#1 PostAuthor: stephen parr » Fri Dec 14, 2018 6:45 pm

Hi all, not been on for a while.
Does anyone on here know the basic setup for the above carbs please?
Need to know jet sizes & needle type with a standard 1015 motor.
Thankyou

From greg copes ape tuning guide.

For those of you running 29 smoothbores on a mildly modified street machine, here are some suggestions for carb modifications to give better mid-range performance:
# 20 Pilot Jets

# 0-4 Needle Jet

# 1.0 Air Jets

# 2.5 Needle & Set

* Float level heights, base of gasket to top of float 23.5 - 24.5mm
