I have 2007 LX 125, ZAPM44100, carb, with Malossi 187cc kit.
There is a lot of info on this forum, I did the same research before I got my LX with carb. I would like to thank all people here for sharing
What I found, basically boils down to two main points:
- if you don't have time/don't want to play with your scooter you should get the IE version. There is nothing you can do without a proper cable and software or going to service.
- but if you like to play with your scooter, set the idle rpm with a screwdriver, swap idle jet to test how it will improve acceleration, sometimes clean the carb without the reason (me!) or you may upgrade to 187cc kit, you take the carb version.
The IE will be more efficient and probably smoother, but Im happy with my carb (upgraded to 27 from 26.5). I was missing this old school tweaks, playing with my tools and feeling after something works better after I fix it myself
In my last 3.5k kilometers I had never any problem with LX carb, all issues I had were my mistakes, like not clamping vacuum hose to the fuel tank valve and loosing fuel supply, spark plug cap becoming loose. I'm using only super fuel (97-99) so I'm thinking this fuel and new little fuel filter is keeping my carb clean.
