38's on 1127

[Blue]

Factory pro have some examples of different setups using the 38's what have you fitted? 

Main jet? Pilot jet? Needle position? Filters? Any Slide holes filled? Thanks

I have a powerscreen engine with standard 4-2 exhaust from an 1100L, carbs and airbox from a 750L. K&N filter in the airbox, 142,5 main jets in the otherwise stock carbs. 3 degrees ignition advance.

Runs quite well, pulls all along the rev range.

Thanks cc, I thought there was more people using these! I'm gonna start with 150 mains, 35 pilots, 2nd clip on needle

I'm probably the only one in the universe to use a standard exhaust system. Less restrictive 4-1 needs bigger jets of course.

b12 with 89 gsxr cams. 2 brothers midpipe and muff, and 38mm 750L/M/N carbs. factory pro crb-s21 kit (made for exactly this application)

ram air filters stretched over bandit airbox "stacks". I have yet to try the staggered length 750 ones. or perhaps order another set to experiment with shorter or longer... 

37.5 pilots (out of my old bandit carbs) 

150 mains clip in the second position from top with one shim (almost middle slot, backed off just a bit for fuel mileage basically)

one slide hole filled on each slide.

pulls like a freight train. Sounds just a hair on the lean side up top. I'm thinking the final touch is exactly this setting but with 155 main. Literally just to make my ears happy.
