Hello everyone. 
I'm new here and I have a problem with my son's bike. 
It's a TDR 125 1993 and starts fine and runs ok until the bike is actually moved forward. 
 
Now I have checked the sidestand switch with a multimeter and all is well. I have even bypassed it too. 
We have also changed the 2 relays under the seat as I believe they are too related to this switch, but the problem is still there. 
Has anyone else encountered this or could anyone shed any light on the problem for me ? 
 
Any help would be greatly appreciated.  
 
Many thanks, 
 
Gary.
