im a mechanic, what size motor you runnin and give us a run down on your spark distribution and carb type? also as soon as it does that check for gas down carb?
Its a custom built 750dp carb, was originally intended for 360 cubes but then changed plans and stroked it otherwise 950 probably would have been a better size http://www.zokracecarbs.com.au/
The carb is super responsive.
There were a few small electrical issues that were sorted on the dyno, Not real sure about the spark distribution but as previously mentioned it runs fine when cool.
Also runs fine around town when warm.....it just has issues when warm and highway driving.
Love this motor but, it will smoke street tyres at 60mph
