I have an 05 bf750 and I installed a dyna cdi ,it works very well for the most part but I have developed a low speed miss when driving at 35 kmh/20mph. I called dyna and they suggested raising the needles. I tried .035 shims it's better but still misses at low speeds, if you accelerate hard from a stop or if you nail it from 50 kmh it works fine. Would a dyno jet kit help?

 

Does yours have the new front needle that eh 05 were recalled/tech bullitine for

 

yes i have the front needle update done
