F4i with 2k miles bogging and running like crap?!
Ok so i bought my 01 F4i a month ago and ran fine. It only has 2700 miles. It started to bog a lot in first gear and low rpms of other gears. Now it is getting worse.
I replaced all spark plugs, oil change, ran a few tanks of fuel injector cleaner and still nothin? I have also put in the manual cam chain tensioner.
Symptoms:
-bogs at low rpms(especially first)
-smells like gas and blows out smoke
-runs good in colder weather
-while the motor is hot i have to give it gas to start again
Where do I go from here?
Is it possible that i have jumped a tooth on the timing chain?

Definetly check the air cleaner first... Seems like really low miles for an '01. Good chance it sat around a long time with gas in it. If that is the case then running injector cleaner may not get all the varnish out of there. I think that bike is fuel injected (right?) so there could certainly be some issues there. Did something happen to it? It ran great when you first got it and now it bogs? How long, how many miles before that happened?

Ok... I have pulled the air cleaner several times and everything looks fine. It did sit around for a while before I bought it says the previous owner. I have ran almost ten tanks since i have bought it so i wouldnt thinnk that varnish would cause it to run worse and worse. And yes it is a fuel injected bike and i belive it would throw a code if it had to do with it as it has a FI engine light. And I have probably put around 300 miles on it before it started bogging.

I would check the ignition timing with an ordinary timing light. If the timing ain't advancing smoothly, and it probably isn't, don't bother changing anything else.

Any more ideas??
