Greetings everyone!

I have a problem with my ER6n that I hope some of you more technically adept people might be able to help me with

Recently, I had a minor fall off my bike, but apart from cosmetic damage (and bent handlebars) nothing felt out of the ordinary.

However, from a couple of days after the accident, some problems with the throttle position sensor (I think) started to show up.

At startup, the revs oscillate fairly quickly between say 800 and 1200 (maybe once per half second, the revs will go from 800 to 1200). However, when I'm riding, a twist of the throttle at low RPM will give me no power at all, only to come all at once at some unpredictable moment (and it may cut out again, and rise again without warning before 5000RPM). At high RPM (about 6000RPM) the problem disappears. Also, on some occasions, opening the throttle from a stand-still will stall the engine.

Now, I've mentioned that I think its the throttle position sensor, however I'm not sure. I'd like to know more qualified people's opinions, and perhaps some help in fixing it

I've also posted this same post on KawiForums, and maybe a few others if I find them later.

Cheers!

 

Another possibility: the throttle body is not synchronized. Possibly loosened/jarred on the fall. That is easy enough to check.
