Need jetting help 2005 crf 450 carb on a 05 trx 450. stumbles when stabbing throttle

[Ryanlong811]

Okay so I just put a 05 crf 450r flatslide carb on my 05 trx450r. I have it jetted pretty good except i havent messed with the leak jet. i have a 175 main. a 48 pilot. and a 70 leak jet. it stumbles (bogs) whe you stab the throttle from idle. From what i read im guessing i need a smaller leak jet. What do you guys think. Thanks!

Try a 35 or 40 leak.

I had this issue and soldered mine shut.. I may look into a QS3 though

I use the QS3 set roughly at a 40 leak jet. 168 main. 48 pilot. Full exhaust and no lid on an 05 crf carb.
