Indeed as Keith has mentioned ,Alf Hagons JAP resided in Australia untill his son retrieved it not that long ago .It was raced down under by "Fast Eddie" Castle and the spanners were spun by Col Moon.It came to Australia in 1969,and at the time Alf was criticised by a Brit motoring journalist for selling the bike "to a corner of the world where sprinting is is almost unknown" (which in retrospect is kind of funny and half true ,as Aussies are more into Drag racing than Sprinting).
Cheers RM

Hope he enjoys the book when he gets it.

Drag racing and sprinting is still going strong in Britain.
I imagine there are a few riders over here who would like to get hold of a 4 inch Avon replica at a sensible price. Be interesting to see if anyone produces one.
By the way, it was good to see the pics of your dad's old bike. It has a nice clean look.

if you want no traction, old school ,tire spinner style just run a street tire. it won't be a "drag slick" but it sure will spin. there are no rock hard avon or bruce slicks any more and even if someone repops a tire it will likely be a modern compound.

I sure wish I had one of those sticky tires you're talking about when I was running the four inch Avon and M&H tire...wouldn't have needed a Wheelie Bar either, just rode it different...even back then some of us was using the clutches available and sliding them by hand with the clutch lever and throttle...the Barnett Sintered Iron Clutch plates were available in 1971 and their Cork Clutch plates before that could be used as a hand slider, you just needed to have something to keep the clutch lever back (I had a piece of alloy hanging on a string on bars) so they wouldn't stick together until cooled down...and you'd had to change clutch packs almost every run though...

I can inagine that was quite a balancing act, trying to manually slide the clutch Joe. Could you manage to get it pretty consistent from one run to the next?
Am interested in how much ETs improved by slipping the clutch instead of the tyre. But as you were always trying new things to go quicker, I guess that it is not an easy thing to put a number to.

Keith,

Yes it is hard to explain...It started as far back as the “Smoking the tire runs” when we turned the throttle to the lock and dropped the clutch and smoke it for 800 foot but even then I learned to slide the clutch some, that's when even though I was smoking the time I found if I let the clutch out first and then turned the throttle to the lock it loaded the motor some while smoking the tire and I went quicker and faster still smoking the tire... The night at Irwindale when I was a little late with the throttle and the motor bogged and didn't light up the tire and I turned my first 9.0 ET it opened the door up to a new way of riding...after learning to do that every time with out killing the motor on the start line another door was open and I begin riding that way and sliding the clutch by hand which also required some work with the throttle and that was using Barnett Cork Clutch Plates...then came the Sintered Iron plates from Barnett and I built a 14 plate Sportster clutch which I used as a hand slider for a few years, then came the Slider Hat a Machinist friend and I built that fit on a Sportster Clutch...during this time came the M&H tires Joe Mondello of Venolia Piston got started for the Bikes and the many M&H four inch tires I tested for them at Irwindale....the many clutches and motors I went through while testing those tires...

Irwindale was my Home Strip and I was there every day and night it was open from 1963 until it closed it doors...making as many as 10 runs every time I was there...

Good to see all you new guys joining us.


Some time back someone posted a picture of Zack Reynolds, who was RJ Reynolds grandson, and I said I would post some more info on him. This is his most famous and fastest dragster that I watched him race. He called it "The Flying Hog" which was a neat name. That is him next to his red and white Harley somewhere on his Winston-Salem, NC estate. He was a hell of a racer and as you can see was very light.

I wish some of the old British Fuel Bike racers would join us and share info like Joe does with the Harley guys. Boris Murray and Arno St. Denis are still around but neither have posted here. Maybe some of the old European racers can help you.
