Modern Classes will be run like the Original SUPERBIKERS at Carlsbad
Heats according to categories,
Dirtrackers
Roadracers
Speedway
Enduro
Motocrossers
Starts like AMA Flattrack
6 on pole
6 on 2nd
6 on 3rd
2 from LCQ on 4th
At Barleigh Ranch completely recontoured track resurfaced,
Twins around the outside, Longtrack at 680metres
Singles through the right hander
.
CONTEMPLATING Removal of Front brakes in all classes,
so they learn to back them in !!!!
Airfence onto the main straight .
In my opinion a good Wood Rotax would be unbeatable around any of these tracks
except for Longtrackers

I think the best engine is the Kawasaki ER 650 and the CF Moto copy
Peter Kirkness father of Mick is just finishing the first one for me now,
followed by the Aprilia 550, Suzuki DL650 and Hyosung 650 most of these can be had as write offs on the cheap,
I will start on Barleigh Ranch after the 1st round of MX Nats in April,

I've been thinking about the classing system for this sport and I reckon it'd be wise to keep it as simple as possible first up. Once we see more people entering the sport we might be able to spread the classes out a bit. Here's my 5c worth for a simplified classing to get the ball rolling.

*OLD SCHOOL TWINS:
Open to all American style flat track bikes using Champion, Trackmaster, Redline or similar aftermarket frames or stock frames modified to suit. Twin Shock conventional rear suspension and 35mm forks maximum.
Engines:
*Harley Davidson XR750 and pre Evo up to 1000cc.
*Triumph 750,650 and 500. Meriden built only, no second generation late Triumphs.
*All BSA, Norton, AMC, Royal Enfield, Ariel, Vincent and similar production based engines.
*All Yamaha XS650, TX 750
*Kawasaki W1 650, H1 & H2 triples
*Honda CB 750 (SOHC) CB450
*Suzuki Cobra 500, GT750, GT550
*Benelli Tornado 650 and other Italian engines at the discretion of organisers. (I'm a bit short on knowledge of 70's Italians)
                                                               

MODERN TWINS:
 Similar frame specs to above but opened to newer designs made specifically for flat track like Knight, Cheney (Jerry, not Eric and others. Any suspension combos allowed.
 * All modern Japanese, Chinese, Korean or European twin  cylinder engines allowed up to 750cc. Some triples or engines bigger than 750cc at the organisers discretion.
                                                                                                                             

OLD SCHOOL SINGLE.
Same frame regulations as Old Scool Twins.
Engines:All pre 90 Japanese singles such as TT 500 & 600 Yamaha, XL/XR Honda 500/600, BSA Unit Singles, Rotax, Suzuki DR 500/650 and like engines.

                                                             
MODERN SINGLE:
Same frame specs as Modern Twin.
All post 1990 single cylinder engines over 500 cc (to exclude the modern 450's which have their own class )
                                                                                                                          
OLD SCHOOL TWO STROKE :
Same frame specs as Old School Twins.
All pre 80 two stroke motocross singles in 250 and 500 capacities and twins up to 350cc.

                                                         
At first some of these classes may have to be combined to make for full fields but I'm confident that after a couple of years all classes could front full grids.
'68 Yamaha DT1 enduro, '69 Yamaha 'DT1 from Hell' '69 DT1'Dunger from Hell, '69 Cheney Yamaha 360, 70 Maico 350 (2 off), '68 Hindall Ducati 250, Hindall RT2MX, Hindall YZ250a , Cycle Factory RT2MX flat tracker, Yamaha 1T250J, Maico 250 trials, '71, Boyd and Stellings TM400, Shell OW72,750 Yamaha

As much as I love these baby's and I'm looking forward to watching and maybe even having a ride myself.
There is a part of me that is dissapointed that it's all very American and the Old Skool OZ Dirttracker will fade off into the sunset.
Maybe a class for old OZ Short Circuit bikes can be squeezed in there somewhere and I'm not talking Sliders, although that's another story, I'm talking Duplex framed Brittish engined bikes from the 50's & 60's.

While I'm on a roll.
Personally I think the best way to make it work is to spread it out around Syd to start with.
Maybe something like Raymond Terrace, Nepean & Canberra.

Yay,RT, Nepean and Canberra !! That'd be the go. What about Kurt on his framer Bonnie at the Nats ?  imagine how he would have gone round the Longtrack at Canberra.

BTW, 23rd/24th Feb, Longtrack Challenge at Canberra, Darylene Austin or ACTMCC website for more info.

Might hafta go lookin' for an XT 550 4 valve motor
Dinosaur class Slides , anything, as long as it's really old.
