Default Carburetor needle help please. Raptor 660R

Yes I have dont tons of searching before asking these question.

I’ve been playing with my Raptor all day trying to get it to run 100%, no luck so far. I adjusted the valves at least 5x and had to re adjust the float levels. It still stumbles a little but instead of mid throttle it does it just a little now at the beginning. After adjusting my valves I still get a little valve tick. I followed the instructions to a T and re checked it many times. When I started there was 0 clearance. I set the intakes to 10mm and the Exhaust to 16mm. I adjusted, started it, rode it, let it cool and re adjusted many times but still get a little tick.

My main question is about the little clip with the O ring and spring that holds the needle in place and clips down in the 4 fingers that hold it in place. Does the O ring clip into place and that is all that hold it or does it push down further so the top outer ring clips into place down in the fingers? It seems awful loose if it is just the O ring that holds it in place.

i JUST found this out myself GOOD THING i took it apart twice you HAVE to push it into it just be sure to push up on the needle that way you can tell if you dident push down hard enough...its not cheap it wont break easy

So are you saying that it does not seat in the valve throtle by the O ring but you do have to push it in further so the hard plastic piece where you grab onto it with plyers actualy clicks down into the fingers of the valve throtle? Only problem is if it's pushed down that far the needle does not move at all, it bottoms out on top of the needle it seems.

well i ddient think abou tit that long but im guessing it does hold by the oring, but the needle will travel up the length of that small spring, youll know it will stay in if you push hard enough up on the needle

OK that is the way I though it was supposed to be. The needle should have a little travel up and down in the Valve Throttle. That is the whole point of changing the clips. I have been pushing it down to far because mine was not staying when I first did it, it would just pop out so I pushed down hard enough that the hard plastic piece at the top is what when down into the fingers into the slotted are but then I get no needle movement. I wonder why it ran so good most of the time? I was running to big of jets (175/180) but that is what it came with but I noticed it was to rich, way to rich so I jetted down to 165/170 and started getting the stumble. I'm not sure if mine will still seat buy the O ring, I doubt ti but we will see. Might have to get new valve throttles. [img]i/expressions/face-icon-small-sad.gif[/img]

i doubt if those things even need messed with in the first place, i wouldent know about doing it for mega mods but for me it did nothing except waste time
btw.. have you taken off that L&A ever? i was wondering about them if they stay in one piece but the gear goes instead of it? i took mine apart while in the tranny and the stock clutch was fine but the gear was pitted to hell and back

I just put the L&A one-way in last month. My gear looked like new so I didn't replace it. I bought a new one but compared them and re sold the new one. My stock one-way went out last month. Wasn’t to bad to change.

Well I will have to leave my needle and clip setup the wrong way since it runs right now but misses a little at the beginning of the throttle because I broke one of the fingers a couple weeks ago while pushing the clip down. No way will it stay in now just with the O ring, it barely stays in now being pushed in to far. [img]i/expressions/face-icon-small-sad.gif[/img]
