back fires at highway speeds...

[ncbuell1452]

i have an 03 xb9r and on the highway I can be going in 5th gear at 55 or 65 mph and my bike will backfire every couple of minutes....i have the buell race kit on the bike exhaust, k&n filter and race ecm...

Is it a true backfire, or the common airbox hiccup/cough? If it's the airbox cough, do the breather re-route and it will help.

If it's a backfire, you probably need a custom map for your ECM via Xoptiinside.com or Americansportbike.com. (Having the Race ECM doesn't fully compensate for the mods, though it's a better than a stock ECM.)

Either way, a Custom map would probably solve it all.

- in your inlet or exhaust?

- while remaining @ same throttle position or on deceleration?

Here is the Breather re-route. It is quite an extensive thread, the good part (pics) starts from page 2 but I would advise you to at least skim through all of it first, you will find a recommended parts list as well as a few different ideas for placement of your filter. Hope it helps with the backfire. It will help the bike when running at lower RPM's regardless though.

FIDO,

Does the breather re-route go for the 12R as well?

Thank you,

If it's an XB, the re-route can be done. [up]

Yes what they said, all XB models.
