Sounds to me like most people here want midrange performance improvement, and are happy with the 600's top speed?

Hi does anyone what i would have to get tuned or changed if i was to put high rise cams in it :\

Simple answer to the original question - trade it for a gen 1 thou :lol
Seriously though, what gave you the idea to go for high lift cams? Curious.

Fzr 600 cams are exactly the same in every way appart from the power peak its more violent than the fazer so a straight swap of cams should give me a nice powerfull kick

A kick, OK, will it improve max power though?
How would the FZR cams fit on? And what about piston clearence?

Put more air and fuel into the cylinder...
I think it all depends on what op means by faster?
Faster in a straight line? if so your buggered without throwing big money at it, in which case you will be better off with a different bike..
Faster to ride? This can be cured with better suspension and brakes and of course practice..
Re: How do I make my 600 fazer faster????? - JoshVaughan - 16-08-13
The difference would be in the aggresive clime of the revs compared to the standard fazer's, the fzr 600 cams are made so the vaulves open and close quicker there for increasing the way the power would climb instead of the fazers smooth power but ive never seen anyone attempt it but they do fit cause ive got a set of fzr cams and they fit fine but i dont want to put them in without knowing what im getting into
Re: How do I make my 600 fazer faster????? - nick crisp - 16-08-13
From what I can gather, the idea is to increase fuel flow to the combustion chamber. This can be done via camshafts either by increasing lift of, or by increasing the duration of opening of the intake valves. But there are some things to be careful of. You must have sufficient valve to piston clearance for the lift you wish to achieve. If you take 2 cams with identical duration but one has higher lift, the valves on the high lift example will open more rapidly. This is desirable as you should strive for the nearest to instantaneous opening that you can achieve (actual instantaneous is impossible). However, at extremes it can result in valve bounce, where the valve is effectively propelled by the speed of opening rather than following the cam profile. To counter this, you could use heavy duty valve springs which would give more control over how the valves open. I think maybe high lift cams would also make the engine more peaky? (i.e. less torque/mid range but more top end revvy). That's about as far as my understanding goes, and I'd be interested to hear from someone who really knows what they are talking about!

Is this aggressive power curve you speak of not the characteristic of the exup valve??

Be careful, your cylinder head and cam caps are machined together for very close tolerances, and must be carefully matched for the cams.

A higher lift but equal duration cam gives engines more low end torque, as a rule it's the duration and overlap that give an engine more top end power.
A good explanation is here:
http://www.streetracersonline.com/articles/camshafts/
Something to note though, is with higher duration cams there's more valve overlap, which is why engines with cams like that run like shit at low rpm.
Although the rules on overlap on the site change with forced induction; you don't need as much because the turbo or supercharger is forcing the mixture in, so can minimise it at low rpm.

Swap every nut, bolt, and part, like for like, with an R1.
You should find a huge difference in seating position, acceleration, and general all round oomph.

How can i make my bike slower?
Answer: Buy a car.......sorted :b
Re: How do I make my 600 fazer faster????? - stevierst - 17-08-13
I used to do quite a bit of engine tuning in my younger years, swapping cams, porting heads, bigger carbs etc....... It rarely makes the bike "better" for the road, peaky power delivery, boggy at the lower end, stupidly high tickover that's lumpy as fook, nightmare to ride in traffic. Overheating, unreliability, the list goes on.
You'll gain a little power by cams/head tuning, but won't necessarily make the bike faster. The best tuning you can do, is get the suspension sorted, then some advanced training, or track tuition. THEN it'll be a lot quicker! You watch a good rider on a 400 hit the twisties, he don't need massive power, just big skill!

James May experimenting with the FS1 (Fizzy) is a perfect example
Bikes are made by boffins after years of modifying and getting things just right.
Admittedly some materials used in construction are questionable, like exhausts, sprocket nuts and headlights, but the bike as a whole is well engineered, reliable and fun, and probably at it's peak state of performance 90% of the time off the shelf from new!
If you want a quicker bike, buy a quicker bike......it ain't rocket science!
Re: How do I make my 600 fazer faster????? - darrsi - 17-08-13
Or buy a rocket......but according to "Fuelly" their fuel consumption is pants!
Re: How do I make my 600 fazer faster????? - Chris - 17-08-13
fit a turbo....
Seriously though, without spending big money and then having to spend more upgrading suspension etc then it's really not worth it. Small gains can be had, as mentioned already, by k&n air filter and a decent exhaust but the bhp gain is tiny, a few bhp at best. After said mods my bike definately rides smoother and seems to pick up speed better but that may all be in my head and because it sounds nicer then it feels faster...
Spend your money on a few track days/tuition or on a bigger/faster bike.

Yeah, that follows everything I used to read on the subject - conventionally high-tuned engines don't run very well low down - however I once rode a Z1R that had been heavily breathed on by John Carpenter (legendary Kawasaki tuner of Mistrals fame), and that thing was rapid! Also it didn't seem to be too bad low down, and idled ok.
I wonder if a decent carbs/exhaust route (maybe flat slides or just larger carbs with necessary mods elsewhere) might not be a better way to go?
I used to read loads on this tuning subject, but I was younger then and didn't really understand half of it, and I've probably forgotten most of the rest!

Haven't looked at your link yet, but will when I have more time. I read that high lift cams work better with forced induction. Is this just an obvious thing or are there particular reasons for that?
