Old school throttle gage...

You all may have seen this tip long ago.
When checking carburetor settings it helps to know what internal parts are metering the air and fuel.

Out on the street I find myself shifting up at about quarter throttle and a lot of calm cruising at 2500-3000 rpm is just a bit over an eighth.
I haven't used 3/4 for quite a while!

My stock throttle grip has 2-1/4' travel from closed to fully open.
The gage is just a strip of paper taped to the twistgrip clamp.

How many have ever used something like this?

I've read of this throttle marker for over a decade but yours is the best and the first I've ever seen, thanks. I've got so much need of it on Peel special may inscribe it on the switch and grip. 2500-3000 is lovely pleasure state I too enjoy in small towns or leaving pavement. At least give it some 5000+ blip ups a lights and stops to clear the carbon coke out the system and lay down some ZAPP start up protection. Float fuel level sets baseline for all the rest of your diddles. Amal intended 1.5 turns of pilot jet as optimal middle ground, so fun to diddle float level to approximate 1.5 best idle each side, but its mostly for fun as even I who preferes to do this in past has such fine start and idle with each pilot under 1 turn out I ain't bothered to finer tune. Higher fuel level tends to draw up spray tube easier-faster so might notice a bit more off idle grunt or make up for slide bore wear.

My float levels are set real well.
If I forget to turn the BAP fuel tap back on after a stop, the bike runs out of gas after about 100 yards!

Ugh that's a heart dropping then rising event I have happen about once a season. Just realize you are about as nerb as I've heard on fine tuning details, which may rub off on me too.
