I,m new to this, but here is my story. I recently purchased a used 2014 1100 R2 with 293 miles. The original owner was a mechanic and made some mods to it, but I'm the guy who has to straighten them out. Would you believe he put an aftermarket turbo on it and because he couldn't line up the waste gate actuator he just put a spring on the waste gate lever to a bolt on the block.You want to talk about boost. That has been fixed. Now for the current problem. When I first got it the only way it would start was if you stepped on gas to start it. Followed some of the tips on this forum and replaced IAC step motor. It now starts fine, but on cold start after about 5 or 10 seconds drops down 500 rpms and hardly stays running until it hits about 140 degrees. I have check the CTS and I just want to make sure I have it right. Some of the instructions in the manuals are a little cage. I checked the resistants between terminal a and c and get no resistants, c and b was 19.75 which is about right concidering it was 27 degrees C. If I'm reading the manual a and c is for the ECU and c and b are for the gage. So I guess that my ECU is not getting any signal, so it isn't richening the mixture when could. Am l correct or not?
