IRRATIC IDLE

I HAVA A 2001 HERRITAGE WITHTHE 88b ENGINE. ANDREWS TW55 CAMS, FUELLING OIL PUMP, VELOCITY STACK, DYNO JETS STAGE 1 KIT, AND THE 2000TC IGNITION MODULE BY DTNATEC. RUNS GREAT ALL WAS WELL UNTIL A REALLY HARD RIDE TO THE CENTRAL COAST AND BACK ABOUT 300MI ROUND TRIP. DID IT IN ONE DAY AVE ABOUT 90 M.P.H. AFTER RETURNING HOME THE BIKE HAD AN IRRATIC IDLE ANDTHE IDLEMUCH FASTER THAN NORMAL. PULLED APART AND INSPECTED CARB (OK). REPLACED PLUGS AND WIRES, INTAKE AND CARB SEAL. ITS STARTS IMMEDIATELY AND IDLES OK BUT WARMS UP FAST AND STARTS IDLEING IRRATIC. I SPRAYED IT DOWN WITH CARB CLEANER WHILE RUNNING HOPING FOR A VACUME LEAK! NO SUCH LUCK! DID I HURT THIS MOTOR? FLOAT A VALVE, SPUN BEARING WHAT? I HAVE FUEL AIR AND SPARK BUT IDLES IRRATIC AND SEEMS TO HAVE LOST SOME POWER NOT MUCH THOUGH! PLEASE HELP IF YOU HAVE HEARD OF SOMETHING LIKE THIS. THANKS.

RE: IRRATIC IDLE

Did you try to adjust the idle AFR mixture screw?

RE: IRRATIC IDLE

Take a look at the connexion of the exhausts with the cilinders and the exhaust gaskets. An air leak there makes the bike goes as you describe, with irregular idle.
