    I need Help For My race hawk

    I posted this in the MABE Racing forum. I need some guidence and Maybe some else knows about this stuff

    Day 1.

    Took My Race Hawk upto Loudon This week, Took it off the truck Rode it 75 Feet It died and Poured gas all over Me. Some SV racer guy Showed me how to check the bowls.

    Then Bike Would not start or run for more then 2 Minutes( Some old Vintage Guy Told me use to pit crew for a Hawk team in the early 90's and assured me my battery did not have enough Power to Start and run the Bike)

    Installed F4I Battery (not too Easy I may Add)

    Finished the day By Tossing My F4i Into the bowl at Full Throttle. Tucked the front when I first touched the lever, Not too use to the feel of the NEW master Cylinder I guess $150 Damage to the Bike a little sore no Biggie.

    Day 2

    Got the bike running Badly, Rode it up to Turn 1 Chris(stupidhawk) Took it for a test ride When he got back The stuff in the muffler Batting or whatever Was clogging the Muffler Like a turtle Head.

    Took the muffler apart It looked like a Sheep got sucked into the motor and Got stuck in the Muffler. The Core Rotted Out. Bruce Meyers Helped me sort that out. Open Megaphone style LOUD AS HELL, Still running Badly (SV guy comes over and tells me its my pilot jet) Go back to turn 1 Ask Yomit and Stupid Hawk About it Mitchell(yomit) Adjusted the Pilot jet and Idle.

    I got on the Bike For a test ride, It know has the Power, Bounce the throttle the front end Comes right up Power wheely No clutch (gearing 16/46)? WTF this thing is a Monster.

    Then we discover the Bike will not rev Past 5K Like some kind of rev Limiter (but not the rev Limiter according to the fellow hawk owners) So We Keep scewing around it Reving it Up With a Straight Pipe on it. LOUD (Hobbs Kids were Crying and Hiding under Cars Holding their little ears)

    Some say Main Jets Some say Electric.

    The track:

    I do some laps in the penguin practice, Still Cant get past 5K, The bike handles Amazing. its really light and stops Like nothing I ever rode before AMAZING. I am entering tunn 1 with more cornerspeed the in My Fastest Laps on the CBR. I pass an Rc51 and a few 600's between 1 And 2 Flying in the slow parts of track. THIS BIKE IS WEAPON.

    A lot of people are saying its the main jets? and i am like Where can I download the main jet map? So bruce Myers tells me to take it too the dyno guy. I Dyno Guy says come back tomorrow 8 AM.

    Day 3
    Dyno guy says no Sweat, Leave the bike I will jet it for you. I come back he says I am getting No fuel after 5K(not Running rich like if it was getting no spark) Told me the main jets and the Carbs Were gummed up sent me off to clean them.



    Erasmo and Mitchell, Dollar Bill And Myself Pulled the Bike into Hobb's trailer And Went Nascar on the Hawk. Cleaned the CARBS in 20 Minutes. Thew were Nasty My tank is Bad The gas looked like Snapple iced tea.

    Installed inline fuel Filter.

    Started the Bike Same thing nothing past 5K just bab bap bab bap.. I went crazy Its that Damm Tach Gauge Its gotta be, Trace the wire and Cut. Still Bab Bap bab Bap Same thing. Its that damm shift Light thing its gotta be Trace and cut Still Bab Bap bab Bap. I am pulling wires Touching wires together Praying to Lord Jesus Still Bab Bap bab Bap bab bap.

    Back to the Dyno Guy (he is a nece man patient man) They pull out the carb sync The stupid carbs wont sync (a little spring is broken) one Butterfly opens while another is closing he tells me, one cylinder is tring to speed up while another is tryning to slow Down?

    I gave Up. It seems I have so Many Little problems to sort out before I can even Fix the Big ones? I have an F3 Tank I can put on. I can buy any Part I need within reason.


    It seems my blackbox thing may some aftermarket Race type thing and and My coils are aftermarket Maybe thats my Problem? I will replace if needed.

      5k rings bells with me.
      Used to have quite the same problem on the highway:
      it wouldn´t pass 5k turns in 5 th gear.

      Pried into the carbs. Everything fine.
      Then took spark cables apart to find they were all rodden.
      Ditched the coils, cables and spark plugs.


      Resorted to new stuff - problem was gone

        I have been having a similar problem in regards to a drop in power, but it happens around 4.5k, then at 6.5k, then a blip at 8k, then I can pull all the way to the rev limiter. Just started happening out of the blue. I've replaced the s/p cables, did a full tear down on the carbs, pulled the harness, checked and cleaned all connections. I have a race this weekend so we'll see if any of that did it. Crossing fingers.

        Sounds like it might be a good idea for you to spend some QT with that bike, inspecting all the wiring, grounds, connections, etc, etc. I would also recommend getting that tank cleaned out. Speaking of which, when you pull your carbs again, there are 2 little filters that are hidden underneath where the float valves go. If your tank is dirty and your carbs were filthy, then there is a chance these could have gotten clogged up, restricting fuel from getting in the bowls.

          Hmmm,
          I know some people will rag on me for saying this but....
          I personally feel that the time and money spent taking your bike to see a decent Dyno and its operator is money WELL worth spending.

          My bike isn't yet running but as soon as I have it together again it will be off to a local guy I have heard good things about, helps he used to have a Hawk too.

          JD and the boys here can give you pretty decent guestimates for jetting etc. but there can be only one certain way to get it right.... Unless youve had years of experience in jetting bikes...

          Get it to a dyno!!

          Plus you get to see just how much (or little) the bike is making!

            Sorry Mongoose but there are so many things that it could be, I think it impossible to diagnose via electron exchange. Find a local talent and have the bike gone over top to bottom.

              It is funny you mentioned this. WHAT FILTERS Someone will be owing me parts for a carb.

              Filthy filthy filthy. Just looking at the carbs for now. Judging from what I found this will solve some of the problems.

              AND who the hell puts foam in a gas tank. No wonder why the gas looks like coffee and had all kinds of little bits floating around.

                @Mongoose - I will have to echo what Brewsy and Hord are saying. It could be one of anything or a combination of things and would be hard to accurately diagnose over ze net. A full top to bottom goin through seems to be what you are looking at.

                @nt650hawk - I never knew they existed until 3 weeks ago (thanks Hord). Check out this picture and you will see the valve seat and a little filter on the end of it. Just pull out the float valve and then pull out the valve seat with a 10mm socket, voila.

                  This is why I do not run a filter from the petcock to the carb. You already have one in the tank and the ones in the carb. Triple redundancy is better if you do not plan on performing a carb clean anytime soon. I will admit I have had mung in the carb filter where as if I had the 3 filter set up it most likely would have been caught. In Gooses case it's tank to carb.
