You shouldn't have to restrictions only happen on faster bikes 600cc onwards but if you talking about the inabilty to push your revs to the very max, I wouldn't do this unless you know what you doing, and by you asking this question, you don't know what u doing, this rev restriction is set in place for safety of your engine, rather than restricting speed.,,,

You can download the service manual for nix from here. trying to picture what you are looking at, but if they are the only rubber hoses coming off the carby, then they are most probably the fuel lines. If they come off the very top of the carby, then they may be breathers. The bike has a vacuum operated petcock also, you will need to have it in prime position for the carbs to fill. Then once the engine runs, if the petcock os working correctly, then you should be able to get fuel in on position. Just cranking it over will not created enough vacuum for the carbies to fill.,hence the prime setting. Happy to answer any questions you may have about the bike, A FixYa rating is a great reward for my efforts to assist you. Cheers

Turn both screws inward and seat them GENTLY. Now turn both screws one and one half turns outward. This is the factory setting.
Please rate this solution as a "FixYa" Thanks!

Yes, the float or the float needle is sticking in an open position. The only other possibility is a float that has a pinhole in it and has filled with petrol and will no longer float as it should.
