Although the instructions don't say it, I believe you do need to lift the tank out of the way to get to a few connectors. In your case that won't be an issue as you would have to remove the tank to do the air filter install. Do post photos of the installation, I'm curious to see where the unit sits exactly.
Ok the K&N is fitted. Looks like the dealer just lifted up the tank and rammed the original filter in there looking at the state of it. I can't believe how much of this fucking bike you have to strip to get anything done. It's worse than the SF.
I have run the loom around. I have tried to put the box everywhere in a better place but there is just no room for it. Ended up undoing the bracket on the top cylinder to get enough cable to fit it where it says near the front. Only other option is under the passenger seat by notching out a groove to fit the cable. It may still end up there
