Jetting help again if you all would be so kind.
1985 atc 250r. Just rebuilt my top end with a 68.50 big bore, port and polish from bdt motorsports. And a Boysen reed block. Stayed with pump gas didnt want to deal with race fuel. I have a fatty fmf exhaust (probably needs new packing) . Stock carb bored to 36mm. (I have plans for a 38 or 39 mm but cant afford atm). I have a nology spark plug hotwire and dont know if it matters a wiseco billet clutch basket. I would like to run stock box and lid due to mostly dune riding. Uni air filter.
Elevation is about 3000ft
Temp for winter 30f to 80f
Summer 50f-115f
Current main jet is a 180( bdt recommended 170-172. 180 was on hand).
Pilot is 52
Airscrew 1.5 turns out.
Stock need 4th clip from top
Can't get past 1/3 throttle before bogs and loses powerband. Any advice would be greatly appreciated.
Currently going through break in process.
