newbie looking for some help

Postby paulyblue » Wed Jul 10, 2013 5:56 pm

Hi
My name is Paul, and I have owned my 4xv for a few months now. My last ride was an old zx6r so I have taken my time with her expecting some big surprises, but sadly its just not happening. She fires up on the button and the throttle is nice and responsive and the engine sounds sweet with no smoke, pulls well but once she is warm thats when the bogging down starts. Its like riding a 2 stroke with full choke. No grunt at all at slow speeds and I have to slip the clutch at round abouts.
She has a stainless system with no Exup, could that be the problem? Should it have been re jetted? Mates tell me they can smell petrol behind me. Have given her a service - plugs, oil and filters and ran some carb cleaner through the system. No difference, still the bogging down.
Does anyone have any advice that could help a bloke on a budget? Am really not enjoying myself and now regret getting rid of the Ninja.
Any help would be much appreciated.
Paul.

Hiya Paul and !welcome to the forum

Have you had the carbs balanced at all
Have you checked the air/fuel adjusters are set correctly (should be fully in then 1.5 turns out)
Also check the vent hose from the tank isnt squashed
And the crank vent to the air box isnt squashed

If you can afford it then get it on the dyno :thumbsup

BTW where abouts are you ?

Get some proper clips around them as cable ties wont seal them up properly

Unless its been set up properly after having the exup system removed it will be a pig to ride in the lower revs.
Even if you get it set up/rejetted it will never be as good as it would be with the exup valve still in place.
The bike was designed to run with this and there doesnt seem to be many people who have managed to run them well without it.

So would you recommend just getting a set of standard headers from ebay rather than trial and error with the jetting?

It may be cheaper and easier in the long run unless there is something else wrong.
But I wouldnt want to recommend anything as its not my money being spent.
Do a bit of digging around the net and see if you can find anybody that runs without the exup valve with no problems.
Most people who ditch the exup valve seem to run race bikes where low down revs are not needed.

Just out of interest, hows the coolant?

Mine did that and i foud the level was way too low, and a flush and refil fixed it.
This is my bike. There are many like it, but this one is mine.
It is my life. I must master it as I must master my life.
Without me my bike is useless. Without my bike, I am useless.
