Mark Harvey has been a speedway mechanic for many years and has a wealth of experience to share with us. Many of you will know Mark as Daniel Nermark's mechanic but he has worked with a number of other riders over the years including Josh Larsen. He is meticulous in his preparation of any speedway machine. Many thanks to Mark for taking the time and trouble to contribute the contents of this page.

Work involved in getting the bikes ready for a meeting.

The bike has to be stripped down from top to bottom and cleaned in a precise way to make sure that any mechanical breakdown could possibly be avoided.
Step 1.. Remove all front and bike covers for cleaning.
Step 2.. Remove Air filter and Carburettor from bike and strip down carb for precise cleaning. Once clean, wrap in clean paper and leave in an area free from dirt or dust.
Step 3.. Remove back wheel and take off rear chain and any used sprockets for degreasing and cleaning. Remove front chain guard and take off front primary chain and engine sprocket again for degreasing and cleaning.
Step 4.. Remove clutch plates and clean until like new. (This process alone takes in excess of 1 hour if done correctly). Once they are clean wrap up in clean towel and place to one side free from dirt or dust otherwise you may end up repeating the whole process again.
Step 5.. Remove all cables to clean and re lubricate them to ensure their smooth working order.
Step 6.. Now you are ready to start to clean the actual bike. First of all you degrease the complete bike to get off all the oil, etc, then you pressure wash off all the dirt and grease. Once this has been done you then wash the bike with soapy water and again pressure wash off. You then can use a Brillo pad to clean wheels and engine plates. After this you then clean with soapy water and finally pressure wash off the excess soapy water.
You then need to make sure every component is fully dry to prevent rusting.
Step 7.. Now you are ready to start putting the bike back together ready to start racing again. The time spent in the workshop is valuable and can never be under-estimated as you will hopefully suffer less or no mechanical breakdowns. The time factor involved in this process is in the region of 6 to 8 hours per bike.
