Also wondering what kind of cranking pressure do you have?

[cxman]

pilots 35 may need a 32.5

no air correct jet to start

2.5 slide

q0 needle jet

6dh4 needle 3rd or so groove to start you may need to go down a size depending on your bike

use a 135-140 main to start

I like that needle and jet combo.  Much leaner off idle and similar at 3/4 open up.

Ok i'll try your suggestion for needle and needle jet, thanks.
Bit curious about the main jet size though, pretty much everyone else is around the 260ish size?
My slides are 2.5's
Not sure what the air correct jet is?

[cxman]

are you running a single carb?

or twin carbs


a air correct jet goes in the small hole in the intake side at the 6 oclock position

Twin carbs

[jimmer]

I really like my single flatslide setup! Now back to our regularily scheduled program.........

[cxman]

i have no idea why you would run a 260 main on a twin carb setup

i dont have anything that big in any of my jetting notes on that bike

i think that flat slide is great thats a 36mm isnt it

i just saw where on f the gp racing guys back in 2008 said he was running 260s but on a gp motor with chambers

seems awful big to me for the street and may simply be that the motor cant approach the draw limit on the jet i dont know

or he was not running pump gas

I am surprised how small a main jet is being suggested. Race GT500 carbs I have cleaned have had 230/240 and 260 mains according to my notes.  Interestingly a TD3 or early Tz is typically 280-320, albeit they rev a little higher and are in a higher state of tune. 

That suggests that even in a relatively low state of tune, a T500 pulls in so much more air that it creates a stronger signal over the jets.

38mm on a GT750 runs 280-340.  I have seen 210s in 32mm carbs on a 750. Nothing as small as 135.

You have more experience with them than I do, but those are surprising small numbers.  It will be interesting to see what John's bike wants.

you are probably right the notes i have are from 1977 and my memories from there are almost as fuzzy

its probably a mix up in recording the main
