Replaced fuel filter. Noticed when the fuel ran out the old filter it was orange in colour. I think my problem is rust in fuel tank. When i looked in fuel tank it looks spotless, so it must have rust at the bottom :\

if you take the tank of and remove the tap and fuel guage sender you can flush it out quite easily    se what comes out  has the bike been sat around for a while

I'm going to take tank off and drain. I've just bought the bike, so i don't really know how long its been lying.

a good flush out then  .........might be good to drain the carbs aswell 

[nickodemon]

Going to do that this morning. Let you know how i get on.

[nickodemon]

Flushed the tank out. The fuel had loads of rusted flakes of metal in it, so i completely drained the tank and carb float bowls. Filled the tank with fresh fuel and went for a spin. To begin with it was pretty spluttery, but i think that was down to the fact carbs were drained and new fuel filter fitted. After about a 1/4 mile the bike ran sweet. Went out again this evening and same again revved out perfectly. I will hold back jumping for joy until i have used it for a few days, but it seems to be running much better

[red98]

mmmmmmmmmmm not good :\ ...................at last i had some spare time in the garage   i used the colour tune on three of the four cylinders (cant seam to reach cyl 3 easily) and set a little bit rich, iam more or less on 5 turns  :\  so start it up and i have a big stutter at 5/6000 in neutral on the center stand  :\  just like hitting a rev limiter and wont pull through  :'(
so i put the mixture screws back to 4 turns (its been running that for the last 30,000 miles) and no change :\
  ive made things worse and i dont know why  :'( :'( :'( :'( :'( :'( :'( :'(

I balanced the carbs on mine this afternoon. While hooking up the vacuum gauges to the take-off points on the inlet manifolds I found the little rubber caps had perished quite badly:

I don't think they'd quite gone all the way through, the one I tried sucking on was OK anyway... I didn't test the others 'cos I didn't like the taste.
As a precaution I smeared some silicone sealant into the cracks.
With all the dismantling and checking you've been doing I don't suppose that sort of thing would have missed your notice, but thought I'd mention it anyway as a possible cause of a weak mixture.

did somebody mention the word fuel perchance?.....and we know what that passes through don`t we?...no Clive, not just fuel lines !! :lol :lol :lol

well spotted fazerider [size=78%]......a split like that would indeed affect the mixture big time,mine are ok,but will double check to make sure ,just need to backtrack a bit now and see what i find[/size]   thanks for your input matey,did you notice the difference now your carbs are all pulling together
