Hi
The best advice I can give is find a rolling road with a good reputation. There is a lot too a dcoe to get them set up.ie-choke sizes,emulsion tubes,idle jets,main jets,air jets,air/mix screws,balancing, the list can go on if there second hand due to wear. They will be able to set the ignition timing to suit.
You may find doing it your self can cost more in the long run.not impossible to do but can be costly if attempting at home

Regards
Jim
