woodro77 Posted March 28, 2007 Report Share Posted March 28, 2007 i have a new motor , slight porting , nothing crazy , v-force ,+4 timing , toomey t-5 , got pwk oko's , 30mm and trying to get them dialed in , they were shipped to me with 155 main 55 pilot, needle in the middle ,it was cold , 25-30 degrees out , it ran great , got alittle warmer out and i got a bog just after idle , higher rpm's it was fine , i dropped the main to 152 and 52 pilot . when the motor was cold it ran mint, no bog and pulled hard , after a couple minutes when the motor got up to full temp it started to bog and hesitate , higher rpm's were fine . called the place i got them from ,CPW and he said go up 1 notch on the needle (leaner ) that made it worst , so i went 1 notch towards the pointy end and it got a little better , went to the last notch closest to the pointy end ( richest ) and it was better but still had a hesitation , CPW told me to try the the bigger jets , so i did that and tried all the clips spots and it was bogging and poping bad . so i called them back and they said they would send me a different needle and to try that . does a needle mean that much ? have you ever had the wrong needle mess jetting up that bad ? he said they have sold hundreds of sets of these carbs and never heard a problem like this .

fastrthnu Posted March 28, 2007 Report Share Posted March 28, 2007 yes , but i cant get it right with any of the clip positions maybe its just the taper then. Thats the only other thing I could think. from 1/8-3/4 is going to depend on taper and position. Quote Link to comment Share on other sites More sharing options...

wesw Posted March 29, 2007 Report Share Posted March 29, 2007 does a needle mean that much ?have you ever had the wrong needle mess jetting up that bad Wait till you get some pwk or pj carbs. needles can make a shit load of difference. sounds like your bike is thristy in the mid. those needles are hard to cross reference against. so best of luck.
