Hey guys,
I have had to fill up my tank 3 times this season and am getting about 30mpg. I have also noticed that on the takeoff if I accelerate hard it will kind of hesitate a little before it really takes off. Also, after a 20 minute ride or so, when I come home my girlfriend and I notice that I smell like gas (not extremely strong, but its there).

I am thinking maybe new spark plugs and air filter will be the key? What do you guys think

01 F4i with 18,4XX miles on it.

Edit: I do not ride hard every time I hop on the bike. Sometimes I get on it but I never go past 10k shifts and normally I am riding around 5.5k

 

Usually 2 main culprits for poor MPG on an F4i:

-Power Commander... if you have one of course. Poor MPG is usually one of the first signs of a power commander that's about to kick the bucket

-Fuel pressure regulator.... they stick and make it run rich


But a good tune up with plugs, air filter, valve check, etc wouldn't hurt anything either if it hasn't been done yet. But if you don't have a PC, I'll bet on the fuel pressure regulator being the culprit. If you do have a PC.... unplug it entirely from the system and see if the MPG changes or stays the same

 

I do not have a PC, but the FPR seems like it may be the problem since I have low MPG and i smell like gas once I'm done riding.

 

Huh...I didn't know the PC can go bad and do that. I'm glad I read this.

 

What is everyone supposed to be getting MPG wise? I think I was only getting around 32 myself.

 

I usually average 40-42..... have for the last 6.5 years. I've had lower when I was pushing it harder, and higher when I was going real easy (as high as 47, or maybe even 50 before I forget)

 

I think I just have a throttle control issue. I usually always start hard, even if it's just to get to the speed limit. Just gives me the little thrills I need.

 

I always get 35-40 no matter what.

 

I have a similar issue as the original post. Sometimes my bike hesitates when I take off or if I am riding and slow down (but not enough to go to the next lower gear) then pick up the acceleration and my bike will hesitate.

I too smell like gas/exhaust after I am finished riding.

My bike only has a slip on exhaust in terms of performance or aftermarket power/electrical related parts.

Any ideas?

Thanks.

 

is it weird that my bike will only take 2.5 gals at every fill up? i usually go about 100-115 miles before having to head to the gas station
