Hi guys, Im having an issue with my bike and hoping yall can help.
2005 Hayabusa
Stock other than shortys
The bike would not rev above 9k so I cleaned injectors and now the bike will not idle above 900 rpms. as soon as i turn the idle screw up it dies, along with turning on the fast idle. Behaves fine with throttle, and will rev out cleanly. When i first start it it stays on for like 30 seconds at like 1100 rpms when its cold starting, but once it switches to idle from cold start it slowly drops to 900 then dies. Ive tried replaced the fuel pump, tps, ive checked all vacuum hoses and airbox is fully seated on the throttle bodies. Injectors were professionally cleaned and spray/leak tested. Any help would be great because im about to take it to a shop.
 
Does it have any fault codes? Sort of sounds likea Map sensor issue (IAP sensor) if it is only having issues at idle.

You can try spraying a carb cleaner or similar around the outside of teh TB's and hoses while running, without gatting any in intake tract itself. If the idle changes at all, there is likely a vacuum leak somewhere.
