Throttle stuck (handlebar not twisting at all)
December 28, 2009 at 12:50 am #3629AzN LogiKParticipant
So i just started up my Ninja 500 for the first time in like 8 months and it started up just fine, warmed up fine with the choke, but my problem now is that the throttle isn’t turning at all. the handlebar is like stuck and i have no idea what the problem is. i’m guessing i’ll have to take that thing apart. everything else looks okay except the gears aren’t shifting smoothly like before, but they still work. The chain needs to be tightened and the whole bike just needs to be maintenanced.
The throttle isn’t tight, it’ll move like a millimeter or so pretty smoothly but it won’t engage the throttle (talking about the handlebar throttle control). Beyond that, it just doesn’t move, but instead the whole handlebar assembly (the box it’s connected to with the front brake lever) will move a little. anyone got any ideas of what’s goin on?December 28, 2009 at 4:10 am #23833MunchParticipant
might need to have some one take off and lube or replace it for ya.December 28, 2009 at 5:12 am #23834briderdtParticipant
Cables kinked, corroded, or just plain stuck?December 28, 2009 at 7:42 am #23835eternal05Participant
If the grip won’t twist past a certain point, that suggests the throttle cables are holding it back. If you can, buy or download your bike’s service manual. I’d check along the length of the decelerator/accelerator cables, and especially at their carb-side end. You may need to take some fairings off to see there…not sure what the fairing gig is with the 500R.December 29, 2009 at 8:31 am #23844AzN LogiKParticipant
thx for the suggestions. the last time i checked it was twisting just fine back in the summer but it’s sat outside covered since then. probably corrosion now you mention it, but probably not kinked cables since the bike hasn’t moved.December 29, 2009 at 7:49 pm #23847BouncingRadicalParticipant
If the throttle is frozen, taking it off the handle bars is pretty simple. If it has sat covered for a while, something might have made it’s home in the space between the throttle and the handle bars and crudded it up. While the throttle is off pull the push and pull cables and observe how they act down at the carb. Squirting a little WD-40 down the sleeve at both ends and working the line would help alleviate problems in the sleeve, if there are any. My bet is the throttle is seized and a disassembly and cleaning would help out your situation a good bit.
If it’s anything like mine (Kawasaki KLX250), the hardest part is keeping the pull cable in place when putting it back together. Just remain patient and it will go smoothly. I know the ninja 250 has the same carb setup as mine.
Good luck, and if you don’t feel confident doing it yourself take it to a shop.December 30, 2009 at 3:10 am #23849IBA270Participant
Make sure your throttle plates will open. It may not be the cables at all, but the butterflies sticking.January 26, 2016 at 8:04 pm #30022AkiraGuest
