    extremely fast idle

    Thanks for the help. We did solve the problem by adjusting the jet needle up a notch. I guess this made the mix richer. worked great.

    extremely fast idle

    This is a 99 with factory carb. It may have been re jetted though.

    extremely fast idle

    As I previsly posted about my CR125; although my bike was running fine, i removed my carb to clean it. After i reinstalled the carb, the bike idled damgeriously fast. All rubber fasteners are secured and in the propper position. We noticed the pilot jet didn't have a spring and washer inside as shown in the manual- although the pilot jet looked very different than the one in the manual.We are thinking someone (previous owner?) may have re-jetted the carb. Is it possible the spring and washer are unnecessary with an after-market jet kit? We don't know what's causing the fast idol! Can someone help?
  4. Let it be said this is not my bike. I am posting for my son. He recently took off his carb and cleaned it out. He removed the main jet and the pilot jet then sprayed it down. After installing the carb and firing up the bike it immediately went to a screaming rate of rpm ( fast! ). He shut it down ,took out the carb again. After inspecting inside the carb and again firing up, the same happened. He said the jets were fully turned in when he first took the carb apart, so he put them back in the same amount of turns ( tight). Does anybody have any insights as to what may be going on?

    mffler wrap

    I put some new wrap on my muffler recently. It came in a unopened pack with my bike when I bought it. It was quite easy to do. When I took the bike for a ride I was immediately struck by the intense vibration. In fact, it instantly made me nauseous! I had to stand to ease the affect. I assume I need more wrap than I used. The wrap went around a little over one time. How thick should it be? Or how many wraps should I do. My muffler is a Dr.D 2003. I should mention that I had put on a new lowering link ( yamalink) previous to riding the bike. Could this be somehow related?

    Ignition system questions

    Glen, Yes, I am saying the bike had NO battery and ran good.as to the short I speak of. I did a leak test right from the manual.Disconnect negative from battery trminal and connect a meter set on 20vdc between the battery and the disconnected wire. There should be no voltage if every thing is off. I get 12vdc!! I left the battery connected over night and saw a 1 v drop in that time. So, yes it is losing voltage.

    Ignition system questions

    At the risk of embarassing myself, can any one tell me if my WR 450f ( 2003) has to have a battery to start and run properly? I bought the bike used without a battery. I have ridden the bike at least 25 hours with out one and then I suddenly had no spark after it sat for a month. I had thought my cdi was bad but it would not run with a new one installed. Now for the first time I put a battery in and it fires up fine. In fact the bike has more punch than ever. I also appear to have a major short. I get a full 12 v when I connect between the battery negative and the main ground wire with a meter without the bike running. I also have continuity between naerly any hot wire and black wires( and the frame). Let me say, the bike does not have a main on off switch, only a tethered kill switch and a push button kll switch. Do I need a main switch to cut the ower from the battery? The regulator is kicking back around 13.5 to the battery so that is not the issue. My stock head and tail light work fine when the bike is running, so that tells me the charging lighting coil is fine. The charging coil(stator) must be operating for the bike to run so well and it test good for specified resistance. Do I risk damaging anything if I use the bike? Some one heeelllpppp!!

    CDI and Yamalink from 2009 on 2003?

    Thanks for the input , and yes the link was to lower the rear. I will definately look in to your plan with the cardtridges. Thanks
  10. Wondering if any one knows if a 2009 CDI will work in my 2003? How about a 2009 Yamalink. This is used for lowering the front suspension. Cant tell by looking on manufactures page if the diffent yars are interchangable.

    rebuilding cr125 forks

    i have a 99 cr125, my forks where leaking so i started to rebuild them, i am at the point where i separate the two fork tubes and, as my manual says i i tried to pull/yank them apart. my dad and i spent an hour trying to pull them apart but we didnt move them more then 1/2 an inch. does anyone have any idea whats stopping them from coming apart? i want to ride and srings almost here so any advice would be awesome. thanks, tobias

    Ignition problems wr450f

    Thanks for that bit of info. I was unclear which polarity to set my meter to. The readings I got were on DC, but not very defined since they change so fast when I kick the motor over. I welcome more imput from others.

    Ignition problems wr450f

    I am still trying to discover why I have no spark on my wr 450f. None of my resistance testing seems to point to any bad devices. So now I am looking for power from the engine. I am using my meter on volts ac and checking for power when I kick the engine over. So far I get nothing at the two wires that lead to the coil pack on top of my plug.I do how ever get a small reading of around 3VAC at my alternator/stator coils.Nothing at the pulse generator but I dont know if I should be getting anything here. This leads me to suspect my CDI because I believe the power from the stator runs through my CDI before it gets to my coil pack. I have checked for continuity allover the place and found no problems with any of the wiring connections. If any one has some advice or insight it would very much be appreciated. I have unanswered questions on my previous post about some this stuff if any one feels like reading it.

  14. I have a wr450f that has no spark. I have been running some tests on the ignition system,but my question is this. Should the coil (that sits directly over the plug)have continuity betwen either of the two connectors on top and the bottom connector that attaches to the top of the spark plug? I have none. It would seem the current would have to travel a path to the plug (continuity) unless it jumps somehow inside the coil ( no continuity). Any help would be appreciated.
