GSXR1000 K1-K3 clocks on an 1100 slabside/blandit 1200 mk1

[Dezza]

OK, I need to decide which clocks are going on my project bike. It will have to use a digital speedo. The machine will initally have a Blandit 1200 mk1 engine until I get round to building a decent 1100 slabside engine for it. I want to use a cable clutch conversion with the 600 Blandit sprocket cover that I have been informed will work on either of these motors. If I use the 600 mk2 cover with the integral speed sensor, would this work with early GSXR1000 digital clocks? If not I will I have to use an aftermarket digital speedo with a wheel sensor so I need to plan for this prior to having my rear brake carrier made. Cheers for any input

You can use an aftermarket speedo with the mk2 bandit speed sensor. I have my Koso like so on a mk2 1200. It's easy enough (and wheel sensors look ugly)

To calibrate it, just multiply your sprocket ratio by 4 pulses/wheel revolution (i.e. mine is 15/45 so 12 pulses/rev) (if you're using the bandit 4 way crennelated sensor nut/pickup thingy)

Yes it will

I'm using a MK2 Blandit sprocket cover on my 1052 engine and K2 clocks on my EFE

You'll need the little pick up that bolts onto the end of the output shaft too.

Ok, that is good to know what I intended will work. I also did not know a Koso could be made to work with a sprocket sensor, although mounting a wheel sensor does not look ugly the way I do it, which is to have a bit of alloy tube welded into the rear disc carrier so the sensor is mounted a la Ducati 999/1098.

It may need a speedo healer though unless you’re running the same gearing as the K2. I’m running 17/44 and the speedo is wildly optimistic!

What's a speedo healer?

 think the old ones has cable to the front wheel

Plugs in somewhere to tell the speedo you've changed the gearing

K2 GSXRs dont

[davecara]

There ya go. I'm too cheap to buy one though, its more fun guessing my speed through gatso cameras!

I've got early GSXR600 clocks on my Mk1 B12, If you get the clock sub loom and matching connectors it can just be a plug in job.

Has the Mk2 B6 case got both cable clutch and speedo pick up mount ?

If your output shaft isn't drilled ( and some report it hard to drill if it's not ) there are ways round mounting the tigger.

The speedo is not optimistic , it's just a very good tuning mod. Instant 10mph more top end.

IIRC, the front sprocket nut from an 04 ZX10 can be used to trigger the sensor on the sprocket cover if using electronic clocks.

Why such tall gearing @davecara???

It’s just what I had lying about when I put it together! Seems to work alright!

i think its 14/48 on a slabside, and 15 front on a slingsht. ive just ordered an renthal 13tooth for my slabside

That's interesting, so the 1052 must have different gear ratios to say 1157.

Primary ratio is differ t but I think the box’s are the same and Just final drive ratio that different to accommodate the different primary ratio

Going back to the original point... ahem... Dezza, have you bought the clocks already? If not, it's worthwhile pricing breakers demands for secondhand clocks against retail prices of aftermarket clocks - and you may be able to get an aftermarket clock with more functions, better aesthetics and easier mounting for a better price.

Yep, I have noticed this. GSXR1000 clocks secondhand fetch a fairly high price. I think I will go with a 600 teapot tacho I have (10 quid from autojumble, really nice simple design, correct scale for an older 1100 engine) and a seperate Koso speedo/idiot light cluster (about 80 quid new). I can make my own neoprene foam surround for the tacho and it's oldskool gauge heaven.
