If your speedo numbers are flashing could it be a glitch in your electrics? Have you tested any of the circuitry? Can't think of any mechanical issue that would cause speedo numbers to flash.

No didn't try anything yet ring keeway today they said need to plug in on diagnostic in keeway dealer then i call other keeway dealer close to me and they said if is not engine warning light on they can't put it on diagnostic idk why and they have to investigate where the problem could come from but that could take all day in 1 word will cost you a lot i am not bothered to drive like that i just want to make sure the engine is not overheating that's the main worries in my mind

Check the battery leads are tight.

I'd still check the battery leads as @boniosuggested. It is amazing how many issues are caused by loose connections and bad earths. 

[simon1991]

Checked the battery cables today all looks spot on

[simon1991]

Just don't know what to do and i am worried to drive it now

Is the fan kicking in? 

 

Usually a flashing temp gauge is a sign its too hot and overheating

[simon1991]

No the fan isn't turning on and other thing is when that's start flashing i didn't see the last square H for the water when temperature is too high i mean is not showing an H for to high temperature usually if is overheating an H should come up and what could be the reason for overheating when the coolant is full

Don’t know anything about that actual bike, but a couple of things come to mind:

Is the water pump working?

Is the radiator thermostat working?

both are reasonably easy to check.

 

[simon1991]

How can i check both of them if they working can you give me a tip?

Try the Thermostat first.

Remove the thermostat & hang it in a saucepan of water, as the water gets hot you should see the thermostat open.

If you’ve got a thermometer you can see what temp it opens at.

A tip on doing the above. It can be quite hard to spot when the thermostat opens. If you put a piece of thin string into the valve then suspend the stat in a pan of deep water the stat will drop off the string as soon as it opens.

I think the diagnostic will be the easiest way will book it on Monday and will let everyone knows what's the problem so you know for future just in case

[simon1991]

Done the diagnostic no faults at all bike still overheating
