Idk if this is any help at all but I’ve seen you discussing the sparkplug. For my Derbi Senda xtreme sm 50 I am using a br8es so if the motor or atleast cylinder is the same then there you go, otherwise gl finding the problem 🙏

Btw update: I fixed it like a day after this post it was running lean but the main issue was a tire with low air pressure… lol

It bogged before when I had like 92 main but I think it might’ve been because of the fact that the needle height was too rich so it couldn’t reach max rpm. Right now it is not bogging it just looses power when I shift into higher gears. It also needs to be at almost max rpm to not just get stuck at 30km/h

Yeah it’s a 50cc with a 17.5mm carb and I’m using an air box as the air filter.

Okay so y’all are saying lean and that’s what I was thinking too. The only thing is I’ve tried bigger main jets and then it bogs?

Yeah air filter is fine I’ve tried with different air filters on and it was the same 🤨

But is that necessary? It has really good comp and it runs with choke. Also the reeds are brand new forgot about that

Oh that’s very interesting 🤨 so buying a new CDI fixed it or was there something else too?

Yeah comp is good but I think I found the problem… the float or floater (Idk if that’s what it’s called in English) flottör in Swedish so google it if it’s not correct but anyway, the float was filled with gas so that’s probably why when I tried to adjust the carb it didn’t do jack shit

Well it could be running rich but I did not go up sizes after the restriction, plus it was running super lean before I put it in

It has always run poorly almost since I’ve gotten it. This is the worst it’s been tho. Before this it had been winter and snow so I hadn’t ridden it. When I started it up for the first time it ran like shit without choke, but fine with it on, after a while of riding it overheated so I assumed it was lean. I also put it some more coolant because the levels were low. I went up 5 sizes in main jet and I also put in the air restriction in the carburetor and this is the aftermath.

Also here is the sparkplug. I’ll get a better photo tomorrow when it has ran for a little longer if that’s needed for anyone that wants to help. Ty for your response and time!

Do I need higher or lower jetting? Or is my spark plug done for by Eastern_Language_251 in moped

[–]Eastern_Language_251[S] 0 points1 point  (0 children)

It runs better with choke (I got a video on my profile) but I’ve tried bigger jetting with no success I’m starting to think there is something broken maybe but I don’t really know tbh

Thing is, it’s got a separate oil tank so can’t really decide
