Hi Gents,

I love these threads going in 3 different directions.

It's really very simple. Two-Strokes fire every time around. Four strokes fire EVERY OTHER time. It takes a 4 stroke of TWICE the displacement to equal that of an Two-Stroke (powerwise). Forget about the fact that the Two-Stroke (of half the displacement) weights much less. Technical progress?

Start a 250cc (whatever displacement) WGP class.......NO ENGINE TYPE LIMIT. The winner will be on a Two-Stroke.

I doubt it Don, I think a rotary would win Ask Herr Wankel He'll put you right.


David

Now David,I can make enough shit,without you helping me Any-one got a shovel?And in any case the ruling tossers would handicap us by a factor of 1: 1.7,,cos they are scared of being thrashed if they put us wank(el)ers on an equal footing capacity wise!
H the W

Rumbled eh? well anyway the Norton had no money in it and it was a missile



David

yes all very sad, i still think of it as my sport going away from me, im sure the rule book says that no one can ride 2 classes in a day in moto gp. the 4 stroke mx bikes sound terrible, cant stick them. sound like a c90 with the exhaust gasket split. all set up now so that joe blogs can channel hop on sunday afternoon and come across the drivel that comes out of that cox/parrish duo, think that the stifled procession he is watching is amazing and be told that rossi is the best thing since ever! even though he has never seen a bike race before, then he will pass his test and get one of those superbike clone thingys and thats it, watch moto gp on the tv where the hoard of celebs that appear on the grid all seem to come out the same line like its drummed into them "always been into bikes" even though youve never seen them before or since. 2001 and 2002 were very diff years at donny, i never went back after 2002, very sad for me that honda won the last 500/250 championships, then lost rossi cause they wouldnt give him a certain bike. sorry to keep going on or if ive upset anyone but something has stopped, whether it be from the bikes or the characters that ride them? i am a die hard 2 stroke fan and obsessed with 500s, theres just less and less to get up for now on a sunday. you watch a bsb/ss/wsb bike live on track and no matter how fast it is, its still a road bike with the lights taken off it, do the same with a 125 rs honda or the like and you know its a race bike. there is a difference. they made the big mistake of letting wsb be a world championship, should never of happened in my eyes, should have been a world cup god im getting old and grumpy

Hi Phil,
hows it going ?
Agree with your sentiments, always loved racing the two strokes, my RG MK7 was a great tool, just a bit of an eye opener after riding 1000cc four strokes for years !
Remember the first time i rode it down the industrial estate where i worked and thinking " how can a human ride this thing, its like a switch, nothing and then Oh my GOD as it stood up on the back wheel in 4th gear !" Once i realised it was all down to clutch control and keeping it in that tiny little powerband all was fine!
Was lucky enough for my sponsors to buy me a brand new reverse cylinder TZ250 in 1990 and then a V twin RS250.What great little bikes, completely vice free and made you carry so much corner speed that your riding improved ten fold !
Easy to work on, remember the TZ did a crank in first practice at a North Glos meeting, we had the crank changed before the first race and the engine cases were still warm when we had finished !
Like you i am looking forward to Moto2 and hope that it produces the sort of racing that Moto GP needs, will miss the 250`s though, they produced some of the best and closest racing of the last decade !
Happy days !

Just found this page (only page one) from the qualifying to the Swedish GP 1982 in my box of old stuff.
29 riders within 2.84 seconds, different bikes like Yamaha, MBA, Pernod, Kawasaki, Bartol, and Rotax powered bikes like Kobas, Armstrong and Nico Bakker.
Close racing different equipment, good old days (still looking forward to next season of moto GP though).

Cheers,
Leif

Yes interesting that Leif, I seem to recall that at the last 250 race this year, William Dunlop was 6 secs slower than pole, possibly showing the need for change because of the haves & have nots! IMHO. (other regular 250 pilots 4 & 5 secs slower too, before some of you cry it was his first GP).

..... and eleven frenchmen in the first 29 spots ! How have times changed


Oh, and by the way...... nice position for you on that grid Leif

And they say the times are closer today? Mmmmm....................
Some really good names on the bottom half of that list. Dear me, how strong was that field then? Really impressive.
Anyone have any idea who won that one (without cheating now ). The podium would be nice.
How did you fare in the race Leif? And what about our Jeff. Surprised to see him down there, but I suspect a bike that wouldn´t behave?

