Hi Fellow Foc-ers! (Is that alright to say?!)

So I have been using your info for the past few week helping me rebuild a 2001 FZS600 that had been off the road for 5 years.

It’s been a fantastic learning curve so far, but now I’m struggling…

It doesn’t like being in a low rpm and pulling away.

1st gear pulls away okay and the engine seems happy,
2nd gear, below 3,500rpm it judders quite viciously,
3rd, 4th, 5th, 6th, it bogs down below 5000rpm.

It would likely judder in the higher gears at a lower rpm, but I wouldn’t be in them at any low speed.

It doesn’t Idle without the idle adjust screw/butterflies opened a bit, but even then at 1250rpm it surges every couple of seconds.
Pilot adjust screws are set at 2 turns, though have tried at 1.5 turns and 2.5 turns which don’t make too much difference to idle speed.

Above 5000rpm the engine really sings now, and pulls constantly well especially after the work I’ve done below (previously it even bogged down at 7-8000 rpm), but none of the jobs have rectified the low speed rpm judder.

The clutch does seem to make a chatter on idle.

It does smell like a rich mix on idle, I.e too much fuel?

Soooo,

Following reason other people’s advise on here,

I have stripped the carbs,
cleaned/rebuilt/balanced/jets cleared/all pipes flushed. (Balanced visually when carbs removed and with a 4way vacuum gauge)
New orings fitted on main jet and float needle and float needle valve (remembered the 4 little screws hold the valves)
Fitted new air filter (though not k&n)
Fitted new iridium spark plugs even though originals were brown and gapped well.
Replaced cracked carb/engine rubbers
Emptied as flushed fuel tank.
Checked caps for sparking and they do all spark well or at least sound like they do, and don’t arc in the dark.

I have a new fuel pump (not yet fitted) as I thought it was fuel supply when it bogged down under high rpm.

What have I missed? Fuel/air mix? Float level? Clutch issues?

Any help would be greatly appreciated as the bike is fab, just not round town and don’t wanna have people look down on the Fazer as I rev the nuts off it and feather the clutch at 25mph through town trying to stop the judder!

Many thanks!!

Hello


I need some room in the garage so am looking to sell my black 2001 fzs600

• I’ve owned it since 2018, currently around 42000 miles. MOT Valid until October. It’s been serviced in the last 500 miles. Brand new PR4 tires fitted 2000 miles ago, along with new braided brake lines on the front, new pads on the front, new chain and sprockets (standard gearing). Also put a new battery in it a month ago.
  
• USB power fitted with the output on the bars. Also has a quadlock mount fitted which can go with the bike if wanted.
  
• It’s got a small crack to the front fairing and a few small scratches on the top of the tank caused by grit getting under magentic pad of an old tank bag. Other than that it’s a tidy bike.
  
• It’s currently registered on a private plate, but will not be sold with the bike.
  
• I also stuck a beer clutch pack in her last summer, so less than 2000 miles on the clutch too.
  
• Located near Milton Keynes.
  
• Metzeler roadtecs were on when photos taken, now has Michelin PR4s.

Hello, today i finally got my fazer on the dyno after i ivanized it. The guy claims that it runs way to rich. He's saying that i need to get the idle jet 5 sizes smaller, the main jet 10 sized smaller and put the clips on the needles 1 step higher so the needle gets lower.
Can someone help me out here, i've done everything the way ivan described it.

Hi Peeps.


I'm on the hunt for a mint pair of 43mm Fazer 1000 stanchions.
I'm near Barnsley S/Yorkshire,  so if any of u fine Foccers have a pair not in use, I'd be interested if not too far away from me & the price is right.
I would prefer to view & collect.
Obviously they must be straight & free from pitting.
I will consider complete forks, but I only need stanchions for my rebuild & it's not easy to see a bent stanchion on a complete fork leg.




I would like at some point to upgrade the front end to R1 spec, funds don't allow at this time  :'(

Hi all,
as title says Im looking for Stock linkage dogbone for FZ1S (2009). Recently I got myself a Fazer and it is lowered too much, it is unacceptible for me plus it is very hard on the road. I dont feel safe driving it, no fun at all.
Maybe someone has it somewhere hidden or wants to get rid of it?
Part 24 on here: https://ie.fowlersparts.co.uk/parts/6451...c/rear-arm
Thank you.

The Government has released a way to check if your motorbike can use E10 fuel.

- https://check-vehicle-compatibility-e10-...ufacturer/

As a very rough guide, anything pre-1990 or so could be in trouble. The problems you will get if you use E10 in a non-compatible machine is poor running and potentially deterioration of the engine performance over time. The actual negatives are not clearly expressed by Government statements, and it’s hard to get definitive information.
