Hello I have recently purchased a 95 vfr 750 interceptor it’s been running great so far but I’ve had a few problems and wanted to ask the forums for some advice

one thing I wanted to ask first is when turning on your 4th gen vfr is there a significant whirring sound you hear for the fuel pump as in my 2007 ninja 650 you can hear the humming of the pump before starting the bike but on my vfr I don’t hear anything.

i was cruising down the highway at about 70 miles per hour when I lost all power to the bike it just started bogging down and no mater how much throttle I have it it wouldn’t go and ended up dying on the side of the freeway I got it home and replaced the batterie after trying to bump start it for a bit the electrical systems just when completely dead try to turn it over and just hearing clicks. After replacing the battery it started up no problems. After the battery replacement it has been idling high after running for a bit somewhere between 2-3500 rpm I’ve adjusted the idle screw which has brought it down.

since it’s ran again which I go out every other day to start it for about 5-10 minutes to keep the fluids moving. While riding there are moments between first and second gear where the bike starts to chug along while accelerating only happens when giving it some throttle instead of smooth throttle I get this kinda lunge where it feels like towards the back wheel it’s almost skipping. 

 

between the dying on the highway issue and the skipping issues I was hoping to hear some advice and or similar problems and the solution y’all took to fix them. I’m already looking at replacing the fuel pump and fuel filters. With the potential of cleaning my injectors (which I plan on doing soon anyways just wasn’t my first step due to the process to get to them) also wanted to check out my throttle assembly in case I’m missing something on that end.

thank you for your time and reading this long question.

"is there a significant whirring sound you hear for the fuel pump"

Yes & No,  It only runs when your turning the engine over or the engine is running, so you might not hear it.  It's a clicking sound.

This is not a good idea.  I'm not going to get into all the reasons, other than to say it's not a good idea".

" cleaning my injectors "

The Gen 4 (1994~1997) do not have injectors, it's has 4 carburetors..

I agree with scup33's points.

Keep in mind that the battery gets recharged by your VFR's alternator, via the rectifier/regulator and the starter relay. Any of those components may be faulty, as well as the wiring and connectors that link together. 

Idle speed should be 1,000 rpm give or take 100.

If you don't already have them, owners & service manuals can be downloaded from

It's worth it to do a quick voltage output at the battery, idle and 5000rpm.

Got a multimeter?
