I am thinking of rebuilding my derbi to a 70cc.
it is currently standard and its 2005.
i was going to buy a race crank, bearings & seals, new exhaust, 70cc top end kit & race clutch plates.
i was wondering if its better for me to go pre mix or will my oil pump keep up with the 70cc kit?
What is the ratio for 70cc pre mix?

Hello there, i have recently purchased a Gilera SMT (Derbi senda) 50cc but it has a Derbi engine in it at the minute.
Basically when i rode it back from where i purchased the next morning, there was a small puddle of water on the garage floor, upon inspection i noticed there was a small hole in the engine, (very tiny) letting this water out, i realised that the temp sensor was long gone, and this was obviously the problem, so i bought a new one, fitted it and still, i am getting this puddle of water on the ground shortly after i use it.

Now is this tiny pressure outlet hole literally the size of a cocktail stick meant to be here? As this is where the water is coming from.

DERBI Discussion / Derbi Senda DRD Pro 50 Help Needed!!

Hi all,
         I have recently bought a Derbi Senda DRD Pro 50 as a non runner and i am having trouble finding what the issue with the bike could be so i thought you could all help :) :D

The bike runs (sort of) when you bump start it or kick it, although it soon cuts out if you give it a lot of revs it can actually run and we have done about 200 metres on it but as soon as the throttle is let loose the bike cuts out, the battery is fine but i think it could be something around the elctrical side as after inspection it appears the engine is perfect, my ideas are maybe there is a loose connection which is flickering on and off.

All advice taken so please help :)

Regards Brandon.
