For MFR Hyper Pulley LETS 4

Fits: SUZUKI LETS4
We used LETS 4 for ADDRESS V50.
View detailWeight roller is NORMAL 6. Because I was using 5 g or 7 g, the included 5. I think that it is too light at 5 g, 6. We purchased and installed 5 g together, but unexpectedly 6. Even 5 g it was too light and it came back to NORMAL with a ceiling at 45 km ~ 50 km.
We are going to purchase a slightly heavier Roller.
