I've changed to using the HKS listed below: -
HKS Differential LSD Synthetic Diff 75W/140 Super GL5 and
HKS Synthetic Gear 75W/90 Transmission Transaxle.
However I find some difficulty in changing from the 2nd gear to 3rd gear at high rpm.
Is it due to the oil I used? Are they suitable for our ride?
Greatly welcome anyone to contribute.
