Topic: HOW FAST IS YOURS ?

[Terry in Australia]

Older than time itself young Terry.
How are you dooing? how are the bikes coming along?Sam.

G'Day Sam, I'm good mate, was that inner ear thing true? The bikes are coming along fine, three running 750/4's, racer project ready to start as soon as I finish the K1, (just bought a neat steering damper and air shifter on ebay for a song) and am thinking about putting together another Suzuki GS1000S that I've got in bits all over the garage, but I might need a new set of big bore pistons to go with the big cams and 34mm flat slide carbs, woohoo! Have a good one mate, Cheers, Terry.

Keep at it Terry lad, but regarding the noise levels generated by the early Honda GP bikes I think the 5 cylinder 125 was perhaps the worst for doing ear damage, it was'nt a problem track side, it was the person pushing at the rear of the bike to fire it up.
The 125 had 4 lower pipes, 2 on each side and a high level exiting on the right.
As the bike fired up the revs had to be whipped up to around 18,000rpm and the pusher got a right blast from the high pipe.
Most of the factory riders suffer with hearing problems.
Tommy Robb who lives close to me  has hearing aids in both ears.
Jim Redman who I get to see once a year I think suffers a Bit, but riders of their day did'nt have ear protection like we have now.
It's great to hear these bike in the flesh, but look after you hearing.

My DOHC 750 was good for over 200 kmh - i never looked at the speedo past that - too busy
handling was a little unpredictable after 200

The Shadow will do 160 if pushed...

120 - 130 is fast enough these days though (most times)
Although, put me on a modern sports bike and... well - let's just say, there's reasons i don't own a modern sports bike

My Sons would miss me too much and there's too many rides left too enjoy

[Jeb]

Yes I can get it out fairly fast - depending in the circumstance

[Peterbylt]

186,000 MPS its not just the Speed limit, its the law.
 
With that said, the fastest I have ever driven my 75 550f was 120 mph (or thats what the speedometer said...)
One night on the down side of the Sunshine skyway bridge at 2am with a tail wind laying on the tank.

Fastest i have had the VF up to so far is 160 KM/H basicly..broke a ton on it. My roomate has done over 200 KM/H on the same bike. The CB still has to fire before it can go the distance..

[Terry in Australia]

Ooh ooh, I've seen 120+ Mph on my K1 in the last week, but as a disclaimer (in case my sons read this) I'm not proud of my irresponsible actions...............

120mph on 72 cb750k on I-4 by seaworld scary ride with strut bars. 110mph on the 1975 bmw r90/6 on the 408 not bad for a $500.00 bike with almost 82,000 miles on it

[seaweb11]

when your snot is running into your ears....that's fast enough

[siter81]

125 mph on my 87 punched out zl1000,it still had more,but i got smart real quick and let off the throttle?

Well I have not done quarter times or anything like that. Today though I went around a corner and gunned it and then shifted into 2nd. I hit 60mph in 2nd gear and still had not redlined!  I got there quite fast but decided to slow since I was in town in day light! This even with my battery issue!

You didn't buy that speedo from El Cheapo did you Eldy? Ha ha, just kidding, put that gun away mate................ 

[eldar]

Hey it was fun to play with! And no I didnt get it from cheapo! 

[Brent C.]

I had a 2000 ZRX 1100 and had it to about 145 before I started to run out of road...And my "new" 78 750 k I had to about 95.....don't want to push it.

[crazypj]

On my 550? around 126mph, ( panniers made handling 'interesting' between 115 and 120, after that it felt pretty stable)
 on newer bike? around 160mph.
Things happen a lot faster and you have to watch out for stuff a mile away( or more), almost hit a Merc doing around 125 when he changed lanes

When the CRs motor has a few miles on it, perhaps Chris will put it over a flyer.

Last time with the stock motor, it recorded 127 @ 9000rpm on the highest gearing we had. (18/44)

The motor was over reving at 9000 as it only makes power (60bhp) up to 8500rpm, should pull a much higher gear with the new motor. (18/39)   maybe

Sam.

[Terry in Australia]

G'Day Sammy, 18/39? I don't reckon you'll have a track in England long enough to get it out of third gear mate? I would have thought that on a race bike you'd be going for something a lot lower, like 18/56, so you can use all those extra revs through the gears? You're not taking it to Bonneville are you?

[Sam Green Racing]

Hi Terry, he would go into orbit with 18/56 (3.11)...thats the next gear down to what we are on now for the quarter 15/46 (3.06).

18/46 (2.55) makes it peak in 4th over the quarter at around 100mph.

It pulled 18/44 (2.44) at the end of a kilo at 127mph and it was over reving with the old motor.

I think with what I have seen of the new motor in testing (not been to dyno yet) it should pull the higher gear 18/39 (2.16) at the mile trap.

Time will tell...... Tell

Sam and others,

With a 90 HP engine and most of my riding being street with occasional trips to the 1/8 and 1/4 mile track and stop light to stop light blasts, what sprocket combos would you recommend?

Since I still won't be riding for quite a while (injury is only 25 days old), I have too much time to think about "stuff".

Sparty

[Sam Green Racing]

Ya going to have to figure that one yourself Art.

Chrises bike is 100lb lighter than stock and he weighs about 280lbs in his riding gear.

On 15/46 he has to slip the clutch a lot on the quarter and it peaks in top at around 100mph.

On the same gearing with the new motor, it's pulling big wheelies with not a lot of revs.

May be able to tell you more after the first meet at Easter, also, when we have had it on the dyno.

Sam,

How did you ever get mixed up with Chris?

[Sam Green Racing]

I was a mate of his older brother who came to race meets with me.

Chris came with him to watch me at one of the meets and saw a CR750.

He fell in love with it and asked would I help him build one.

I said yes and it ended up with him helping me

Never quite be able to get rid of him since

Oh, I thought that maybe it was a better story... like you fooled around with his mother.

Seriously though, good job taking him under your expert wing.  Mentors are few and far between.  I commend you.

I wouldn't say I was an expert Art, if I were, I wouldn't be working regular night shifts for a pitence as a security guard.

The only good thing about it is, I get to use the internet all night for free

Sam,

When I win the Powerball lottery tomorrow night, I'll move you to the U.S.   I'll pay you well to look after my bike and help me take it to the track.  You might also have to walk my dogs and wash the dishes and cook the odd meal now and then, but hey I haven't won the millions yet...
