New rider help
4 Attachment(s)
Hi, I’m a new rider and having mechanical issues with my enduro 250cc but don’t know what. I’ll start by saying it’ was brand new buying it , and I’d ride it about 20-30 miles on it 5 days a week. After a couple months in, I was coming off a stop sign and switching gears was fine until I put it in 4th, then suddenly the bike started bogging down and sputtering. It would then die shortly after. Sometime I can get it to turn back on but if it does it shuts back off or won’t have full power when giving it gas. It has moments where it runs fine for a bit but will not stay well and 100% all day. It’s fuel injected so no carb. Oil was at good level and spark plug still good. There is this thing that looks like a sensor that broke, not sure if that’s related to the problem, I attached pics. And I don’t know what kind of sensor it is. Any help is appreciated . Thanks in advance! :thanks::

That actually looks like the rear brake light switch, but you may have a wire shorted because of it.

I am going to go with Bill Hilly’s idea also.
My main power line on the bike chafed through at one time and it behaves exactly like you are describing. I think it’s an electrical problem. They are not fun to find. |
I’ll check the wires, but last I checked that sensor isn’t connected to anything else. Also I want to add that sometimes while riding I’ll get the loud popping from the exhaust . So it isn’t a fuel issue?

Forget the complications and go to the basics.
Fuel Air Spark Youu know you have spark because it will start and run sporadically. With EFI you have two other checks, fuel and air/fuel mapping. You are totally dependent on an electric fuel pump to keep moving so check to see if you have proper fuel pressure, your pump is working, and that your fuel filter is not blocked. Check for free flow through your air box. After that check your CDI. Electrical shorts usually do not cause bogging throttle and popping exhaust. Bad mapping and twitchy fuel pumps do. |
What bike is this actually on? That would help. More than likely that is some type of vacuum line. You need to locate where that was actually tied into. You could try temporarily plug I to see if it makes a difference in how it runs. Having just a picture of the broken part doesn't tell us what the other end of the hose is hooked to. In order to diagnose the problem we need the full picture of what we are working with. The more information you can provide the easier it will be to help.
