Finally got around to comparing the 5 speeds.
85 tri z
1st gear 2.38
2nd gear 1.75
3rd gear 1.41
4th gear 1.14
5th gear 0.95
86 yz
1st gear 2.14
2nd gear 1.75
3rd gear 1.36
4th gear 1.14
5th gear 0.95
So my z is an 86 but has the 5 speed was hoping 5th gear in the yz was taller to give me more top end but it doesn’t. The z 1st gear is pretty low was debating on swapping it needed some opinions. Might change 3rd too.
