I have just purchased a TS1 with 700 odd miles on the clock.
It has a Koso 34mm Carb and JL 3 Exhaust.
When I rev the engine the revs sometime dont drop completely with closing of the throttle.
I've checked cable etc and it all seems fine but I've noticed the carb slide looks like it rattles as it slides back down and hence fails to shut smoothly and quickly.
It also spits a lot of fuel everywhere !
I'm not 100% happy with set up so probably going to change for a 30mm Dellorto and get it on a rolling road but wondered what others here think?
