Cheers @Unfazed for the part numbers and the o ring heads up, will be very useful.
The TPS was a new pattern part of dubious origins, however it seems better than the mikuni original that I’m assuming is the actual original. As said I’ve not had the time for too much involved investigation but I’m hoping to get into the guts of it a bit this weekend, still have to investigate the possibility of a restrictor kit as suggested early on in the thread. Im not sure the likelihood of an A2 restrictor kit on a bike this old (also isn’t it technically too powerful for that as it can’t be more than double the A2 limit?) and if it’s an old 33bhp kit I think it has a bit more than that but who knows - need to inspect the rubbers anyway.
Not sure it’s ready for a K&N just yet, let’s just make it work properly for now

My nephew has just passed his test and has an FZS600 with the restrictor kit fitted. It is just washers in the carb inlets. The FZS600, unlike the FZ6, just squeaks under the threshold for restricting.
As for the K&N, they really smooth out the power by allowing the free flow of air. Well worth adding if you have a non standard, maybe even a standard, end can fitted. Make sure you balance the carbs again though.
Another ex-Fazer rider that is a foccer again
Oh I didn’t realise it fell into that bracket, thought it was a bhp or two over the threshold.
Anyway I have a decent set of intake boots and an ethanol friendly carb kit on their way. Looking at the state of the rubbers I’m not sure they’ll survive the ordeal of removal to get a look inside them. Hope this works, the way things are going with new bits we’re going to have two part worn tyres with a brand new Fazer sat on them.
Will certainly be looking into a K&N or similar assuming we can get it running right first. I have a race can to suit in my garage, need to order a link pipe but she’s not convinced lol.
Common misconception, as the FZS600 is 95PS which many assume is 95BHP.
95PS which is about 70Kw and within the limit for 35Kw restriction.There were a few FZS600 with a factory restriction of 25Kw, but I think it was only the Foxeye models
One thing I didn't know until recently was that the A test must be completed on a bike with a minimum power output 50Kw.
My nephew had to borrow my FZS600 a few months ago for his A test, because his carburetor model 2005 Suzuki DL650 has a maximum power output of 49Kw.
Hey all. Apologies for not getting back sooner, been busy buying a new bike and stuff so never got to the Fazers carbs til today. Anyway got them out no real problems with that, no restrictor kit in the inlets so ruled that out. The rubber boots were like new on the inside but I’d already bought replacements so put them on anyway. Took off the float bowls and found rust particles in the bottom that had partially blocked the jets. Cleaned it all up and reassembled them. All back in easy enough although the air box was a pain to get square on the carbs. Shook the tank up and drained some fuel through the tap into a bottle with no sign of rust so I’m hoping it was from a petrol station with nasty tanks? The guy lived out in the sticks so maybe. Will check the filter periodically to be on the safe side.
So the bike obviously goes a bit better, still feels a bit wheezy to me but maybe I need to look at my expectations? I notice the exhaust is particularly quiet on it, far mor mechanical noise from the engine and transmission than the exhaust unless the revs are right up there. Is the standard silencer particularly quiet on these? I could do with a more familiar owner to have a listen and maybe take it for a spin.
Personally, if it was anything air related I'd be looking at the air filter.
I had a dodgy paper one many years ago that made the bike sound stuffed up, which is what prompted me towards getting a K&N.
Bit of a ballache but why not remove the air filter and start it up and see if it sounds any clearer? Wouldn't really advise taking it for a spin though, just in case you very unluckily suck something into the engine, but you're not a newbie so should hear a difference.

Not a bad shout that, I did examine the filter while reassembling everything and it looked good. However who knows where it came from, never noticed any obvious markings that pointed to a manufacturer on it.
Speaking of parts manufacturers I meant to add, the manifold rubbers I bought were Tourmax ones. The markings on them were identical to the originals in every way, right down to the ‘5DM’ Fazer code and the manufacturers logo and so much cheaper than the Yamaha packaged ‘genuine’ ones. Don’t know if this is well known on here but hopefully it’s of interest to someone?

You can't really "look" at an air filter to see if it's okay, unless of course it's obviously filthy.
I reckon the one i had was simply too thick as far as the paper was concerned, or just a knock off and poorly made. It only lasted a week before i changed it, as my bike also sounded and felt like it couldn't breathe freely. When i put the K&N on it was like that feeling you got when you took off a covid mask. 8)

I meant I examined it for filth ?

Update…
Well Darrsi wins the virtual prize, a performance filter has done it the world of good. Free revving and sounds less 70’s and much more like a modern bike. Unfortunately it’s SORN’d at the moment so can’t test ride it but I’m pretty certain it’ll go a lot better. Although now the idle is creeping up a bit if left to run for a while, not sure it’s particularly a problem so will keep an eye on that once I can get it up the road.
But anyway many thanks all, particularly Darrsi and Unfazed. Appreciate everyones input, great community here. Now if I could just get some more illumination out of the feeble headlights ?

I will gracefully accept the prize. 
Glad to hear it made a difference. Which air filter did you go with in the end?

I went for the Pipercross one, purely on cost. If we were planning to keep the bike longer we’d have gone K&N but the plan is to get her some experience on this tatty bike then look for something nicer.can’t test it properly at the moment as it’s off road, I've just bought a second bike for myself and had too much tied up in tax and insurance on three bikes before she ‘buys’ it off me.
She’s ridden the Fazer on a private road a few times in preparation for her more formal training and loves it so we’re thinking of maybe looking for a nicer example when the time comes, maybe a 2003 model? These look to me just to be a more modern looking fairing with better lights, have I got that right or is there more to it than that? The other thought is the later R6 engined model but that seems to be held in less regard going on the little bits I’ve read about it. Doubtless I’m be researching and seeking opinions on here nearer the time.

Pretty much as you've said. The lights on the 02/03 models are H4 bulbs both sides with far superior reflective panels than the older models. To be honest you'd be hard pushed finding worse lights than the older models, which is why a lot of people have used add on spotlights which work very well.

We stuck some whiter/brighter bulbs in which I’d say improved things marginally. I reckon crappy reflectors are crappy reflector regardless of the bulbs you have in there. But it looks more modern at night at least lol.
I’m pondering chucking the headlight unit in the oven to see if I can open it up, the brighter bulbs really highlighted the cobwebs and dust inside which can’t be helping it any.
Shame really because I was really impressed with the way this bike rides and handles (and now presumably goes?) for an old girl, as long as you don’t want to ride it out of town in the dark

I've tried the Philips Xtreme, and Osram Night breakers, and they're both decent bulbs, but wasted on these headlight units, as the reflective panels are simply shite.
I personally added 2 x 10w spotlights and they give out at least twice as much light on top.
