| Thanx for the reply nakes, i checked the floats individually, and they seem fine, i just dont know how far they should be adjusted, but when u say could be the carb rubbers, this sound possible to me, coz they do look a bit old, but how does this work, only when on side stand?? |

Float height on VFR is 6.8mm according the Haynes.
So maybe for some reason they're not sealing 100% when the bike is leaned over on the side stand... |

| The vacuum on the front right cylinder (top left of your picture), is actually in the side of the head, rather than at the back of the inlet (and should have a 20mm long screw rather than a 6mm one like the others) |

The jets you got will be fine for a standard filter, not the foam one you have.
I would really recommend fitting a new standard filter, there aren't really any performance gains to be had by fitting foam, just a headache when it comes to jetting, mainly the fuelling transition from needle to main jet.
Re washers under needles: The standard needles should have 0.5 mm washer already, you can use 1 mm washers, but you must take the standard 0.5 mm washers out, so that there is a total of 1.0 mm washer under each needle. It willl run too rich if you've left the standard 0.5mm washer in and added an extra 1.0 mm.
Sounds like you're jumping into this head first. At least you can see the errors that previous owners have made and are finding out about them sooner rather than later! Looks like other owners had been tinkering a bit much.
Forgot to send that manual through hennie, will do so on/after the weekend mate. |

Hi Cammo,
I didnt see any washers on the needles when i took them out?? but do you think that i would have seen any if there were? wouldnt they be loose? and what u think about the fact that it idles wierd when on side-stand?

Could this be that Thick screw i found under the carbs? and what effect would it have if it were taken out?

Yeah you should have seen some washers if they were there, they just sit loosely under the needle. With your 1mm washers it'll now be spot on!
Haha, I'm no expert on all this stuff, but yeah, incorrectly adjusted floats sound logical regarding your side stand problems. |

I'll adjust the floats tomorrow then, i recon there's no need for special adjustment after doing these mods?
Oh, and Cammo, i noticed, that when i rev the bike now, she revs great but when she's at idle and i quickly open the throttle to rev her, there's like a small delay before she revs, not that she doesnt rev good, just that delay, would drilling the slide hole to 2.5mm have an improvement on this, or is the risk too high? what are the risks or side effects on drilling the 2.5mm holes? |

I also have that small delay/hesitation, I think it happens when the airbox harmonics have been altered (yours has been with the foam filter, mine runs no airbox/filter).
The delay won't be noticeable when riding it in real world situations, it's not often you snap the throttle open from idle on the road!
Once you've adjusted the floats, your carbs should be in the best condition they've been for ages.
There are no drawbacks from drilling out the slides, no harm at all. Since you've done the rest you may as well do this! Just make sure to go no bigger than 2.5mm.

| Ja, drill those holes bigger with a 2.5mm bit turned by hand... don't use a machine. |

Regarding the needle washers - sometimes the washer will stick in the slide if there's a bit of fuel in there, but you probably would have seen this when you put the needles back in.
Not sure if you've checked this, but while you've got the carbs off it would be a good idea to do the pilot jets. With your exhaust and filter, start at 2 1/4 turns out probably. That might help with the slight throttle response delay. And it's amazing what previous owners will set the pilot jets at! |

Thanx, but i dont fully understand, do u mean the pilot jets or air mixture screw's should be turned out 2 1/4? because i set the mixture screws to 2 1/4 out already? the pilot jets are mos inside of the carbs next to tha main jets, please conferm your last post please
thanx
