2200ft elevation 20c (70f)

I have 2200f 52p for the most part it gets rid of the quick throttle bog.

Have a buddy with the GYTR setup (68p/70pj/y4-3rd/165m)in his bike and he rode mine with oem(72p/35pj/NYDF -1/165m) noticed the slight burble but commented roll on from closed throttle significantly better quicker response -rest same ish. He’s thinking of trying a 70p. Then maybe see if the 70pj is really necessary and go back to the 35pj. We are confused if...

I’m going to quit over thinking it and just go with a needle with a bigger straight section if the burble is a problem. I would say if the stock jetting burble bugs you then the Y4 and 2026 getting is going to seem better but I think the lean pilot and straight portion hurt torque out of the hole...

No I would say rich. I don’t know the difference in the needles but believe the 95 power jet is the issue. The 2022-25 jetting cleaned up every thing minus the 0-1/8(maybe 1/4) throttle position but I never really noticed the rich pilot/needle straight portion.

This also so happens to be the mxa setting.

I got to try this jetting in race situation and while it’s good, with tacky ground and up hills right out of corners it lacked the cleanness /torque I was used to at this particular track. I had race there earlier in the year with the GYTR Y4 needle setup also and it was lacking a bit in a few...

Second ride with the 2026 jetting. A bit cooler 23c but results the same. Think this jetting is staying in the bike. Bike does not get rich feeling 15min into moto like the Y4 setting seemed to a little.

Ok 2024 yz125 - new crank /new top end. Only thing not OEM is wossner crank (good luck finding oem) and boyesen rad valve. So my review: 2200ft 27c (80f) - dry hardpack -testing against pro circuit Y4 suggested setting.(from memory 2weeks ago same track conditions but a bit cooler 24c) 65p air screw 2 1/2 out (tried 1 3/8...

I found the same thing. Was running a 65p 1.25 and got a bog on seat bounce jumps that required really quick blip of the throttle.Went to the 68p and it stopped the bog unless I tried going out further on air screw then it bog again. I bet a 70p may be the sweet spot that would allow the...
