HELP! / Re: 2013 Turbo Hayabusa wonít idle

Also, Iím not sure if this is the same, or separate, issue as the 4-5k limiting (but Iíll find out soon)
I had similar issue a while ago but it was happening at around 6-7k and the bike was ZX10R. It was the faulty side stand switch that vibrated and killed the ecu. And then again but with GSXR600.

Remember, if you're taking a reading at the plenum, you won't get any vacuum. You need to take a reading behind the butterflies. Take the reading at the vacuum hose at the bottom on the throttle bodies.

 I was only able to find my leak at the bottom of the throttle bodies when I inspected based on where the top portion of the lower boots should be on the throttle bodies. Mine looked fully seated until I noticed the whole thing was about a quarter inch up from where it should be. I had to loosen all of the clamps and smack the crap out of it to get it to go back down.
That being said, pressure test or vacuum test is best way to find the leak.

Not the silicone couplers, but under the throttlebodies , as you have idle problems your problem is below the throttle blades which could be air leak, fuel supply and also including spark plugs , and compression

test the throttlebodies with crc or similar when idling  ,

also the rpm limiter from 4-5k is that still happening ? does it loose power or miss , thats the point things should start happening on the fun side of things

Based on my initial visual inspection, all of the vacuum lines looked to be in good condition, and the throttle bodies appeared to be sealed to the head and intake manifold. This made me think that there shouldnít be a vacuum leak all of a sudden. After reading all of the input, and looking at anything else that might be responsible for the issue, I went and bought a vacuum gauge. I hooked the vacuum gauge directly to the intake manifold, and found out that I have 0 psi of vacuum. So Iíll be spraying the area to find the culprit.

Also, Iím not sure if this is the same, or separate, issue as the 4-5k limiting (but Iíll find out soon). I havenít been out to test it since Iíve had the issue with the idle.
