1990 GSX750F Engine swap

[shadowfax]

Asking more out of curiosity than anything else. 

What motors will  go straight in within the minimum of work? I believe a bandit 6 will but that's too small/slow, so 750 or above? 

[Swirl]

I put a gsx1100f power screen lump in mine, straight in used the 750 breather, removed the tank support, using the cable clutch for now, so if that goes in, any oil cooled motor gsxr 1100, b12, gsxr 750, b6, gsx600f will fit

[shadowfax]

So you would need the engine and its carbs? what about electrics, coils, ecu?

[Swirl]

I had the whole bike, used the 1100 carbs, 750 loom coils, 1100 cdi just plugged straight in, all the 750 stuff and 1100 loom is going in my kat, best trying to pick up a while bike and break the rest, 1100 power screen I would say the cheapest to pick up, the dot head 750 is not much short on hp of the gsxr 750

[Swirl]

you need the 1100 exhaust too

Or swap the sumps and pick up and tube/s

[suzook12]

Choices are 748, 749,1052,1127 or 1157

You can use the gsx750f carbs on any of the oil cooled motors just used the gsx750f carb rubbers as well.

I know the zorst of the 750 will fit other 750 and the 600 but the down pipe's are shorter than the 1100 and b12 ones, but never tryed swopping the sumps etc.

Had yours gone bang? If so and its got a DOT head get a b12 motor put the DOT head off your 750 on it and have some fun 

[Swirl]

yes need the exhaust, 7fiddy to short for the 11, I've been out on mine this morning but I've triked it to(knee problem) and it flys, if its the original motor it will have a dot head

[Swirl]

got a weight cert this morning, 280kilo, just slightly more than a powerscteen so you can imagine how it goes

[shadowfax]

Well, done some more investigating and the cams are pitted, probably due to 2 washers on one side and none on the other making it run dry. The existing fuel filter was horizontal and the pipe was a little kinked so got shot of. The air filter, don't think it had ever been changed, looked clean on one side but the other .... errr no. Done the valve clearances, balanced carbs, new plugs and she is running so much better. Think I'll wait and get some more miles out of her. The other half was in mourning as she thought she was going to have to go ............... the bike otherwise known as Delilah (cos she is mine mine mine Delilah)

Can I fit GSXR 750 WR front forks to my 1999 GSX 750 f ,. I wasn't sure about the length ,. 

[wraith]

Will need much more work, as it's a water cooled motor. The good bit, you can make a cuppa anywhere

Short answer "YES"

Long answer... yes but you need yokes, wheel, discs, calliper's spindle and speedo drive, they are long enough as I have 750 L front end on mine, same length,  and its fine, maybe even a bit long, im going to drop mine 10 mm to aid turn in..

Late to the chat. I have a mk2 gsx750f, some point down the line I'd like to stick a gsx1100f engine in with down pipes. I'd plan to stick with the 36mm carbs and 750 intake boots. It looks like someone who posted on here jas done this, I'm wondering about carb jetting? I understand the gsx1100f has 34mm carbs so I'm not sure if the stock jetting would be appropriate.
