I have a 1999 Derbi GPR50. I got a new battery for it the other day and the electric start worked. However now i have to bump start it, then once the engine is warmed up i can use the electric start. Btw the old battery was dead hence replacement. Whats causing this? Cause i dont wanna have to bump start my bike every morning :/.

What terminal did u connect 1st? the plus or the minus?

positive (i think) , it worked fine the first couple of times.... Then i was riding my bike stalled it, and then i guess never the same.

Im cant remember correctly but, if you connect one of the terminals first then u risk of shorting ur electrics out.

Shocked

nah my electrics are fine. It the elctric start button works, just that the engine wont start! Of i bump start it, ride it for a bit, turn off igntion, turn it back on and press the button and rev, it works!

Probably because its not fueling right on choke and the starter isn't powerful enough to get the engine going when its cold. Try pissing around with the idle screw and move it half a turn to try and get it going.
