I changed my plugs, put in new diaphragms (3 out of 4 had lots of holes), ran seafoam, synced the carbs, and my mileage went all the way up to 40mpg.
Recent tanks it dropped to about 35-37. So I did the modification whereby I put in a small crankcase filter, and plugged the holes to the airbox and removed the "T" fitting going up to it. Many thanks to skydoc-13 and his write up on how he did this.
My mileage is back at 40mpg.
One of my cylinders warms up just a tiny bit slower... when i check it with my hand...(back right). I'm not sure that is the problem.
Bike runs well, starts right up.
Should I recheck the sync? How often does one syc the carbs? The plugs are clean, I have lost 3 mpg somewhere!
Thanks
