Hello,

Just installed the R77 full exhaust. Sounds so nice! I am noticing that the idle is a bit high ~1700/1800 rpms. First thing I did was check the adjuster, but it isn't even in contact.

I know this bike is EFI, with an ecu and all that. What would be the first order of business to drop this idle?

Check adjustment of TPS. Is there an idle switch and is it activated at idle/closed-throttle position.

Check cable housing adjuster. Might be too tight and cable is keeping throttle plate open.

Also check throttle boot for leaks after throttle body.

The 300 has a high-idle mode for warm-up, kinda-sorta like an auto-choke. Does it ever settle down? Mine runs idle around 1.4-1.6 after ten to fifteen minutes of riding, but she can hit 2k+ right at start from cold.
