I haven't ridden a speedway bike but have done what you are talking about,if you look on my Motubike thread you will see me on the Rosebank Speedway track on my Rickman.I also used to race on the dirt track on Waiheke Island,that was a pear shaped track,so a little different,I used to ride a farm quad around there too,and had a go on a Yamaha 3 wheeler dirt track bike with Hoosiers.What sort of surface do they have,loose or hard packed clay?
The best tyres to use on a stockbike are speedway rears,they are made for it of course,come in 19in only,but you won't get much better for that purpose.Next best are competition trials tyres,the hot set up was a winter on the front and summer on the rear,it pays to cut one side of these,but you don't have to - use low pressures,your body weight in stones was the theory...9st,use 9 psi etc,adjust from there.You need a big fat tyre on the front - when you back off and lay it into the turn it will push like you've never felt in your life,you gotta ride it like that to the apex,so you need a tyre that will let you live there.You need a 19 or 18 on the front - a speedway bike runs a 23,but powerslides all the way round,it can be done on a stock bike,but it's not the fast way.
With your quad you need to get right off the seat,just your right leg on the seat,put your head under the bars and get it sideways all the way around.I've never been able to do that,but seen it done often enough.
If you need some real detail set up pointers,I'll get OWLMorris to come online - he held the No1 plate at Rosebank for about 4 years I think,he wrote the Stockbike Solo rules...pages 83 and 84 in your MNZ rule book.
