Deffo a rich problem as it get worse when the engine warms up.  Pilots out to 3 turns is worth trying, bear in mind pilots aren't always set to the same number of turns.

Will check, mine were different initially, carb work in the morning then, i wonder what's causing the fuel leak at the tap from the fuel line, only happening under load and not leaking with the tap on while static, blockage maybe.

You could try the throttle blip test Cliff.

 

  • NOTE: A rich problem gets worse as the engine heats up.
    • If the throttle is lightly "blipped" at idle, and the rpm drops below the set idle speed, then rises up to the set idle speed, the low speed mixture screws are probably set too rich: try 1/2 turn in, to lean the idle mixture.
  • NOTE: A lean problem gets better as the engine heats up.
    • If the throttle is lightly "blipped" at idle, and the rpm "hangs up" before dropping to the set idle speed, and there are no intake leaks and the idle speed is set at less than 1000 rpm, the mixture screws are probably too lean: try 1/2 turn out, to richen mixture. Be sure there are no intake leaks and the idle speed is set at less than 1000 rpm!

Brill thanks i'll reference that when i need..

 

So i've pulled the fuel tap, dunno why it was leaking, vibration !! or summit to do with me carb issue, emptied the tank but fuel seems okay without any crap and the filters were okay.

 

Carb issue

 

First i checked the fuel height on the left carb and it was around 7mm LOW, right side in spec as they both were when i fitted them, having done the fuel height on the bench, so that was odd, took float bowl off and cleaned everything again, float bowl had no shoite innit and the jets gotta ultrasonic along with the housing, reassembled add fuel and rechecked the float height and it was approx 2mm above spec, odd again, was reluctant to start adjusting the float tang as i knew it had previously been okay, then noticed fuel leaking from the drain screw, least i think it's from the screw but when i popped the hose onto the float drain spigot the leak stopped at the screw but dribbled slow out off the hose with the screw done up......swapped the drain screw over to opposite sides and the same problem with the right screw, so i could have a damaged seat on the cover or the cover has a crack innit, but nowt i could spot... 

 

So while under way and bogging down the drain offs had hose attached which seem's to prevent the leak at the screw but it's their none the less, and am assuming this is the source of my woes.. leaking draining fuel so the bowl is not full but would'nt that mean the bike is lean now !  confused..

I could only see the crack in my floatbowl when the drain screw was fully tightened up. The crack ran along the length of the casing where the screw goes.

I could'nt spot a crack with mine tightened.. so can i correctly assume a leak is obviously enough to give me erratic revs !

 

Just spotted this video by shane connelly, worth checking this method..

No idea matey. :lol:  I guess it could if the fuel level is all over the place.

 

Good test in the vid, it'd help identify if there is a leak going on. :good:

Cracked float bowl, on the inside visible, fixed that with loctite quick steel epoxy type stuff, sets in 10 minutes flat, looks like the taper on the drain screw wont seat either so had to lose that, still it's a working bowl.

 

Finally got around to starting her up after dinner, pilot screws set 3 turns out, still spitting and back firing a bit, more the right carb, i'll be setting the battery up off the bike so i can fiddle with the pilot screws a little..bassads to get at..

Cheers, if i find i'm struggling to curb it with the pilot screws do i need to think about changing the clip up or down a notch on the jet needle.

It's not something I've ever done, from memory the only times I couldn't get a response from adjusting the pilots was when the choke plungers were rotten, think the end had snapped off in the hole and the other occasion was an air leak on the scottoiler vac connection.

Who are you kidding, them pilot screws are a bollox to get at, one had fell out, no wonder it seemed odd trying to screw the bleeder, had to lift carbs to find out, 

 

Bike struggling to start off jump leads and bike battery (car batt needs a run, could'nt use that) so i put the battery back, i set the pilots at 3 turns out, did that with the carbs propped up so i defo know it's 3 turns, warmed the bike up and did the blip test which shows Rich, battery back out turned em in 1/2 turn, battery back in  :lol:  still popping away, sounds more aggressive .... and that's enough for now.

 

Incidentally when revving now it's bogging between 2-3000 rpm

 

Really need to have the battery set up off the bike to see if the pilots will make any difference.

 

All i can say is Arse.....

 

Edit.. i think at this point i may need to pull the carbs and give them a clean up again, i'm thinking shoite still somewhere as no noticeable change on screwing the pilots in 1/2 turn...

So th blip test still showed rich ?  Just wondering if the pilots need turning out to 3 1/4 to lean.  Did you try balancing the carbs ?  I found going from balancing to pilot adjustment and repeat is sometimes necessary to get them balanced properly.

I'm just sat here thinking that exact thing, especially as i can see the sliders are not in sync with one another, i'm also thinking i should of tried to even them up a bit even without gauges which i will have to order. Sure you or drewpy or both said to sync already..

 

Can i try and sync with a warm engine initially or should idle be below 1000 rpm for best.

 

So i've turned them in and richened,  out to lean and in to richen then !  The blip test method you posted has the pilots turn IN to lean mucka..

 

Just shows how lucky i was when the carbs were cleaned a couple of years ago eh, okay aint giving up, the bitch will work..

I'm really confused now ?

 

"Turn in to lean the mixture, turn out to richen the mixture"  was what I was advised the other day.....

It might just be one pilot screw needing adjustment and a carb balance, esp. if the sliders aren't in sync.  Could also be air getting in past the diaphragms, or one of them.

Just lower the tickover as low as possible without stalling if you can't get it to tickover at 1000rpm.  You might find that after a few adjustments, the tickover will need lowering and should improve.

 

Factory pro say that for CV carbs..... Turn in to lean the mixture, turn out to richen the mixture.  But, I seem to remember some confusion about this being mentioned on here years ago.

Well, that's interesting....  

 

Without having a gas analyser, I suppose the blip test will be a good indicator.  But only if the carbs are balanced.

Gotcha i've found the same as Factory pro on a Ducati forum for the same carbs but your saying it MAY be out to lean if turning them in makes no difference ?

 

Defo out of sync now though.
