GSXR Bandit.

[Jocalopse]

I've got a pre '93 1157  GSXR and a '05 B12, which also says 1157, are these the same engines with the only difference being  cams or is there more to it than that?

Pre '93? Didn't think there was an 1157 before 95. Sure its not an 1127? Whats the engine number prefix? It'd help i.d. the motor. 

[Foz]

Clutch,cams etc are different. The last of the oil cooled gsxrs were shim heads as opposed to screw and locknut adjusters . 

[Jocalopse]

my mistake, it's the last gen oil boiler 1100 before they went water cooled and an oil cooled B12

 

[Jaydee]

As Foz said, your 1127 is has a bucket and shim head(M/N). Shim heads have different cams and valves than locknut 1127/1157 heads. 1127 K, L, M and N's use a conventional timing chain whereas 1157's have a hyvo timing chain. 1127 and 1157 cranks/cam wheels differ to suit respective timing chains. 

Have a look at 'Frankenstein's guide to oil cooled engines' Plenty of useful info to familiarise youself with oil boilers.

no buckets in the M/N head, they came in the waterboilers.

[Jaydee]

Think I had a bucket on my head when I was typing that C.C.

The engine number will tell you what bike the engine came from (sounds like someone swapped engines) - last OC GSXR engine as JD and Capt have said were 1127, which have shims sitting directly on the valve spring retainers.

Look on the barrels it'll say either 1127 or 1157 - saves taking shit apart?

No quite, all gsxrs had 1127, bandits had 1156 on the barells  in 1995 on preproduction models, when they came out officially in 1996 the small panel was left blank for some unfathomable reason,

Performance wise the Bandit motors had the less aggressive cams and lowered compression from the GSX1100G . Essentially it was a slightly larger, chain drive version of the 1100G shafty. Which itself was essentially a detuned shaft drive version of the 1100 Katana. That is kind of why putting GSXR cams in a Bandit is a good low cost mod.

we call those things Powerscreen.

The 1100G also has a balancer shaft.

Some production models have the capacity on the barrels. A friend of mine had one.

Interesting, ive never seen one with 1157 on it, you learn something every day here

Is there a better gsxr can to put in a bandit1200 ever one of the 1127 or one of the 750 or are they all the same? May as well ask as some one is going to. Lol

Are we really kwibbling over 1cc? Whatever if its a big motor it'll either say 1127 or something else! LOL

[vizman]

there's no kwibbling over facts

[Jocalopse]

well, well, well.......it's almost like I asked which oil or tires are best for my new to me Bandit, it's brought everyone out of the woodwork. Anyhow, the Bandit is still at the dealership I'm buying it from and there it will stay until the weather improves, I am in Canada after all. So it is a last generation oil cooled GSXR1100, whatever was sold here in Canada and a 2005 Bandit. The reason I was asking is the B12 has 60,000km on it. I had planned on maybe rebuilding the GSXR engine, then swapping them, giving me a refreshed engine in the B12. I can't put the GSXR on the road, as someone filed off the VIN on the headstock, we all know what that means. Anyway it's complete, but in rough shape anyway. The tentative plan, I don't want to be without a commuter as the XR650 is hell on the highway, is rebuild the engine for eventual swap, and maybe swap the front end as well, maybe shock if possible and worthwhile. Was really just enquiring as to the relative similarity. Pretty sure they have the same engine mounts.

 

[vizman]

inside or outside?

[Jocalopse]

inside or outside what? 

 

[vizman]

were you after the interior or exterior differences between the engines

[Jocalopse]

outside I guess, just need to know if I can bolt the GSXR engine into the B12 frame using all the stock mounts and spacers, and mate it up to the stock inake and exhaust with no major surgery.
