Gas smell; startup idle/rev issue
Hello all,
So, I've been on this forum for a while and have been searching all over and can't seem to find the answer to these two questions.
1. What can cause me (or what is causing me) to smell like gas when I am around my bike when I start it up/riding/or revving the engine?
2. When I start my bike from a completely cold start, I can't rev the engine right away. (if I rev the engine, it will bog down and seem like it's choking). After about 30 seconds, I can rev the engine fine.
Now, I've read that a bad FPR could cause both issues, so I replaced my FPR. I've read that my air filter could possibly cause issue # 2, so I replaced my air filter.
I change my oil regularly (every 3 months or so, during the riding season).
My bike only has around 4500 miles on it. I also get around 27 MPG.
Any ideas on what could cause these issues?
Thanks for any help/replies.
Edit: If # 2 is normal, then that is fine, I would just like to know.

I've read about the fuel filter too, but didn't think it would be a cause to my specific issues. I'll add that to the list of items to be replaced then.
I guess I'm trying to rule out anything greater like a throttle body or carb issue.
I also have a shorty exhaust and don't know if that could cause any issues either.
Could running sea foam through my bike help with anything?

sounds like my bike. it idles around 600rpm the first 15 seconds of every start-up then after that time is up the rpm jumps to 1500 or so I believe and the FI light comes on. Other than that it runs great wont bog down again until I turn it off so ive just gotten used to the light being on. 4000 miles like this and counting. With the idle that low off the start it does rev up very slow until it hits around 3k rpm
its not going to be fuel, air, or spark issues or the problem wouldn't just disappear and reappear only at start up. Not a likely battery issue either. I've been thinking its a sensor and the bike jumps into a "limbo" mode after 15 seconds and ignores said sensor.
Ideas?

I'm still going to investigate my issue. I will be ordering some spark plugs and will replace them. I'm more concerned with smelling like gas when I am around my bike when the bike is on. It just seems strange, but again, I've read that fouled plugs could cause gas fumes to lurk.
Now, my FI light doesn't and have never come on except for the normal flash when I am turn the ignition to start. You could definitely have another issue.
Have you replaced your FPR?

Anything else could cause gas smell like that (if coming from exhaust), other than fouled spark plugs and bad FPR?
I just want to find this and solve the problem.
Thanks.
