I've got a set of pattern inlet manifolds for my 650 Special, they came very cheap from China IIRC.
They work OK once you can actually manage to force the carbs into them, I've had to resort to using a piece of wood as a lever (against the frame tube behind the carbs) in order to force the carbs home, and even then, there seems to be a mis-match between the depth of the recess in the manifolds and the carb bodies, not quite deep enough by the looks of it.
OK, so I can mount the carbs and it runs well enough, but I'm not really happy with the manifolds.
Are there any better pattern ones out there ?
Or am I going to have to source genuine Yamaha items ?
