Aloha, I just picked up this 07 had it for a month and it has intake, 2bros carbon slipons and just got a PC5(previously had juice box but previous owner said it fried). Problem is the bike idles from 1100-1300 and on pcv program shows it cuts out every few seconds to 0. I have change plugs and bought pcv to see if it would help but it doesnt. I've read forums couldn't find a similar issue. Any help appreciated thanks.

Bike has 37k miles, dont know if he did valve check, bike used to overheat real quick when first got it(changed thermostat and flush system), current issue is idle/sputter.
Has bst carbon wheels(which is cool), led lights, carbon 2bros, intake, before I bought it ,dealer just installed new clutch and sensors for clutch lever and kickstand sensor. I think I got a good deal?

Have you done a leak down test or a compression test? Rough idle/sputtering could be any number of things. Those tests could reveal a lot. It's probably worth it to check the valves. I would put the PCV back to the stock tune/flash, perform the valve check/adjustment and then perform a throttle body sync.

Not yet but I ran into a overheating issue and replaced thermostat, radiator, water/oil pump. Also fuel pump sparkplugs and it runs smooth than back to sputtering. I notice exup cables broke away i don't know if that could make a difference but will buy new cables soon and will do valve check when I got time

Please keep us posted. I’m going to change throttle bodies. Might have faulty fast idle system or stepper motor or butterfly link. If that doesn’t work then valve check.

Yes. My idle is worse on my 05. Just recently installed dynojet auto tune welded in stock exhaust with pcv but I’m having no success adding fuel to idle. I can’t even see throttle position rpm when I rev on map cells and auto tune doesn’t come on after 10 sec engine crank time. I changed coils, plugs, cleaned tps, cleaned throttle bodies, adjusted fast idle unit but same issue. Might be rectifier/regulator also.
