassle

As KC said drilling the screw heads is the fastest way if your comfortable drilling in that area. I'm not so here's what I did when I found the primary screws were way too tight from last dealer service:

First up make sure you use a T27 for the initial attempt, and not a T25-- no saying you did but some do thinking that T25 is the correct size.

After stripping 3 screw heads with the T27 I used a T30 bit only and tapped it into the stripped screw heads really tight. If this would not have worked I would have then drilled em.

I then used an impact driver with a socket on the end that fits the T30 hex bit. I had to reduce the drive size for this.

The impact driver broke them loose easily, and I replaced them with stainless allen key socket head screws.

I used a small amount of never sieze and torqued them to the correct spec. (I thnk it's 4.5 Nm) and now they are EZ...

Impact drivers are a great tool to have, they work really well.

I hate torx screws, but unfortunately harely loves them so they are here to stay, but here's a tip:

What I've noticed in some cases is that the torx bit is slightly loose when inserted into the screw head, even though you are using the correct site.  This is a major cause of stripping as the bit and the screw don't fit together really well.

What I've done on some of my torx bits is file off about half a mil from then end of the bit.  What this does is allow the torx bit to sit further down in the head of the screw and as torx bits taper out as they get lower you get a tighter fit. 

Obviously be careful not to file off too much, but I've found they work a lot better after having done this with some bit to screw combos.
