Does my bike have a restrictor kit?
Discussion
Hi everyone!
I bought a 2007 Kawasaki ER6-F last week and went the through the paperwork in detail and saw that a restrictor kit was fitted last year. I wasn't told at the time of purchase by the bike store that it had a restrictor kit fitted.
Does this mean they removed it? I do not know how to check for a restrictor kit. It's my first bike so I wouldn't know the difference if one was fitted or not.
Does it have an impact on the bike in any way? Fuel consumption better or worse?
I will be calling the store later but just want some information so I at least know what I am talking about.
Thanks!!

Does it have any effect? Yes, it will probably be cutting the power output of your bike in half.
To tell if its there, you need to look in the air intake trumpets by lifting the fuel tank and air box, if you see washers sitting in the trumpets, they are restrictors. Alternatively, they may be in the exhaust downpipes, which means removing the full exhaust system, which is not so easy to do at home.
Tbh, if you are new to biking, you probably haven't given the bike a good gunning yet, so the difference between 33bhp and 65 or so BHP may not be immediately apparent to your arse dyno.

Hi Mastodon
Thanks for your reply.
I know it will be cutting the power from 71bhp to 33 bhp but as you mentioned I have not given the bike a good gunning, even if I did I would not know what the bike is capable of.
My main concern is the bike shop, I dont want them to lie to me and say there is none fitted when I take it to them later today.

Why would they lie?Thanks for your reply.

You could probably lift the fuel tank and airbox yourself, getting the exhaust downpipes off is a bigger job, you'd probably want to lift the bike for easier access, the undertray might need to come off and the silencer might need to be detached from the hanger, then it's a case of undoing the bolts holding the downpipes onto the engine and looking into them to see if they have restricting washers in. Maybe ask the dealer if you can watch it being done so you're assured it's not there / to learn how to do it in future.Thanks for your reply.

As for not knowing what the bike is capable of, have you passed your test for a full licence? Even as a beginner on my lessons, my arse dyno could tell the difference between the 74bhp CBF600 and the 52bhp CBF500.
One easy test would be to give it some stick on the way to the shop, if it can reach it's top speed of 130mph, or at least crack 120mph if you can't find a road long enough (and private, of course), and struggles to get beyond 100-105mph or so, it's almost certainly got the restriction in place.

I did pass my test on a full license but was never able to open up the throttle. I rode both 650 and 500 in one day when I had lessons so it was easier to compare.One easy test would be to give it some stick on the way to the shop, if it can reach it's top speed of 130mph, or at least crack 120mph if you can't find a road long enough (and private, of course), and struggles to get beyond 100-105mph or so, it's almost certainly got the restriction in place.
I have done a 100mph on it but not more because it sounded like the bike is reaching its limit (I wasnt aware of any restrictors at the time). Right! Im off to thew shop now
Ill fine tune my arse dyno on the way there

2nd gear, open it up low revs to the redline.
If it's quick but runs out of puff higher up the revs and feels 'flat', particularly above 5k. It's restricted.
If you get a second lot of oomph, and it feels zinger higher up the revs, after 6k. It's not restricted.
Great tip Jack! Have built up the revs in 2nd and it doesn't run flat.If it's quick but runs out of puff higher up the revs and feels 'flat', particularly above 5k. It's restricted.

I'm much happier now.
Have a great weekend all and thanks for all the advice and tips!
