I used longer MSR as many of us.
Its end was too low, but moving the lever up by one or two teeth was impossible because of interference with the engine body at the point shown. Some time ago I tried to reshape the gear shifter lever. As appears I was unable to bend it for the required angle even in vise using a huge hummer. I made a test cut and ... yes, it is very, very hardened steel! What a "genius" design! Now picture this; the bike is falling on the left side and such hard lever would bend the gear shaft like a nail. Sure, I discard it without any regret.
Before ordering a different lever, I decided to get some practice on the stock one, made from the softer steel. Reshaped it as shown.
That exceeds all my expectations. It is way more convenient than the longer MSR lever and than the stock one. A little longer (just 1/2 inch) would be even better.
