Derbi erhöhter Benzinverbrauch?
Hallo , ich habe folgendes Problem bei meiner Derbi 2012. Als ich das Moped von meinem Bruder Übernommen habe, bin ich mit dem Hebo auspuff 100km gekommen. Dann hab ich mir mal 70ccm eingebaut, und nach etwa 1 Jahr bin ich wieder auf die 50ccm umgestiegen. Doch jetzt komme ich nur mehr 70km. An was liegt das? Der Kolben ist LEICHT Angerieben. (Wirklich nur leicht) Mach das 20km aus? Hab auch volle Kompression denke also nicht das es daran liegt. Ich fahre jetzt halt immer mit Choke, würde es einen unterschied machen ob ich mit Choke fahren, oder eine größer Düse rein gebe? Müsste sich doch wieder ausgleichen oder? Bitte um Hilfe. Danke

I’m always driving with choke
Well, you don’t have to wonder where the gasoline will stay…!
Does it make a difference whether you drive with a smaller nozzle for it with choke or whether you drive without choke and for it with a larger nozzle?
First of all: it must be an ignitable mixture into the combustion chamber.
The choke ensures reduced air supply, the mixture is then overgreased and actually only detonates for the cold start.
If the engine runs well with permanent choke, it can actually only mean that there is “cold air” pulled somewhere (e.g. gasifier foot seal broken or anything else).
Even the fitting with a larger nozzle KANN actually only provide a worse running behavior.
Thus, I would first ensure that the entire tract of the mixture preparation is correctly sealed and adjusted.
The use of a larger nozzle or “choke operation” is countermeasures so that the engine is running at all, but the actual problem is not eliminated.
I’ve done a bigger nozzle in and can now drive without choke. Come back 100km. Thanks for your help
Jo okay. The piston is only slightly rubbed, not “frenched” I’m trying to find the best nozzle, so I can drive without a choke without getting a “fiber”.
If the piston has “frenched” and is over, you would certainly not only see it, but also remember the performance.
In the case of two-strokes, it could even be the reason for the abrasion when a mixture to be leaned by false air enters the cylinder.
Finally, the two-stroke unit depends on the lubrication by the fuel.
Less lubrication = more friction, then you can negotiate a piston eater!
And on the way there is a higher consumption possible…
Okay. Thank you, I’ll deal with the problem. You think that the slightly roughed piston is also a problem. I’m sure he’s not ideal, but do you think I have -20km? (Is really just slightly rubbed)