Hi,

1982 was a pretty good year for me, I really liked the Nico Bakker Rotax, I can’t find the result list from there, but I think I finished somewhere between 15th to 20th.
Mugello and Hockenheim that year were pretty good for me too, and in Brno the ignition stopped working during the race.
A few years ago I found the bike again, and I am slowly (very slowly) trying to get in running order, hopefully I will be ready for Spa next year.

This is how it looks now:





As you can see, still things to do, biggest thing will be to make new exhausts for it, that’s quite a big job

Cheers,
Leif

Beautiful Leif. Keep us posted on the progress.

Looks great Leif
looking forward to seeing it when you have her finished

When the 500's went away I stopped watching too.

Back to the days of 50, 80,125, 250,350 & 500 and the sidecars,I think many will miss those screaming 2 strokes as I do

That just about sums it up for me too, welcome to the Old Farts Club mba21

Welcome MBA glad you came to join the fun! Been taking a look at some great photos of Corrado Tuzzii thanks facebook!

Going to bed now. nite nite


David

Here is a pic of my old mba,the frame was built by Roland Broadbent a local guy to me in Oxford it was a beauty and a joy to ride, the swing arm was nickel plated,and the mono shock was from my old TZ 125,so if any of you guys no where it is I would love to get it back the frame was stamped on the headstock RJB 012. I sold it to a guy who i think was starting up collecting race machines Steve Griffiths. whoooops how do I post a pic in here but this was my old machine that roland built for me

Welcome to the Forum , MBA 21 , may your stay be long and enjoyable
Someone cleaverer than I will probably talk you through the posting bit although I can post , the technical side I find !!!

Lovely bike!
Welcome

Well I shall miss the 250's, just as I miss the 50's the 80's the 350's the 500's the Sidecars!! How do they think that a road bike can take the place of a properly developed race bike. We had close racing in the 70's.............untill they either dropped or ruined all the decent european race tracks. We had 7 good races to watch in one afternoon, now were asked to pay £50 to see 3 races and load of marketing. I haven't been to a grand prix now for about 10 years, it's just not worth the effort or the money. And what happens when they eventually drop the 125's because no manufacturer is building 2 strokes anymore...........wonder what they'll replace that with

Maybe it will be Moto3 using CBR125 motors in trick frames.They have a CBR125 series over here in France for the fledglings,so it could be a 'tryout`.I,m getting depressed thinking about life without 2 smokes.Time to uncork a bottle of 1€ Merlot to dull the pain!!!!!
HW

I promise that I'm not being mischievous - what I wonder is the theory behind the steeply angled seat ? Late model TZ's too had a similar riding position Didn't it put a lot of unwanted extra weight on the arms, not to mention the ol' wedding tackle wedged against the tank?

And I've already had some Yes and whether you like the 2 strokes or not, it's just a different sound. One of my mates summed it up after a visit to this years TT. He said, you just wished there was a 2 stroke coming down the road, all the races looked the same and sounded the same

To be honest i never really noticed it,this bike was just great to ride the position was perfect,as were the really angled bars,ermmmm the ol wedding tackle is still in perfect woking order !! even now

Stops yer arse from sliding over the seat hump and off the back.

Now that WOULD be bad for the wedding tackle I reckon.

Damn powerful them stinkwheels were, Russell.

Gerry Mobey from the Marlboro series went to Italy with his dad and picked one up back in '86 and I never heard of him racing it ever. They were pretty expensive at the time as far as I can remember. Did they make these in Pesaro?



David

spot on, the best feeling ever was waking up in a campsite at 7 in the morning and hearing a 2 stroke getting warmed up you always felt you were missing something!! and if anyone hasn't heard a 2 stroke sidecar, well you missed something special, awesome

And getting the smell wafting over!!
I used to arrive really early at Brands/Snett before the bikes were allowed to start up, and then hearing them crackle into life, the hairs on the back of my neck used to stand up, and the smell drift across to Druids or Corams....luvverly!!!

Hi All,
The sight, sound and the aroma of burnt bean oil will be around for years to come.



Don

Very smart Don , what's your next project going to be ?? any idea yet ??

Hi Phil,

Thanks. Next project......not sure yet, however you can be sure it will be a Two-Stroke and more than likely it will be all white with a big red stripe down the centre.

Don

Oh , thats a shame , i've found a Schirtfinkle
