750 small pin
Advanced timing plate
Ports dropped 4mm and polished
Bored to 81mm
Stock compression (160ish haven’t checked in a while)
Dual cooling head
Factory pipe Ltd matched manifold
14/19 impeller solas
Intake scoop
Extended ride plate
Just put dual SBN 46s on a week ago. They came reverse jetted and they bottom was wayyy to rich and the top was too lean. Rejetted with 110 low 135 high 2.5 needle. Pop off at 20psi with shiny silver spring.
Can’t seem to get tuning right here. Tried dropping the pop off a little and it gave me good bottom end but killed my top end. Raised it back to 20 then had to richen the bottom like crazy or it wouldn’t run and now it seems to have a lean hesitation even with screws out like 1-1/2 turns.
Doesn’t seem to really hit like it should and tops out way too early.
Was thinking I may need to adjust my pipe too as it isn’t getting very hot. You can hold your hand on the head pipe for a short moment right after wot. Too cold.
Any advice would help
