Fazer Power

Spoon Fed

Hi I just got my fazer 600 'de-restricted'. However the revs dont get past 8000 and its screaming up at those levels. Is this normal?
I fear the bike was actually factory restricted and then shop restricted where i bought it. When they took off their restriction i was left with a bike that is still restricted. I bought it brand new in 2009.

Can you let me know what I should be getting from a full power Fazer?

thanks

How was it restricted - what derestriction was just carried out - what did the shop actually do? On a 2009 bike the options are few and if it was factory restricted it would usually be by using a modified ECU - this would have to be replaced with an unrestricted ECU.

If they restricted it by using restrictor plates in the intakes then it is unlikely it was factory restricted as well but there may be additional tuning work needed to get it to full power. I'd bring it back and ask them to test ride it to check their work.

8000 revs isn't that high for a Fazer - it should rev out past that but will sound very high if you aren't used to it. In first or second gear you should be able to bury the revs into the redline to the point that the revlimiter cuts in. This pic suggests 12k rpm should be achievable;



If you ride the bike will it rev out in any gear? On an open road, stick it in second and see how high it will rev - watch your speed etc...

Restricted bike will max out at 160 km/h
UNrestricted will go on to approx 230 km/h
(Not advisable on public roads)

Only on a planet with much lower gravity and no atmosphere will a Fazer 600 do 230km/h....:D

gravity doesnt effect top speed

should rev out fully as said, and you should know instantly when you twist the thottle, that its unrestricted... you've trippled the number of horses pushing ya 30 to 90 odd

wouldnt have thought any restriction would have an effect on your top rpm, so it could be something completely different... did it ever rev past 8000?

Well, will do 220km/h anyway, but duck down and a bit of tailwind you will get 230 km/h

We tried some in the Isle of Man.

If it's a problem with the revs not being reported correctly then you can test this by driving along in 6th gear. At 6k rpm you will be doing around 65mph.

As others have said, did it ever rev past 8k rpm? Does it feel ALOT faster?

I'd agree with LookBehindYou. With some tail wind and a slim body 230kph is accessible. I can do 200kph easily. But with a GPS those speeds would be a lot less.

Thanks for all your advice, appreciate it.

It is not alot faster. Screams and trembles over 6000. Something definitely amiss.

In fact, I looked at the bike yesterday and spotted a metal tab screwed onto the engine limiting the throttle cable. However, this may still not explain it.

Going back to shop and challenge them to look at it again.

Hopefully they will address the issue or I will be back on here !

thanks again

How dare you disagree with the 'septik!

A factory restricted Yamaha will use a throttle stop for restriction only. They don't do restricted ECUs.

Your bike should rev up to 12k rpm. I have a 09 XJ6 and it has the same engine slightly tuned for more mid range and less peak torque. It revs to 12k redline and limiter at 14k.

Stick her in say 3rd gear on a open road and slowly rev to see if it gets to 12k.

My bike screams all the way to the limiter, although I'm not experienced enough to notice a dead spot up the revs.

Ps kamikazi's obsession with ceptor is still there I see...
