4.77 here and LE1605

 

How do you like the shifting with the GM Synchromesh? Is it better or worse than the Honda stock fluid?

 

I found shifting better with the Syncromesh than the honda fluid. plus it fixed my occasional grind.

 

I used to use GM Synchromesh, but have found the new formula Honda MTF with the green label works well. For the diff, I use Bel-Ray Gear Saver. It is a GL-5 90w as is spec'd by Honda. It is also available at my local motorcycle dealer, so no special orders and shipping costs.

 

Transmission: Amsoil MTF (I also liked Royal Purple Synchromax)
Differential: LE1605

 

I use the same combo. LE1605 is much better than Mobil 1 75w90 I used several years ago.
