Bandit 1200 or GSX1200Y CDI unit

[T.W.R]

Which of either of these would plug straight into a GS1200ss ??

After spending a bit of time finding the idiosyncrasy's of the GS I've found the 8250rpm wall on it and it's damn annoying :brick:
I've found a few bits off-shore to improve other areas but hitting the wall at those revs in top I can only put down to the ignition advance curve of the CDI.

So was thinking the CDI unit out of either the Bandit or a 1200Y could eliminate this and allow the last couple of thousand rpm to be used.

finding info via the net is all but useless unless you know japanese :slap:

One has to ask, of course, despite using the same motor, why did they chuck such a low limiter on it?

Essentially it's the same motor but the 1200ss breathes through smaller lungs, 32mm compared to 36mm in the Bandit.

Haven't ridden a Bandit or 1200Y but going from a series of articles that I have on hot-rodding Bandits they rev through to 10k.

The 1200ss in stock form has the speed limiter at 180ish Kms but that is easily achieved in top at 6k, a wee additive to the wiring solves that but carry on to 8k and just a bit over it hits the wall, stupid really as it gets there way too easy.

Cheers TWR, The SS and the GSX Y, are a bit strangled compared to Bandit.
Get on Bandit .com and Maximum Suzuki sites and there is a heap of tips on Mods etc. But to get it to breath to ten grand you'll need GSXR1100 cams , a full system and a dynojet kit. Just a start for you !!!! Gaz.

Ha yeah I know they're strangled by comparison to the Bandit. But a stock gearing of 30km/h per 1000rpm compared to 24km/h per 1000rpm of the bandit is just begging to be played with.

I'm trying to utilise what's already there on offer without getting to carried away with excessive amounts of modifications. The way it hits the wall just sucks, it's definitely ignition related and I can easily balance out the fuelling to suit extra revs.
I've got the full "Operation Bandit" series which drew a serious amount of improvement in Hp without spending a lot of money and kept the bike looking pretty much stock.
If I was going to go nuts hauling a lot more Hp out of the bike I'd modify a stock head and throw a set of CRs on etc.

Until someone designs a decent exhaust system for the GS the stocker stays in place. Apart from a system I found on a Jap site everything I've seen just does sweet F/A for me, the cost of it was the equivalent $2650NZ without the cost of shipping :weep:.

Bill if you want something translated ive a mate over in Japan teaching and may be able to help,not sure how we would do it but a thought anyway,if you can email stuff to me i could send it on.

[AllanB]

Mine had the full titanium Yoshi system on it. It had no trouble running out to the top end, in fact I recall it being a good rush. I cannot vouch for the ultimate top speed as I never hit it. I suspect due to the tall gearing it may well get absolute top speed in 4th at redline.

Talking to other owners, even a can on the end of the stock headers made a big seat of the pants difference and a Southern chap claimed high gains on the dyno.

look for a yoshi can on trademe and have a muffler shop mend up a pipe to join the stock collector.

Thanks for the offer Mike, I've got a mate living in Kyoto who's married to a Jap. But it's venturing away from what I'm after at present :yes: just want to find-out whether the CDI from a Bandit or 1200Y will plug directly into the GS loom, once I get that sorted I'm going to start tinkering :innocent: though the ZXR is my toy for going nuts on :yes:

I've got a Micron can I'd slip on before anything else, just in my eyes all the Stainless cans just look like an afterthought.

Though thanks to coltnz I'm up to play with the appropriate mods to do; up the main jets from 95 - 115, richen the air mix slightly, fit a GSX1400 air filter and a can equates to just over 100hp at the wheel

Just us and them as far as I know, though they're a semi cult bike over there

My bandit pulls alot higher than that , do your carbs have tps etc like the bandit? there are ignition advancers (5deg?) made for them as well. From what I've seen you need cams done to get the high rpm horsepower, But kinda defeats the purpose why I brought it . after putting a modded can on ,it made a huge difference at the higher revs, even smoothed out the gear changes .

Yeah the carbs have the TPS unit. I've already investigated ignition rotors, their available from 2deg to 5deg and there's also an adjustable unit too.
I'm not chasing any major gains in HP yet, it's just clocked over 16k and I'm still having fun with the 98nm/3500rpm :msn-wink: when it gets a few more kms on the clock then I'll look at digging some serious HP from it.

There aren't any problems with the way it revs, it's quite free spinning for an old school donk but It's at the 8K mark it just hits an almighty wall and just defies everything the engine is saying prior to that point :brick:
and it's all ignition related nothing else.

[Mr Merde]

I have a set of GSXR 1100 cams ready to go into my GS1200 SS

Cost me $120 on trade me a while back.

Neptune do a can for the GS,

I'm looking at a can from the US for my bike.

Also looking at WP rear suspension e=ventually'


Have lost the fairing,, replacing the stock lights with HID set, Just bought a Bandit tripple clamp so I can set the seating position to a more upright one ( bad back).

Fightering the thing.

Have been told by someone else who had this bike that he upped the main jets to 125 and dumped the airbox completely and ran pods.

I've just dropped the front sprocket by 2 teeth and upped the rear by one. Pulls a lot harder through the gears. I'm not so interested in top speed as acceleration.

My bike has had the limiter over rided. If you search the site there has been a number of discussuions over this bike and I seem to remeber someone saying how to disable the limiter.

