Scott's 14 (First bike)

[J16SDA]

Managed to fit my cheapo bar end mirrors to see whether or not I like them and I much prefer them to the standard mirrors. I can actually see behind me so now to purchase some better quality ones. 

I need to find something to cover the holes where my old ones came off. Does anyone know the size bolt I'll need to cover them?

Put a bit of Blutac down the hole & cover it in black marker pen.

Put the old mirrora back in, so  you can admire your handiwork ans see yourself looking at your new  bar end mirrors.   

[VladTepes]

take your old mirrors to a bolt place and ask for a bolt to match the length and thread.

and then here comes the boss being all sensible . . .

J16, pretty sure 10 mm. Just find rubber plugs to fit. Thats all i have, been in a long time.

I'm sure Suzuki and Yamaha use the same thread but other manufacturers use a different pitch of thread .
As vlad says take your mirror's to a bolt supplier and happy days.

[grog]

Yeah Seth, Yam the same. Hundreds of blanking plugs/threaded on E Bay. Rubber plugs work fine.Fraction of cost.
