OK Ask him how ya should shim the crank end play with the HK2012 needle bearing.I didn't see any wear from the needle bearing. It has 358 miles on it. I'll call Quenton later today about it.
I have my own ways of doing things. I would change the side cover to one with the 6904 open bearing and use a spacer.
Some history of crankshaft end play on the NE-5.
There were 2 different cranks that can be used on the NE-5 one uses the side cover with the needle bearing HK2012 and the other uses a side cover with an open bearing 6904. Whizzer USA upgraded to the 6904 cause the needle bearing was too sloppy. Like your crank.
But the 2012 is still some's favorite.
All modern motorcycles and scooters use an open bearing or shielded bearing on each side of the crank.
But ya gotta use the correct crank with the 6904 or make a spacer to fit the other style crank like you got.
Same with the 2012 There is bearing holder that Quenton made for the 2012 that will fit the side cover for the 6904 when using the crank for the 2012
We Whizzer guys had to figure out what to do cause some Whizzers were coming from the factory with a crank for a 2012 and a side cover with a 6904 So we just used a spacer to correct the end play. Instead of getting a sloppy 2012 side cover then having to shim that.
Page 3 on this Whizzer Motorbicycles Section threads I have a thread called "New Gen - Crankshaft End Play - HK2012 - VRS - 6904"
dated Aug 28, 2019 you should check it out it explains my view on the subject in more detail
To use the 6904 side cover with your crank I would have to send you a 4mm spacer or you could make or get one yourself.
You would also have to pay $55 for a new side cover and not sure you want to do that.
Ask Quenton how He would shim the crank end play on the 2012. That might be best.
I would just use the 6904 side cover and spacer. I like it better. Once again check out my thread on the subject.
There has always been a problem with Taiwan - Specifications - Close Enough is Good Enough
The 6904 side cover with the correct crank still has a crank end play of 1mm or .040" and should be shimmed for a better running motor
I made my own shims to achieve the correct crank end play of .003" on each side of the crank
By using the 6904 side cover and a spacer with your crank. We can get it very very close to .003' on each side of the crank. Or just use the 2012 side cover ya got Quenton might have a shim for you.
