My guage is gradual, but doesn't include the reserve as stated earlier.
I am thinking of adjusting the sender unit, and will let you know how it goes.
One other thing I did to my SC1, was wire the two head lights together for high beam, makes night riding in the back blocks a lot safer, much better spread.
It's the same as when you hold your finger on the pass switch, high and low both on together.
I checked the amperage draw, and all should be fine, time will tell.
After my first service,(two days time) I am going to remove the air box restrictor, and rejet the carbie.
Then I might make myself a pipe.
