i bought a 2 stroke kit off ebay and put it on my bike and it works perfectly and then i bought a soeedometer so i could see how fast im going and i set it up right and it works when cycling normally but once i release the clutch it starts blinking and resets and i hav to put in my wheel details and everything again.
 
Cead mile failte,

You probably need to be using a resistor spark plug then.

All these kit motors come with non-resistor spark plugs which are famous for screwing up electronics like bike speedometer computers and tachometers on these bikes.
That plug number should be an NGK BR6HS
 
If it’s one like this try wrapping the bar with padding then strap it on.

I have one like this and did the same.. kept resetting from vibes.
I already run an R plug.
Once I isolated the vibes it’s been great.
