I posted a query a few weeks ago with regards to my gen 1 hanging on the revs after throttle was closed. This occurred after fitting a full monty kit. Riding further up the rev range proved to be a much improved result, however, this 'lean' situation with revs 'hanging' was hugely irritating. I knew immediately that the problem was down to the pilot circuit running lean but have only just got round to sorting it.
Whilst drilling the pilot air holes a fine swarf found its way into the circuit and partially blocked up on 2 of the carbs.
The solution this evening was of course to 're remove the carbs and drop all of the pilot screws completely out and clear the circuits with carb cleaner. Bike now sweet!!
The main point of course here is to pass this info on because as far as I can remember there is no mention of removing the pilot screws to effectively clear the circuits before setting mixtures. I believe most guidelines just tell you to set the mixture screws up and then undertake all of the other operations and then refit the carbs.
Anyway, I hope this 'heads up' saves other budding enthusiasts wasted time on a second removal of the carb bank!!
Cheers.
