Hi guys , I've hit my first hurdle which I'm sure will not be my last , when trying to remove the front wheel I tried to unscrew the speedometer which already had a slightly rounded head and made it worse . Any tips on how to remove the screw and also where I could get a new one would be great thank you

Have you tried an impact driver? A really useful part of any toolkit when dismantling bikes.

Hi there, You can look up on flebay for bolt removing kit. They are not all that expensive and You have a good chance You will need to use it few more times in the future 😉

ive used either a small chisel or a screwdriver to remove these. persistent tapping rather than a good wallop. place your chisel as close to the edge as possible and work your way round.

Drill a small hole in the center of the cross about 8mm deep and
get a good quality torx bit slightly larger than the hole tap it in and undo with a
small socket.

Thanks for everyone's advise will attack it again in the morning

Can anyone recommend the best place for spare parts? I.e a new screw that I rounded off on the speedometer attached to the wheel , thanks

A good old fashioned hardware shop is always a good bet. Sadly House of Hastings (used to be thorcraft) has gone, and I think even Mozeley's in Castle street has gone now. A seller on e bay called "massive attack" has a wide range of nuts bolts etc, in bzp or stainless, he does any amount, and his postage is very good.

if I remember that screw is the same as one that holds the tacho cable,
slight domed with a countersunk head,

+1 on Rich's method :) ... I do that all the time. Or Mig weld a blob of weld onto the head and then file a couple of flats onto the blob and use Mole grips to remove it while everything is still hot. Remove the plating first though

However you do it do not hit too hard or you will break the speedo drive, even more so if you are undoing thr tacho one

I had the same problem with every phillips head screw on the bike. In the end I removed every screw with an impact driver, they're invaluable. Also get a set of drivers with a metal hexagon at the end opposite the blade. These you can impact the screw with to break the galling and get a lot more torque on with a spanner or socket.

Therein lies the problem, they're not Phillips screws, they're JIS! Using a Phillips driver will cause it to 'cam out' and slip if any serious torque is applied.
This page explains, with a diagram.

After taking all the allen screws out of my bike and going back to the OEM silver chocolate ones, buying JIS screwdrivers was essential, I found a reasonably priced pair on eBay.

Yes understood but I call them all Phillips screws. I had the right bits for the impact drivers and screw drivers so rounding wasn't a problem only getting enough torque on them to move them. My bike and engine were seriously corroded though.

If you grind a small amount from the tip on a PH2 it will fit a JIS without camming out.

Thanks for everyone's help , I'm sure it will not be long until my next post !
