Nice work on the clutch timeeh :)
Lest you ride your bikes! , ive been interested to see watt happen'd to your bike after broke down at 50% mini sx race.
 
Hey, when you mentioned that the Z155 and the YX150 YX160 clutches are the same, yeah they are.
It's just the Z155Ho and Z160Ho that are different (they are deeper)

^ Same buddy, thought it might of been a small problem as it didnt sound to noisy... but there you go :)

Was'nt noisy as clutch was just gone! haha Nice work trophy clutch now ;)
 
Phils tb basket was on a yx wasnt it? Cause I had to swap the rear gear over on that to use it on the 160ho, was different teeth count..hence my assumption the two gears are different..
 
Yeah the YX use a bigger gear on the Basket, with a smaller one on the crank.
The 67T gear on the 6 plate baskets give's the gearbox a better primary ratio
 
Yep,
So to make the TB basket work with the original gear it came with (69t) from Phil, you would have needed to fit an 17T YX crank gear to your Z160Ho
and it would give your engine more down low, but lose about 10km/h off your top speed.

The difference in the primary drive gear ratios were 4.06/1 in the YX160, and 3.722/1 in the Z155Ho and Z160Ho
