This is a VNA project that I procured recently and making slow progress
Bike was bought in boxes and not going
To kick us off
1. Everything has been stripped
2. Welded up the frame
3. Ordered a bunch of ebay and SIP parts
See my related thread on UA carbs
At this stage, unless I find some UA parts , the VNA piston port rebuild is a non-starter. It needs a crank and drive shaft as a starter and I'm not reading good points about the piston port engine
