Sat with my first coffee of the day,thinking about my rough tick-over, Yes 45 years on i still find carbs a black art,
Well where to start with is a topic it it's self, I have used colour tunes, and plug chops and balance gauge's..But lets think about whats going on?
Ok, i bet most Commando owners have used Balance gauges...right? But here's my opinion of these; We connect each gauge to the manifolds and frig around with screws.and cable lengths untill the gauge's read about the same...Right? But all "we" are doing is measuring the depression between the slide and valve..am i right so far?
BUT we are not adjusting the air/fuel ratio...if its 14-1 on one side and 12-1 the other there will be a bigger bang on one cylinder..causing a un-balanced engine.
Modern Triumphs Fuel injection systems adjust the air/fuel ratio hundreds of times per second, using a lamba in the zorsts .
So is the BASIC carburation on our Nortons the "added "cause of Vibes? or just the mass of of un-balanced iron flinging about, what i do know is friggin about with settings can cause a better feel..so good carburation air/fuel ratio make's plenty of differance...Any one had better results with exhaust gas meters?
