Benny,
These carbs come one at a time. You may be thinking of the FCR39s, they are available in single, dual or triple setups.
I need to go back to the dealer (third trip today) for some way smaller pilot jets. There are 50s in there now and Ed is using 30s. I am gonna get some 35s and start from there. The main jets were friggin 280s!!! Yowser, I backed them down to 150s to start with.
Oh, and Jane came home with a box of Jaffa cakes for me to nibble on whilst tweaking, and of course it is now pouring rain, but that's okay, wash them roads Mama Nature!
edit: Ok, after extensive research (google is my friend) I am gonna try #20 pilots instead, that seems to be one step higher then what the 400cc thumper guys are running, in my odd logical mind that seems to be close. He11, what do I know.
