I have what I think is an LC350 with the first version of the carbs.
As they came :
Getting cleaner
They have 180 mains and 27.5 Pilots . This doesn`t match standard jetting or modified carb Yamaha settings, but may be an unmodified original carb upjetted from 20 pilot 160 main to the current 27.5 pilot 180 main to suit modified barrels and the Microns it came with ?
Not got the barrels off yet to inspect looking down the exhaust ports they appear to be the early barrel with the top of the exhaust port raised to nearly flush with the notch in the top centre of the port.
Can anyone identify if these carbs are stock or have they been modified , the drilling at 6 oclock has an alloy blanking plug , as do the two small drillings on the outside of the carb next to the idle screw?
