Carb tuning aid ... possibly
Not long balanced my carbs with my home brew manometer, went very well indeed. The balance screw though is soooooo sensitive, the slightest touch throws it all over the place. Perhaps I should have used a slightly higher viscosity fluid along with the air valves. Anyway, it occurred to me that if I could adapt the adjustment screw to mimick the idle screw, there would be no need to remove the air box etc. And no need for using a screwdriver for adjustment (just a turn of the knob)! Anyone ever thought about or tried this? Doesn't look to be a difficult thing to sort.
What's your thoughts. |

Off the top of my head I'd say that sounds like a good idea. Actually surprised that none of us have thought about doing this before. It would need an accessible mounting bracket so that you could lock the adjuster after you've done.

Re: Carb tuning aid ... possibly
dont bother is my take on it. carbs dont need balanced that often. if they do then there is something else causing problems. attaching anything to the adjuster could cause it to move with vibration.
what is of use is permanent vacuum spigot extenders. |

Re: Carb tuning aid ... possibly
Object of the exercise was to make the job of balancing a little easier, not to do it more often. The adjustment knob will be locked off anyway after balancing. As far as I'm concerned it's a 'win-win' situation. If no-one bothered with modifying/improving their bikes we would all just blur into biking insignificance.
The permanent vacuum mod is as you say a 'must have', but combined with the adjuster mod ...could just makes the job a whole lot easier. Last edited by gadget; 30-06-20 at 06:38 PM. |

VFR800 Idle adjuster cable might work.

Re: Carb tuning aid ... possibly
I'm all for modifications but I agree with Biblio,
Check here, https://cx500.000webhostapp.com/SV650Carb_Balance.html If a user wants to add a spigot extender they must allow for the extra tube length in their calculations e.g make sure when connected to the,"Balancer" both tubes are of the exact same length otherwise they will get a false reading and never be able to get a correct balance. Also the tubes need,"Restrictors " in them to stop balance fluctuations. The,"Carbtune 2" I bought over 15 years ago is still one of the best made quality pieces of kit I've ever bought and still like brand new and so easy to use. http://www.carbtune.co.uk/carbcust.html HTH
