derbi senda keeps cutting out!

Help! I have just recently bought a derbi senda 50cc drd sm 09 plate, when I got it, it was running fine with no problems at all. Couple of days later it has just started to cut out on me, sometimes it starts fine and then I go out on it and it just cuts out. when it cuts out they is like no power at all but as I give it throttle you can tell it is trying to work again but then it finally comes to a rolling stop? I have recently drained the tank and quite a bit of muck come out, it lasted longer after this but eventually died again, so I bought a new fuel tap as it is a vacuum tap and this did not work also. sorry for the long paragraph but please, someone HELP!

Welcome baker97, sounds like blocked jets in the carb, if possible when it happens again give it full throttle until it stops and remove the spark plug wearing gloves (if dry then it`s fuel related), I suggest an inline filter just before the carb.

Derbi Senda

As it's a vacuum tap, the breather vent could be blocked. It's in the fuel cap.

How long does it take to start once it konks out?

hi, I will try this, and I have took the fuel cap apart no blockages anywhere in the fuel cap, and it takes like 6 minutes, it happens the most when I shift into 5th.

Cutting out

Personally I think it's something to do with my cdi as I have just removed it and cleaned it up, the bike has lasted a lot more longer but only cut out once. Stuff like this really baffles me, also when the bike is cold it is really hard to start even though it's a warm day I does not have a choke because I took it off because the cable had snapped but I wouldn't think I would need it on a 20 degrees day like this?

Hi

I are thinking like the Jaffa him right, at least yous would have ruled out the carb and if yous use a filter afore the carb you tell if crud is attemptin to get into the carb.

First off an engine makes power it does not 'get' power.


Secondly the clue to your problem is that the engine is running too rich which means one of two things is wrong or if your really lucky both are wrong.

There is too much fuel reaching the engine is the overall problem.

You now have to investigate if it is caused by the carb' being set up wrongly or having the wrong jets in the carb' or there is a restriction preventing air from getting to the engine.
