WE HAVE A 2002 CR 125 THAT HAS A LAG WHEN YOU SHIFT TO A NEW GEAR. IT'S LIKE IT NEEDS TO "CLEAN OUT" FOR A SECOND THEN IT TAKES OFF. THE BIKES RUNS & STARTS GOOD OTHER THAN THE LAG. IT HAS A 53 REAR SPROCKET AND A FATTY PIPE. I AM GOING TO CHANGE THE JETTING FROM 410 TO 390 TO SEE IF THAT WOULD HELP. ANY IDEAS WOULD BE APPRECIATED. NEXT STEP IS A TOPEND?
