2017 SM how to check if carb has been jetted

Recommended Posts

Good evening everyone I bought this 2017 DRZ400sm at the beginning of august and it has a full yoshi system on it. Now you have to understand this is the first bike I've ever had with a full exhaust with a carb so I know little to nothing about it so I guess my question is how to check or tell if the carb has been jetted. Im really wanting to learn how to work on bikes because I have always loved them when no one around me does so I've never had anyone help me where to even start any and all help is much appreciated!

Pull off the seat, see if the airbox has a big hole under the ignition module.

A 3x3 has nothing to do with jetting....

Pull off the carb and pop it open. Tons of videos on youtube.

Takes about 15 minutes

Yep. Could have been jetted without opening up the air box. Only real way to know is to physically look at the numbers on the jets.

Once I get my jetting to where I know that’s how it’s going to stay I plan on making some notes on the inside of the air filter cover to benefit anyone (myself included) going forward.

The JD Jetting kit comes with allen bolts to replace the float bowl screws, that is external clue #1.

Clue #2 is if the brass plug covering fuel screw has been removed.

Clue #3 is put the bike in gear around idle speed and try to power wheelie. If the bike doesn't pick the tire off the ground then it is likely stock. If it has the power to flip over it is likely jetted. Gearing changes could influence results.

The screws look a bit beat and it has a adjustable fuel screw. Most likely it's been jetted but the only way to know for sure is check the sizes as mentioned above.

The adjustable fuel screw is the round knurled one.

It should wheelie in 1st atleast if it is jetted correctly and the 3x3 mod is done.

i cant wheelie all that well but she wasnt super about it when i wrenched on the throttle
