Hello, I’m having a hell of a time trying to sync my carbs on my beautiful 1974 750s, Is there anyone out there who would be willing to come and show me where I’m going wrong, I live in Maidenhead and obviously willing to pay for your time, thank you.
If you want to come to Chichester, i’ll sort it out for you!
I am too far away (Bristol) but for starters Some points
(1) have you got gauges? You need two Dial or rod style to synch well- check them for accuracy by connecting both to one inlet and noting down the difference on will certainly read higher than the other.
(2) First time most people synch chokes they get confused because the more open throttle (counterintuitively) sucks LESS. This is because both are on the same crankshaft at the same speed so the gas flow is quicker through a small opening. As you open a throttle screw that needle will drop.
Sorry if that is ‘teaching you to suck eggs’
