What's wrong with my bike?

[Moonie]

Ok, third thread in one morning on here, sorry guys.

Couple of problems with my bike, firstly, every now and then when I press the starter button it will start but the motor will stick on until it runs out of battery. I took the relay out and tested it and suddenly this went from happening 100% of the time to happening every now and then.

Next, theres the fact that sometimes, usually just after I set off, the bike it very jumpy in it's delivery, sometimes losing power altogether. This is not good up steep hills. Yesterday it did this, and then the starter motor stuck, I had to bump it and take a 5 mile detour to avoid any steep hills on the way home.

The bike is a Derbi GPR50

Any ideas?

Choke working alright ? Most bikes will be a bit jumpy at the moment due to the cold weather, till they have warmed up.
Make sure its warm before you set off.
Could also be cold seizing if you are over reving it too soon.

Starter motor sticking could also be related to the motor itself and the clutch that connects it to the bike.

Ok I'll have to start warming it up a bit better.

Choke lever is snapped, but I can still get it in and out and seems to work A OK.

What's wierd is that it stopped after just testing the relay.

Is there a chance it could be getting gunk on the points or something when it's in the socket?

Thought the running issues might just be to do with it being a two stroke in the winter...

i dunno about it just being the winter mate.
obviousey its and issue but not that bad. also as your coolant has antifreeze in it. (correct amount). warm the bike up before you ride it. keep your carb nice and clean and happy. new spark plug. mine runs fine.
