Carburetor Spring

[unfazed]

Ys a common issues, rubber ring get squashed against the shaft. Glad you got it sorted. The reason for my original question was to see if you wete fitting it the correct way around. You would not believe what I have seen with TPS fitting. ?

Thanks darrsi.
I am going to buy that one that you send me. Thanks for that.



I kind thinking that that rubber ring could not be possibly be part of the carb. because when i removed it if fits on the TPS but it leaves a 3mm gap from where it sits on the TPS and the end of bottom of the TPS if you know what i mean. So when i connect it to the carb that 3mm gap wont fit properly as the rubber does not pass the edge of the role where the TPS sits so the TPS is not flushed with the carb and to do so causes a lot pressure on the screws and locks the butterflies.


see images
First one is the TPS without the rubber and without screw in. See how it fits perfectly. and if i tied the screws the spring snap back closed the vents.
Second shows the TPS with the rubber on. you see where it sits and the gap it leaves.
Third on is the TPS with the rubber connected to the carb. See the cap and to make it flush there is to be a quite pressure when screwing the tps in place.

Hey All.
I finally figured out!  :rollin :rollin :lol


Whomever had changed the TPS before me had jammed the rubber all way inside the groove where the TPS sits on the carb. I mean jammed in! I could not even see it.
So no wondering the TPS was not going in properly and was jammed the butterflies vents.

Thanks all for your great help!


I just ordered a new TPS as this one was giving me trouble.


Thanks again

Just be aware if you've recently done a carb balance with a possibly faulty TPS then the carbs won't be set right so will need doing again once the new one is fitted.

Great thread and glad you got it fixed mate. I myself am also fairly new to Fazers and one of the things I liked about them was the help and community available on this site.


A word of advice (As I have to take my carbs off again cos I didn't do this) do your best to bench sync the carbs before you put them back on. This will help to balance them later and also familiarize yourself with the location of the balancing screws so it's less of a fiddle.

bench setting is always a good start i did a massive video on balancing my carbs and found out someone had made a cockup previously

at 8:30 there was a spring set wrong that screwed everything up big time and it took me 6 months to find
(carbtune showed me how bad it was that i had to figure it out)

Thanks for the advice.
I have done that following a this google link. Here it is for anyone that needs it in the future.

Hey Guys. Just an update on this.
Thanks again for all the inputs and suggestions.
I got the new TPS yesterday - thanks again darrsi! changed the throttle cable and installed the carbs. Spent couple hours trying to get the cable slack right - jesus they could not find a better place to put those screws locks!
But could not get the throttle to snap back in place. Removed the the throttle cable holder on the handlebar and start thinking that the last owner might had changed the original handlebar grip as it was a bit tie.
Solution: Got my power drill, connected a metal brush and removed the excess of inside of the grip.
Bingo! Throttle cable slack adjusted and throttle snaps back. 


Now going to sync the carbs.
Can not wait to put this beast on the road again.


:lol
