Hey Guys I have an 09 1125r with just under 9k.. The other day on my way to work I gassed up (same gas everytime) and headed out. About 10 miles down the highway I started to feel the bike miss here and there.. I rode it out for another mile or so and pulled off an exit. The bike was running on 1 cylinder and the only code I got was a lean rear cylinder code. At almost any RPM above idle it would have normal power and run decent (miss here and there).. I got it home and swapped coils and made no difference. Did a compression test and got 120 psi after 5-7 puffs (as per service manual) and put a new plug in the rear cylinder. I'm wondering if anyone has run into this and hope someone can point me in the right direction. Could a valve or two be too tight in that cylinder? A vacuum leak possible? I appreciate any help I can get! Thanks in advance
 
Found my issue! Turns out my rear injector is leaking pretty bad just flooding that cylinder.. I was able to take them out and bench test them (flow and leak test).. hopefully someone can use the info in the future!
