Thanks , that brought back Speedway ! 60' , 70's

The sound of a speedway bike is beautiful. Love it.

Always been a Dream of mine to have a go on a Speedway Bike.

brings back memories from Australia

Rode a 2 valve Jawa, years ago, did a couple of days at the Olle Nygren speedway school after years of watching speedway, to ride one was a dream come true, hope you enjoyed it

Sitting here a few thousand klicks away wishing I could race Speedway. Looks like a blast!👍 In this context only does it suck to be Canadian. Afaik there is literally not a single Speedway race anywhere in tbe entire country.😕 I have to make a trip to Europe someday.

I believe that's a JAWA 894 DT 500 twin Cam 4 valve!

Yes it is a 4 valve not a two valve, I raced both back in the 70’s & 80’s I still have the 4 valve

1970's at Exeter"s County Ground. The noise, the smell and of course the dust and grit. A heady mixture if ever there was one. But of course it couldn't last and the rugby club sold the ground for housing and built a posh new stadium out of town with no room for the Falcons. Your video brought it all back thank you so much. I for one would love to see more of the old machinery on the speedway and the grass if possible

you did awesome

This ISN'T a 2 valve Jawa from 1971. It's a twin cam 4 valve Jawa from around 1980. Four valve engines didn't really exist in speedway until 1974/5 when Neil Street converted a 2 valve engine with his OHC conversion kit, ridden by Phil Crump, then Weslake engineering came on the scene with their phenomenally successful OHV pushrod engine. The carb would possibly have been a 36mm - although restricted 34mm carbs were in use in Europe in the early 80s. In German Bundesliga 2, a development league for junior riders, 4 valve engines were allowed, but with the smaller carb to reduce the power output and even things up, as many young riders were still using 2 valve machines with a 36mm carb. It's a DT500 4 valve I'm afraid...

Richard it is a 2 valve , special made for ice racing according to the owner

@@poweredbypies1 Take the rocker cover off. I used to have a 2 valve Jawa. An ex Ivan Mauger Engine tuned by George Wenn in LA. The engine here is a DT500. I know the difference as I had one of those too. If there’s only 2 valves under the cover I’ll be amazed.

Definitely not 1971, Jawa didn't make this double overhead cam style of engine until 1976. The model 894 and 895 in this casing were 4 valve, but the ice racing version was 2 valve.

@@iangraham1505 I think the two valve engines used for ice racing were the same long stroke engines used for long track before the 4 valve revolution.

It is a 981 2-valve ice engine. It was installed in junior racing dirt bikes and the bike was designated as type 980-3. It was three years in the making.

David, the engine is a 2 valve 891 ice engine, it has a bigger cylinder head and the screws holding the rocker cover on

Fajny filmik. Pamiętam dobrze dwuzaworowe silniki jawy. To była zupełnie inna konstrukcja i inna jazda od dzisiejszych maszyn.

In the 70's nearly everyone rode 2 valve Jawas as they were robust, fast and good handling bikes. In the mid 70's a number of 4 valve conversions came out and gave a definite advantage in power. Come the late 70's and both Jawa and Weslake developed their own four valve engines. The Jawa being a DOHC 4 valve and the Weslake a pushrod 4 valve. By 79 or 80 if you weren't on one of these, you were an also ran. Each had their own style of riding. The Jawa was a revvy engine. Gear it short and buzz the motor. The Weslake had a broader spread of power. I think the edge had to go to Weslake and by the early 80's the Jawa was fading fast.

I'm pleased you've experienced the upright and recognised the different riding style. It's the difference between a Meat & Potato and Potato & Meat Pie. Subtle.

I had a 4 valve jawa with valve covers exactly like that. In 1978. Large valve covers needed to cover...4 valves. They could rev forever

more reviews of old bikes please

You look to have got to grips with that. Next I reckon match race against Gary O’Hare on a Wessie 😎

Haha yes few more goes and I’ll take that legend on 😂

Did you ride it just the same as a modern bike or did you have to adjust your style? The reason I ask is because most riders back in those days used to get right out of the saddle on the bends with the left foot down on the track.

I'm pretty sure you're wrong on the date of this engine. It's a JAWA DT500 twin cam by the look of it and was first used on speedway in the second half of the 70s, the most successful rider on them being Ivan Mauger who won a world championship on one. In the early 70s only conversion kits for the old 2 valve JAWA engines were available to make them into 4 valves. The early kits being made by Reg Luckhurst and Neil Street. In the mid 70s Weslake came along with the first purpose built 4 valve speedway engine and they dominated speedway for the next few years until GM took over. I had 2 of these engines which I used on speedway and grasstrack. One of them was converted to 350cc for me by Cribby to use on the grass.

@@poweredbypies1 I'm pretty sure that big square cylinder head didn't exist until the mid 70s. 4 valve engines were used for a time on the ice but because of the different torque characteristics between them and 2 valve engines it was decided that for safety reasons 4 valve heads should not be allowed on ice racing. I could be wrong, but I didn't see that shape of cylinder head in any form of speedway until the mid 70s.

How do upright and lay down bikes compare handling wise? Nice video.

@@poweredbypies1 I had one & remember the oil feed digging in to the inside of my leg & the copper washer allowed oil to cover the right leg of my leathers. I had two 2 valves, I often regret parting with them. I can't remember what the DOHC was for, what it gave you that the single didn't. Anyone know ?

My mate was telling me that perhaps it is still fitted with one of those regulation throttle limiters all speedway bikes had back in the golden olden days. It was briefly implemented by the speedway control board way back then as a means to make the sport safer and reduce wear on steel shoes.
