What kind of runner, carbed or fuel injected? If its carbed the first think to try is another spark plug.

Possibly blocked main jet in the carb, fairly straightforward to strip it down and clean up the jet, poke the holes through with a nylon bristle (toothbrush or similar) DO NOT USE WIRE!
Could also be that the air filter wants cleaning.....wash it through with petrol and then apply a little oil.

Ok,let's start at the beginning....when you say "cutting out" do you mean total electrical failure,a loss of spark? or do's it seem to be a fueling problem? could you ride it round all day at 15mph?
Has this problem occured suddenly or has it been a gradual process? Is the bike getting harder and harder to start?
There are so many things that this could be,could be fuel flow,could be spark breaking down,could be airflow,knackered rings,anything.
We need to find out exactly where the problem lies before we can rectify it.
Feed us as much info as you can Thumbs Up

its working now i changed the jets on it but there seems to be a lot of play in my throttle i think its broken because it wont rev as high as it use to.

My nephew has a 56 plate Guilera SP50 and we are finding the manual hard to understand. It's a question about engine oil. We can see the hub oil dip stick. Need to know where the engine oil goes and what oil is the best to use. Any help much appreciated Smile
