Something has taken a giant shit and it sounds expensive

Its back together mostly, still need to put tank covers and plastics/seats back. It starts and runs fine, but wont idle. I never touched and air/fuel or idle adjustment screws so wtf? Guessing it may have something to do with the cable.

If it doesn't run, my offer may still stand

Good luck bro

Haha yeah I'm going to need that luck. I'm not so keen to sell it since its going somewhat lol. Rode it to the shops to get dinner. Tons of power went well no hesitation stuttering or bullshit, but it just will not idle which is a bit of a pain. Tomorrow it shall be fixed.

There should be a large phillips screw attached to a cable thats connected to the clutch cover. Give that a few spins clock wise and try idling it again

Thanks guys. Did this and now its idling again, I did wonder if if I had to play around with it since I got that new cable. Went for a run and it seems good, a mate adjusted the clutch for me too, not so much a problem I just didn't like it engaging right at the end. So the problem was basically dirty carbs apart from me breaking/replacing maintenance parts along the way lol. Overall fun, apart from thinking I'd fixed it and then finding I hadn't. Bright side is I can do this stuff again on my own now.

air pilot circuit on carbs.

...told you it was fucken hilarious.

Its still being a slut. WTF? I don't understand it. It fucks about hesiitates, wanks and bogs when you need the power, taking off, on a hill, wanting to power out of a corner etc, When you don't need the power, it comes on like a freight train half way through a corner. Fucking thing, I've done pretty much everything I can DIY. The carburetors are all clean, I made sure of that. Could this be a tuning issue? Would the carbs need balancing?

you had the carbs off to clean and you didn't sync them

now you get to take them off AGAIN.

(or, if your bike has nipples, buy a vacuum gauge.)

If it's fucking about at the top end it suggests a more serious problem than carb balancing. When you had then off did you check the float level? Have you checked for air leaks on the intake manifold? Have you checked the mechanical side of things, valve clearances, compression etc?

Not so much the top end, I notice when riding its more the mid range anywhere between 8 -12,000 - its good after that. It was better for a while after the clean but now its like I never touched it. Its not totally un-rideable, it does have a slight miss right through the rev range while off the bike, steadily increasing throttle. Its not huge but its enough to take the fun out of riding.

Have you thought (I would be about now ...) that you have bought a lemon???

**ducatilover** · 21st January 2013, 12:57

Has it got a standard exhaust and intake?
Have you correctly gapped the plugs?

8-12krpm suggests you need to raise the needles, or look at going up a jet size
After doing a carb sync, build a manometer, no need to take the carbs off to sync them (bench sync without a vac guage/manometer doesn't sync them properly)

Bike is 100 Stock. Plugs are 2 weeks old but good point I'll check them. Just ran it before and its missing right through the rev range, I seem to notice it heaps at 8-12 rpm. Carbs may need an ultrasonic clean?

Yeah I have had that thought for a little while now.......

Check the leads to the plugs are not shorting out on something ... What kind of plug ends do you have? It's a long shot, I know, but I had metal caps on plug leads - they had got wet and rusty ... gave me an intermittent spark - I replaced the metal caps with NGK ones and the problem disappeared ...

Also, if you have been working ont he biek check all the vital electircal wires .. I once broke the copper wiring in side the insulatin sleeve ... couldn't spot it from looking at it ... gacve me an intermittent problem ...
