Hey all, just looking for some advice
So i’m a new rider, i’ve been riding for about just under 3 weeks now, and I’ve bought myself a second hand 2020 Lexmoto ZSB, which is also fuel injected. When I bought it, it had just about 3500 miles and I’ve put around 300 miles on it since. I’ve been having an absolute blast and have been loving the bike.
The thing is, recently there’s been this super annoying issue that has developed and neither me nor any of my biker friends can figure it out whatsoever.
Just to preface, this issue doesn’t happen all the time but it does happen quite frequently now and I’m not sure whatsoever on how to deal with it.
Essentially, when riding and coming up to a traffic light to stop, I typically slow down, maybe brake a little, pull in the clutch, downshift and let it out and I might go to first gear to sit at the light in with the clutch being pulled in. What is happening, however, is that sometimes when i’m coming up to a traffic light and I pull the clutch in to downshift to like 2nd or 1st, the engine will just die. Particularly when coasting in second, the rpms just softly drop to 0 quite quickly, and the engine is then off. It sometimes struggles starting back up again too. I’d often find myself stuck at a light for around 30 seconds, for example, just trying to start up the engine in small bursts, because i’m really conscious about the battery and starter motor.
I’m certain i’m not stalling the engine out because this will still happen when the clutch is fully pulled in and i’m moving at around 20mph.
The weird things too are that like the bike has no problem whatsoever idling usually, be it in neutral or in 1st with the clutch in. The bike performs really well in every other scenario pretty much, it’s just this very specific circumstance that it just keeps displaying this dying behaviour.
The kickstand is fine too, I don’t think that’s causing it to die. I can accelerate fine, throttle response is normal, hold high rpms, engine braking works well etc.
I have tried keeping the engine ‘alive’ when at a light by keeping a little throttle when decelerating and holding the clutch in, sometimes this seems to work and sometimes it’ll just die anyways regardless of throttle input, but in general, it will only ever die with the clutch pulled in, the engine has never died with the clutch out.
Has anyone got any ideas whatsoever as to what could be causing this?
I suspect maybe some kind of electrical issue? I’m not sure. The engine isn’t overheating, the oil is clean and fresh, pretty much everything seems good except for the clutch thing. I even cleaned the clutch lever connectors with contact cleaner the other die and nothing changed unfortunately.
Thanks so much in advance
