Anybody with engine knowledge know if this 70 setup would fit on the Nanfang?

Well I've paid for one, just need to wait until it arrives now...

The standard unit actually gives an indicated 55mph on a downhill section of road and sits quite happily at 40/45mph on the flat.

I think that's very decent overall but I'm sure the Speedo is pretty optimistic!

Still getting bogging at lower revs.

Did a couple of different settings with the floats today but didn't seem to have any bearing on the engine at all ..

Did notice it was a 78 main jet, does that sound a bit on the small side? :?

Hi
My friend’s just bought one of these
It’s not bad for a 50
It will slipstream my 90 up to 55mph 🙈
Did the 70 bore go straight on?

Cheers

Yes, a very simple conversion.

The standard unit was far too gutless at the bottom end for my liking but did an indicated 57mph down a slight incline

They are nippy enough little machines but the bore kit made a significant difference.

Seems that the seller I bought mine from has new stock in again (I got the last one supposedly)...
