Blaster Yama 1100 jetting?

[Quinc]

Anyone know what stock jetting is for a raider 1100?

Also any recommendations for a blaster ported 1100 (yamanube template)
-raised compression 150psi
-removed half the screens from the airbox
-mikuni 38s
-No pipe mods

Leaning toward:
-110 Mains
-75 Pilots
-changing seat from a 1.2 to a 1.5
-keeping the stock spring

Rebuilt the carbs today and stock where:

Carb 1 and 3
107.5 main
67.5 pilot
55psi pop off 1.2 and 80gr spring

Carb 2 (middle carb)
95 main
67.5 pilot
55psi

We switched out the seat and springs for 43psi pop off on all the carbs.

Still leaning toward either 110 or 115 mains and 75 pilots. Or will that be too rich?

I left the jetting stock but removed the choke plates and put in a primer kit and T handle Jetworks screws.
After opening the high and low speed settings richer, it runs perfect.
