92 GSXR 1127 engine into 750F Katana, [sick]

[Buffalo Bill]

raw power?

Brought home a big lump, said to be running before X.
Came from another guy's donor bike: 92 GSXR1100. I saw what's still available, frame with swing arm, most of the body panels, front and rear wheels, complete front end inc calipers, all very nice.
The 92 GSXR 1127 has the highest lift cams in the Haynes manual, "Ooh, scary stuff kids!"

Well I can begin taping the body anytime and get the painting done.
This is my track day bike, so I need to do the engine swap between track days, the 1st week of August works best.

Been doing hours of research about the carbs used for the different years and bikes using the 1127 engine, looks like I can use the existing carbs modded with a Dynojet kit, because they are the same carbs used in the 1990 GSXR1100 rated at 143HP.
Bought clutch lever with lines and slave cylinder, oil cooler with lines, Katana 1100 exhaust complete, and will pick up a 1992 GSXR 1127 this Saturday.
Will post picks of it all together after it's all collected.

Here's very cool link I was turned on to, over at katriders.com.
It's an automatic gearing/sprocket calculator and has many bikes in it's data base.

My kid would like to find a cheap one with good bodywork on it so he'll have spares. He really loves his, he's got an '04 1000 grudge style drag bike too. I'm putting in to my '83 what you're taking out of the Kat. Slow going, had to motch the bottom of my fuel tank and move the petcock due to the height of the carbs with the dot style cylinder head thats on those engines.

I've already done the rear wheel swap for the post 98, and got a 160 radial in there, real nice.
When that's worn out I can fit a 170 in, but looks like I'll have to wallop the caliper arm, bend it a might to fit the 170 tire.

This bike only cost me $470 back in 2011, so I'm probably still under $1000 spent.

That cat looks stoned..... (subscribed)

Do you have the stock rear wheel on the kat yet? The rear wheel from a post (2nd gen '98 and up 600 or 750) will swap right in in and will allow a 160 tire, only drawback is that it has straight spokes. We put one on my kids '90 600 with a busa front end.

Looks good and probably a damn site more comfy that that GSXR.

He's easy to bribe.

Ill be following along with interest. Good luck. The cat approves?

[Buffalo Bill]

I dunno, getting blown away by the liter bikes on track day? I need to fix that.
Seems it's an EZ swap, putting a big 1127 into my 750 Katana, because the blocks are identical.
Already promised to buy a 92 GSXR 1127 this Saturday, KILLER.
Bought a complete Katana 1100 exhaust system this morning. Could not pass on the price $25, WOW.

Not gonna publish endless pix of polished nuts, and bolts, (I hate that) just a few of the important bolt ins, still dirty and ugly.
Suzuki's gonna do all the engineering and fabricating, I take no credit for that.

Will be painting the body too. Here's a photoshop redo of what I have in mind, I wanna copy the 91 GSXR1100, but in maroon and charcoal, with silver accents.
