    I should have found all the required specs for the carbs, will have a go shortly, thanks guys I agree with all the comments Ive been wishing that the carbs were done during the rebuild but it looks less and less likely.

    Will stick with the current setup as far as intake and premix go but making sure its tuned as good as I can get for that setup.

    Wouldnt mind an air box but may be a too greater hasstle.

    Cheers

    Can anyone reccomend a place in hamilton to get advice on correct jet sizes and if it comes to it repair?

    Someone has butchered the carbs the majority of the screws are rounded off and even the jets have had the heads miss-shapen from incorect tool use.

    looks as tho when the engine was rebuilt the only work to the carb was a clean, its very clean inside but the jets are still origional.

    Hint for searches....
    Search NSR*
    That way it doesn't matter if there is a space or a number after the R.

    Ok Im a bit behind at the moment but thanks to the bloke on tm selling mc18 parts I have now sourced a chain guard, muffler bracket and radiator reserve (my radiator reserve was accidently binned due to leaving it at the paint shop) I will be leaving the bike as it is running on premix and free flowing intake.

    The new plan is to take the carbs to mdlracing and have a base jetting done to set the bike up for premix, free flow intake and to tune it for commuitung, lets hope I can sort this before the parts come up from chch.

    Many of you will disagree with this but I plan to go back to a cage untill I have corrective sergary on one eye and have got my full class 6, so I will be selling the nsr once it is going and wont replace it untill I have my full.
    Any interest in the bike gimmie a pm.

    i don't disagree with you leaving as is, i was just stating it had to be setup to run how it was,
    there probably won't be much in the price difference between getting it set up correctly and buying the airbox and pump,

    fair do's though,
    keep us posted