Unfortunately the stock instument dont read over 180 kph but at that speed you dont really ndeed to know what you are doing. If caught you are fu<ked whatever.

Have had my bike screaming at 10,000 rpm but with the tall gears I ran out of roafd by the time I got there. hence the gearing change.

PM me and I'll share a little of what I have discovered abbout this bike over the past 2 years and 90,000km of riding one

:rolleyes: Everyone's missing the point of the thread slightly.

I just want to find-out whether or not a CDI from a Bandit or 1200Y will fit.


The GS has the 180km limiter disabled so that isn't the issue, it pisses over 180 in 3rd-5th gear.

It revs out cleanly in 1st-4th but in 5th at pretty much bang on 8250rpm it hits the Wall, it isn't bogging or leaning out.

I'm not interested in what it'll do full tap and couldn't be bothered investigating a figure in a straight line. It's got enough porridge down low to loft the wheel easily enough & break the ass-end out when I want.

I just want to rid the bike of the issue coz I've found it, know it's there and it's annoying:brick:

I'm not interested in digging in to hauling vast amounts of HP out of the thing yet, the ZXR is my toy for fucking around with in that respect and it's currently lined up for a wee pile of items as it is.

When the time comes for chasing the GGs I know what I'll be wanting & where to get it.
The majority of slip-on that I've seen fitted to GS's all look like after thoughts IMO irrespective of their abilities to improve performance most look gaudy and if I was to put something on it'd be this below, it's minimal, snug, & has a clean balance in keeping with the bike's lines

Should just rape one of the next Bandit I see unattended :shifty:

Staying on ya question twr , ridden a gsx1200y , didn't seem as perky as the bandit at higher revs .If it was me I'd be lookin at bandit cdi. Bandit has gearbox ignition retarder too im told , is there something like that on the GS?

[homer]

not a mechanic , but the bandit 1200 pulls out to 11k thats red line .
also a limiter at 260km/h so ive been informed.and it pulls 8500rpm at 240km indicated .
4 th gear will pull 205 easy indicated and i think theres still a bit to go before red there as well .
also no good going over the red line as this will possibly melt rings .
the max hp and torque kicks in at 6k so really going over 7.5k is quite a waste of time .
just some usuless information.

I'm not sure about the 1200Y but with a bandit having the lower gearing compared to the GS if there is a gearbox ignition retarder system in place then as they both pull a top speed of around the 245km/h mark then a Bandit one should allow the GS to rev out further.

Though I've delved around a bit and a Dyna 2000 DDK33 ignition unit will fit ;) 5 mapping programs etc but to utilise the unit fully a set 2.2ohm coils and leads should be used.

Also found this too which makes the addition of Yoshi bits a bit pointless.

Pre 99 bandits are where I'm looking at getting a CDI from and the technical data I've got uses a 97 model as the basis of their tuning efforts.

The GS makes 100hp at 8k rpm so that's basically my bug-bear issue, having it hit the wall only a fly-shit above that is stupid and I've never had a bike do similar before.

That should be interesting Mike, the wee buggers have some stupidly hot-rodded GS's floating around over there but just finding a bit of a mild scenario to cure the issue will suffice.

On a side note here's a bit of what is to be done to gain a peak HP of 127hp at the wheel on a Bandit:

107.5 main jets (up from 102.5)
40 pilot jets (up from 37.5)
Suzuki race kit needles (from a GSX-R750RR, better than Dynojet needles)
GSX-R1100L cams
Yoshi igniton advancer (4deg advance)
K&N filter
GSX-R1100L airbox cover
Skorpion muffler

Made a 29hp increase over stock and a 11hp increase over a Dynojet kit that they'd previously tried in the bike.

Spoke with a friend yesterday TWR, He has my old bandit and an SS !
He was of the opinion that the CDI can't be used and that you will need a thing called a TRE which is I believe a de restrictor device , He has one on his Busa as well ! (yes he has a shit load of bikes !)) Hope this helps ? Gaz

Thanks Gaz,
But a timing retard eliminator hasn't any effect on gears above third, basically in plain english a TRE fools the ECU to thinking the bikes in a higher gear and thus increases the voltage & resistance drop that the GPS (gear position sensor) signal delivers to the ECU.
In 5th gear the voltage & resistance are roughly 4.25v & ~6500ohm whereas 3rd & below are 2.9v & ~1500ohm and below.

The GS hasn't got EFI so doesn't have a ECU :rolleyes:

Though I might just do a diagnostic on the ignition system to check if there is any significant loading or lack of on it at different rpms

:niceone: watched it with interest at the time it was current. Silage (ex- Jimmie) brought his bike from my mate so I sort of knew it before he did but know the ins & outs of disabling the 180km/h cut-out ;) that was a first thing to do when I got my one and I pointed the wee device out to Silage when he came around work a while back.
But I'm trying to eliminate what Silage actually mentions in one of his posts in that thread ;)

sorry to thread dig,

did you ever find the answer? If not , and you're in auckland i can whip mine off i have the gsx1200Y and test it

and...did you do anything to the carbs? i run the same carbs and wondered wether it's worth looking at mine or getting some bandit/gsxr1100 ones.

BTW my motor limits at 12.5k - looking at dropping my front sprocket a bit to give me some acceleration. Not that I really need it.:Punk:
