kipaCarbuertor for 520 525 400 540 RFS EXC SX Suzuki DRZ400 GRSXR750 GSXR 1100 CRF450 Dirt bike, Replace for FCR 39 Flat Side Carburetor 39mm, OEM # 59031001300

It's a knock off but it works well enough.

I knew mounting this to my bike would take a little work and thought, but thanks to Motocheez, I knew what I was in for. The power increase was more-than-noticable over the stock BSR36, even with the JD Jet kit installed. The carb also come complete with a wide assortment of main and pilot jets, and as a bonus, also has the adjustable Pilot Air Jet/Screw, that is easily accessible with a long, thin screw driver under the red intake bell. The stock throttle cables can also be used. I also opted to move both upper motor mounts to the left side of the engine for a little more working space.My only complaint and the reason for four stars is it's more finicky to tune than the stock BSR36, plus an annoying hanging idle that I'm having a heck of a time tuning out. I'm about 80% there and have confirmed multiple times, no intake air leaks.

The carburetor is not pictured with a choke, but mine came with one installed, which was pleasing. I bought this carb after watching a motocheese video. Buy on my install I took it a step further and purchased the correct vacuum port for the pet cock and the correct air box adapter. You’ll need an iron gas well for the air box adapter. Another purchase I made was an extended fuel/air screw for an fcr carb, but unfortunately it doesn’t fit. It interferes with the large cap on the bottom of the float bowl.

Dont open the throttle when u open the box unless u want gas squirted on u. Didnt think it would have gas in it. Looks new. No marks to assume it had been installed before. Also, no slow jets provided in my box only the mains.

Well made. Installed on a 02 XR650L. Had to bore the intake boot to 52mm. Still fine tuning the jetting.
