Does anyone have info re jetting of the Mikuni TMR40-36 flatslide carb when fitted to a stock Suzuki DRZ400S I bought my DRZ here in Cambodia and had the Carb and FMF muffler transfered from another bike. I am now opening up the airbox (3x3 hole) and adding an FMF Powerbomb header so expect I will need to rejet, bigger main jet at least. There's a few DRZ's running around Cambo with the TMR40-36 carbs but no one that I know of has any jetting info . tried Thumpertalk, no-ones heard of them I suspect there's a few DRZ's in Thailand with the TMR40-36 as well so would be interested to know what jetting others are running with hi flo aftermarket exhausts. My current setup is main jet 155 pilot jet 27.5 needle clip second from top. Stock header, FMF Q muffler recent 3"x3" hole cut in top of airbox (as per thumpertalk recommendation) With the opened up airbox and planned new FMF header, I suspect I will have to go 160 or 165 mj Comments, suggestions ??
