    Honda CR125R (1999)


    I LOVE my CR
  14. I got a 02 honda cr250r with full pro circuit exhaust system, boyesen dual stage power reeds, and twin air filter, am running maxima premix 32:1. Before I replaced the reeds it had a hard time idling and trying to get warmed up it always bogged. So i was told to replace the stock reeds and i did. Now it idles and I believe the old reeds use to stick. The bike performs great with the aftermarkets but has a hard time in the low rpms and high rpms. So what I figured I went to the dunes and turned the gas half way and the bike ran like a beast. Could it be my pilot jet to large?
