evening i'm trying to balance carbs as i type but using 2 gauge instead of 4 so do i put pipes from gauge to the cyclinders next to each other if you know what i mean.

think you do 1,2 then 3,4 then 2,3

i also have the same gauges as in the pic,where should the needle be whe carbs are correct.

correct

Doesnt matter where they are as long as they all read the same

doesn't matter now i've gave up,when turning the screws the bike kept cutting out then wouldn't start and so on so i put it all back together and took my anger out on the wife.

did u raise the idle to about 2-3k rpm?it shouldnt just cut out. did you take both the pipes off that block off where you put the balance guages if you have unplugged the two you arent balancing it will keep cutting out!!as its a massive air leak.you have to have the ones you arent balancing at the time blocked off.............this is why it is easier with 4 guage balancers
when balancing the carbs you have to be very gentle you only need to turn the screw an 1/8th of a turn maybe less then let it settle again for a minute and repeat till the same.go back and have another go tomorrow or something it gets easier when you have done it a couple of times, and your be suprised as to what difference it makes to the bikes running.
hope this helps

Yeah at first i was wondering why it wasn't starting then tried covering the two open ones and it started so i got the small tube that that was linking 2,3 and put this over the two that wasn't being balanced,started to balance 1,2 and got it somewhere near so changed over and started to do 3,4 and then started cutting out when doing these ones.i get this when i'm out on the bike that when it gets hot it won't start again until its cooled down a bit.i'll try again tomorrow.

Just finished it now think i have it spot on now,much better than paying someone to do it

glad you got it done in the end just a little bit of patience see, and there are plenty of people on here willing to give some advice to help you along the way.

Thats why we are here

Well done, doing things yourself is very satisfying, not just as an achievement but also when you havent had to fork out for someone to do it! Paying for parts only is a win all the way.

thanks lads for the advice

so by balancing the carbs what does i actually done to the bike,what effect should it have on it etc?

does what it says......you have 'balanced the carbs' which means they are all at the same level now .....you will just get smoother running and idle and maybe pickup better depending how far out they were.just means all 4 are all working at the same level

level meaning speed. Those screws adjust the butterfly's that the throttle opens and closes. Due to valve clearances changing and wear within the carbs, it causes each carb to run at a different speed making the bike run lumpy in tickover, increasing fuel consumption because all or some of the carbs are running at different speeds so are fighting again one another.

Hve you taken the bike for a spin yet? IT should be alot smoother on tickover and pickup better as extonyg said. Were they far out at all?

yea took bike out last night seems to be better they wasn't that far out to start with.One thing i noticed that when i did them first and messed up they were a bit out and loads of toad kept blowing out the exhaust like oil or petrol or something,it was wet and brown anyway but now i have them right it has stopped.

Also i noticed while fixing the gauges on that where the mechanic had put the restrictor washers there is fuel leaking out of them as if there not on tight enough,could this be an air leak, should i replace the rubbers.
Wish i still lived in telford,i might of been near one of you lads that knew what there on about to take a look.
