Race prepping the NF4 for it's first race...
The whole process took about two days and I'm exhausted.
Here are some notably pics of the process.
New Vertex piston.
I have hand fabricated a powerjet for the PJ38 carb as it is a handy modification.
And a home made expansion chamber. This took about -almost non stop- 18 working hours! Handmade paddock stand as well. Not rigid enough but it does the job well.
