DRZ400sm jetting comfirm

Recommended Posts

My jetting is :

FCR39 - old style

162 main jet

200 main air jet

EMN needle clip 3

45 pilot jet

90 pilot air jet

2 turns fuel screw

No taffy mod

Bike also has 3x3 mod , twin air filter , FMF HiFlo header + Akra slip on with the baffle on , am at sea level , is this a little rich or is my idea ?

Should i change to 155 main and 100 pilot air ( if i find any...) ?

Any help would be great !

P.S I can't do a dyno run cause i still saving money for the big bore...

Does look a little rich. Do the main jet test:

Starting with the recommended main, remove the airbox door and go for a ride (bike fully warmed up). Is it better or worse?

If it is better, you need a smaller main.

Go down one size, replace the airbox door, ride. Remove the airbox door and test again. Better or worse? If better, go down a size again. Keep repeating this till the test with the airbox door is worse.

If it was worse with the airbox door removed, tape over 1/3 of your 3X3, test.

If it is worse now with the tape and was worse with the airbox door off, your main is just right. You are done!

If it seems better, you need to go up a size in main jet. Test it again (remove the tape). Replace the tape, test again. If with the tape on it is better, go up another size in main. Keep repeating this till having the tape on is worse than with it off.

To finish up and ensure you are set accurately, retest the bike with the tape off, ride it, then remove the airbox door. Best performance should be with the airbox untapped, airbox door on.

Remember, the main only operates at WOT. Ideally, you want to be in 3rd or 4th gear doing the tests, hitting max revs (just shy of the limiter) for at least 10 seconds to get an accurate representation of the jet status.

My guess is a 158 will be what you settle on.
