Help Help Help Add Info

Just picked up my Rocket III after 500 oil change and install of TORS pipes, CAT-ELM
and K&N underseat filter. Bike sounds awesome BUT Hard acceleration at various rpm's
cause misfire's it also has the decel backfire as well. I'm going to try the 12 minute tune
and see what happens the service desk wasn't sure if it had been run. Needless to say
thay didn't put down the tune number. Will post when they get back to me. Any thoughts,
idesa, try this, etc. HELP Thanks for all the info, the Tune number is 20219, I'll try the
12 minute tune, wish me luck. Taking donations on tuneboy. It'd 70+ here in Mass. I don't
know if I have the patience for the engine temperature to drop it reading 96 F. I could go ride and let it cool overnight just to be sure its cold decisions/decisions.

Check vaccum lines.

Without tuneboy or PCIII you are stuck with decel popping.

The correct tune for the Classic with TORs/cat bypass is 20219. If your dealer can't document that they installed the correct tune, they should re-do it.
