Hi Jack. I've noticed your using a helical cut gear primary.
I've always been confused as to what is the better option (pros, cons etc) between straight cut and helical cut gears, what are your thoughts on this?

Theres definitely more noise coming out of the primary and clutch, that's with the full metal to metal contact...
When you cycle through the gears its a lot more crunchy with the engagement, but definitely more solid transmission of power... feels like there's less dip in revs between gears.
I was quite comfortable cruising on short highway stints.
The primary seemed bulletproof, not much metal wear in the oil.
But eventually I went back to DRT helical stock gearing 23/65 the biggest reason because I wanted a shorter gear setup (higher gear ratio) and as far as I can see, there's not that many short gear options for straight teeth clutch and primary (all race use I imagine)
So with helical you get less noise and a smoother, softer shift (which is better for me riding around the city)...
Just my none scientific experience, question hijack over...
