Areox 50 LC power problem after derestricting

[jbmk]

does the bike have a choke? or is it all auto?

if it has a choke go for a ride and apply a little choke and see what happens if it bogs down its running rich if it picks up its running lean

it may give you some idea of how its fueling

 

Sadly the modern Aerox bike has an automatic choke.

Hello,

I have some feedback. I've fitted a 70 main jet (as opposed to a 68) and the power problem has largely disappeared. When I pull back on the throttle, the bike accelarates in a smooth fashion. It does occasionally reoccur but it is an occasion rather than the norm. I suspect the real answer to this problem requires me to remove the carb, lift the needle a little, and try a 68 or 70 jet. But removing the carb is a difficult task (for a beginner) so I'll carry on commuting with a 70 jet for now.

I will try reverting to standard fuel (ie without 0.5% of oil) to see if that has any impact on the performance.

I continue to be perplexed to why the speedo won't display more than 50!

Thanks for all of your feedback and assistance.

How did you change the jet without removing the carb??

Lifting the needle is normally a pretty simple task. Often just remove the top of the carb where the throttle cable goes in and you can do it from there...

On the Aerox, you can get to the bottom of the carb by removing the air filter, ie.

1. Remove three or four screws on the fairing so it drops down, exposing the air filter.

2. Unclip air filter and undo two hex screws holding air filter to the bike frame.

3. With the air filter removed, the carb is now visible and the bottom (fuel/float resevoir) can be removed by undoing two screws. The float valve drops down so hold it closed with an elastic band.

4. Unscrew main jet that is now accessible.

I think the harder task is getting the carb out. The above didn't invovle removing all of the things connected to the carb, and that seems more of a "experienced" maintenance task than my "fiddling with bikes for beginners" method of changing the main jet.
