No, it's basically the Bandit600, Sv650, Gsxr 96 on cable set-up, but made slimmer so there is more room for a battery box.

cool the bandit worm drive thing is i bit better than the zed version as it has ball bearings in

let me know if it fits ok would sam be able to use the cad for it ? 

space is very tight down there i might go back to that type as it is pushing the fairing out on mine and i am grinding it out 

[HPF1]

Is that a fulcrum type clutch lever system you trying out Duncan?

I have just extended the lever arm on mine to see if it makes it a bit lighter

two years. 1996 and 1997.

Most of the 1997 I  checked  were injected so must have overlapped 

[A tale of two race bikes]

Had a Bit of luck i have been looking on the webike website for a set of fcr downdraft keihin carbs but they are quite pricey and then added possible import tax gulp

this is because I had almost given up hope of finding some used ones and the added problem is they only sold the gsxr srad 750 wt for one year with carbs before going injection route and i wanted to avoid buying some r1 yzf zxr etc and having to take them apart to adjust the spacing to my gsxr 

A notification popped up on a slingshot forum for some 39mm fcr carbs and the picture showed some downdrafts a deal was agreed and

6 days later I ve got them, very happy probably not enough time to set them up for my first race at Donington in three weeks but should be alright for combe in June

Coming on nicely now Mark.

Not looking bad is it thats the silencer that nine w managed to weld the ti and oil catch tank and a friend made some braided hoses for me I think he tests them up to 100 bar so should be fine 

[A tale of two race bikes]

Few more pictures of the bike with its clothes on the upper fairing brace still needs to be made and some odd spacers for the brembo rear brake torque arm and add the top stripe to the fairing

its paint not a sticker so unfortunately not part of the sticker kit and it would be a nightmare to fit 

The big race radiator first nicely inside the fairing and I won't bother with the fan 

I have fitted a cut away sprocket cover and some concentric swingarm bushes that allow adjustment the swingarm pivot position 

[A tale of two race bikes]

Had a bit more time to start getting the srad ready to race at first outing this season at donny and my sprayer  managed to speed up a lot and sort my tank

so following a bit of advice from dupersunc on how to stick it to the tank 

Now looks like something from blakes seven 

Carbs ultrasonically cleaned oil catch tank and electrics sorted tail unit down and stickers applied to the pearl white paintwork which was a pain to apply on the compound curves think I will get image works to do my spare bodywork

Did you find this thread?

 

that is that is the funky monk (Mark) billet one but only fits the gsxr 1100 g and h

How is this achieved?

i will see if i can get a picture of my old gsxr 750 slabby race bike but basically you have to use the gsxr slabby 1100 bell crank link and machine a lip around the edge of  the centre bearing (big) approx half way round it

also as this jacks the back up the arc that the crank now sweeps through will probably req a little grinding back of the lower cross frame support to the back lower part of the engine 

its only a little bit nothing structural 

the other alternative is to cut off the fixed dog bones on the swingarm and remount to jack the back up

the limit to this is if you move it too much to gain height the spring on the shock hits the s/arm

No dog bones on these.

1100 slabby linkage will raise the rear .

See if you can find a Funky Monkey racing linkage. I’ve not got one but I’ve heard good things.

@dupersunc, @KATANAMANGLER and @Mole28will be able o help with suspension questions on a slabby I should think .

unfortunately you cannot use the funky monk billet linkage on the gsxr 750 only on the gsxr 1100 mark did talk about making a new one just for the 750 but hasnt yet

there is a way of increasing the rear suspension height by approx 30-35 but you have to use a standard type shock ie 295mm long nothing longer as it wont fit or work properly

If a little long you may have to trim the dog bone a smidge. 

slabby is fixed and welded to the swingarm cant adjust the dog bone

Allways loved the srad endurance tails. What rad you using on the srad? 

Hi I believe the rad is from a gsxr 1000 Lo8 /9 so new model is also comes with a proper oil cooler the rad does require some mods

The Bodywork of my GS1000 was raced by Dirk during previous times. Also the swingarm was braced by him.

 

 

Old pic, but glad to see some friends of mine.....

In 2021 it is planned to have two events at Schleizer Dreieck. Can‘t wait....

Dirk did that swingarm as well its from 3 different bikes 

Although I think he is still trying to rebuild the yellow school bus

great write up....cool to see some more race prepped slabbies. will also try do the CSBK series not year, would be great to meet up.

Hi

yes would be good to meet up we will try and get over to a couple of the CSBK rounds next year with luck

i quite like Schliez and Oschersleben it looks lie spa is off the calendar until they start being sensible with what they charge the club

[A tale of two race bikes]

Hi had originally built big Bertha to use in Europe with German club i also race with and those rule allow more modern front suspension as the bike it in the open class

But since i am also able to race with the formula prostock club and ngrrc I had the problem of the front forks

I had already been using Maxton so decided to upgrade some gsxr 750 j k forks this meant the only original part is the cast lower leg as cartridges and longer stanchions now fitted

However I still need to sort some yokes and as the bike has had some many changes I realised that some adjustable trail yokes would be great best option luckily a friend of mine Donovan over in South Africa acc billet eng also race a slingshot and came up with these billet yokes they are really well engineered and am looking forward to trying them out 

[Racing Skoal Blandit]

are you booked in for following weekend with NGRRC at Cadwell i am up there but probably only on the big slabby

i seem to have dismantled the  srad already

Do you mind that’s the original gs/gsx engine

Yes. got a couple of weeks work. everything is still up in the air after that.

 

 

That’s good to hear hopefully it’s all picking up 

it looks like it will be ok for me and Dave to race with the German classic Superbikes championship this year so his 1200 will get an outing 

if we can find out what the idiot lights are I can pop some new ones in 

I have got the correct resistor to wire in for the fuel pump so I am getting some practice with the soldering iron
