Re: Flatside carbs
No real problem which the right tools .
Have you tuned motorcycle carbs previously?
If so ;
For starters you need a carb synch gauge. These are about $130.00-150.00 plus shipping ex USA on fleabay. Will also work on your 10 if needs be.
>Base setting on carb slides is about 4mm between slide/venturi(drill bit works fine) set all to this as accurately as possible starting from the centre two .
>Base setting on the airbleed screw is about 2.5 turns from LIGHTLY seated on ALL.
>All float levels must be exact. (as in millimetre perfect with the carbs tilted so the tab JUST touches)
If not ;
You need to find someone who can / or you will need to do quite a bit of homework before attempting yourself.
Alternatively offer a carton or two of icy cold beverage to a local kind hearted (thirsty) KRSCian bike guru
>>>Yes they are a bit less forgiving in the tune department than the CVK's but the end result of well tuned pumpers on a 9??? Woohooo
