Fuel Gauge Bouncy / TPS setting up

[wardy2015]

Hey I have a 99 fazer 600 firstly what a lovely bike does all i need and a bit more but


1. the fuel gauge is annoying me when some part of the bike gets wet either rainy day or when washed it bounces up and down depending on the revs until what ever it is drys out i have put grease in the bottom of the tank and plug but still the same any ideas?


2. iv just balanced the carbs to acheive an extra 8mpg upto 48 now yay but when i checked the tps value it was 5200 revs not 5000 is that ok or should i adjust it to 5000 i dont like touching if not needed


3. can anyone tell me what tyre pressures it should have 160 rear tyre and 120 front


thanks guys am new to all the fazers had a bandit for my first bike and just upgraded

Welcome to the forum wardy.


Can't help you with the fuel guage, not heard of that issue before.


TPS is close enough i'd say, bearing in mind it jumps to 0rpm or 10000rpm when adjusted so i'll hazard a guess that it's okay to leave alone.


Standard tyres are 110 & 160.
Depends on your weight, top box, luggage, passenger, etc, what pressures you go for, but it's also what suits you as well.


I personally prefer 36f 40r, and find that if i go below these pressures the bike tends to wobble a bit. I'm 16 stone and always have a large top box on the bike. 
You'll probably need to try a few pressures over time to feel what's best for you though.

The bike has a TOTAL max weight laden recommendation of 187kg, that's everything added.
So be careful, as you alone takes away 120kg, plus any heavy clothing, helmet, etc.


I'd say 36f 42r for your tyres, they're quite common pressures to use.

The original rear shocks are not known to be too great to be truthful, and changing the fork oil from 10w to 15w firms up the front quite a bit, but that's all in good time.

OK thanks guys and fork oil prob after Xmas just putting some new dust cover on them today as they are wasted but the seals are ok

Also just rode to work wet and no fuel gauge issue today it's all weird

15w oil makes a huge difference in my opinion, really makes the front end more managable in comparison to old 10w oil.


The fuel guages are a bit weird on these bikes, you can go 50 odd miles without it budging off the "full" position, then afterwards the needle will start dropping, but i don't ever recall a needle bouncing about.
For the record you have an 18 litre fuel tank, and i've always said a good, but obviously rough, guide for mileage on these bikes is 10 miles per litre of fuel, give or take depending on riding style, speed, and so on.
Later bikes have 20 & 22 litre tanks.


This is worth a glance.

Hello and welcome 

the owner manual say for heavy guys like me 16 stone:

2.25 bar = 32 psi front
2.9 bar = 42 psi rear

jacking up suspension on max front and rear has worked fine to me.

You can download plenty of stuff here like service manual, owners manual etc.

If my front goes down to 32psi it does not feel right at all.
36psi on the front is MUCH more stable and recognised by many on here as being more suitable for these bikes, unless you are a lightweight with no extra load.
