Here's two tips for you.
1. Ride one gear lower than normal. It increases the compression braking,
so you don't have to squeeze quite so
hard on the regular brakes.
2. Reach down on the left side of your carbs and adjust the
idle speed slower. This lets the throttle slides close a little
bit more and adds even more compression braking. In a Florida Monsoon,
I'll set the idle at about 900rpm. You have to keep one hand
on the throttle at stoplights, though, or it'll stall.
