I think ATP-205 and Blue Devil is about $20.00 here is USA. ATP-205 not on shelf around me so have to buy online. What I can say is they do what they say

Should I go with the cruzinimage jet needle (is it close enough to the DP2)?
Should I use jet needle position 3 with the 115 mains?
jabcb.
Contact Paul Miller. Give him the part# of the later needle. He may have. I know about the later setup much better. Or see if he has the DP2.
I use clip 3 not clip 4 on the later t350 setup. 110 or 107.5 main is better than 112.5 IMO.
Well to your questions.
If the OEM needles are not worn ( use magnifying glass to prove this to yourself) just stained use the OEM needle.
If not, I would trust Keyster's needle over cruzin, but since you have an OEM needle you can check for yourself (not easy I know unless you have a comparator instrument or something).
I would go swith tock setup to start. I would
not go up on main jet. If me I may use clip 3 to start but not clip 4 but I am biased and helps prove a test I'll explain next. Seams like stock is best place to start, but you may have to adjust if you are fussy about getting it perfect everywhere.
One way to know if it's too rich on main is run engine WOT and very very quickly snap it back to smaller throttle opening. If the engine gurgles for a moment and then cleans up it was too rich (of course what you snap back too is too rich as well then this wont work). This test works well!
As far as clip position go for a steady ride that uses the needle circuit only. Not a ride where you are trying to hyper mileage, just try to stick to running off needle jet circuit. You should get low 40 MPG (40 - 44). If less than 40 MPG (e.g 35 -37) move clip from 4 to 3.
With 0.7 secondary jet 35 pilot is a little too much (run air screw 2 to 2.5 turns out OK). If 32.5 pilot a little too lean but run air screw 1.25 to 1 turn out ok.
If the day is 90 F and humid versus 68F and dry you know the difference in not tuned very center to start.
You can get those T350 carbs tuned so the work very nice with T350 everywhere in the throttle range.
Also the bike likes stock timing if not a little more advance for stronger 3500-6500 RPM. And OK to rev past that for a moment (like a quick 0 to 60/70 mph pull) without worries. If the timing drifts a couple degrees retarted you will note the lack on this mid-range power.
with diesel and fill gear oil to the max. If needed I lift rear end of bike This will ensure the seals are sitting in highly concentrated mix. You can also fill the piston sides and drain via crankcase screws after.
