Hi guys. Got myself a derbi senda 2018 as a toy. Great little bikes. I've just run the bike in and now I want to see what I can do to add a bit more power. Its a euro 4 model so I've just fitted an unlimited ecu. 14t front sprocket. Scr corse chrome exhaust and currently I've fitted a 94 main jet. It's not running well. I was told the atomiser needs to be swapped. How do I get it out? Are there any other riders on new derbi senda or aprilia sx here? I'm curious to hear of other people setups
Are you trying to remove the atomiser bushes or the atomiser itself? To remove the atomiser you will need a good heat source (not a hairdryer) and some extra piping.
