This may be a dumb question...but

[Batman]

I would like to know if a 1989 GSXR1100 motor will fit into the 750 frame...has anyone tried this and if so did they succeed? Also has anyone got an 1100 motor if this can be done?

Chrz in advance

Yes it can and yes it has. Do a google search and you will find truckloads of info.

I don't have a spare GSXR1100 donk though

A mate managed to get an 1100 engine into a 600 chassis about 6 years ago. Even managed to get the plastic back on as well. There was a little bit of hammering needed to get the exhausts fitted. Very sneaky, great wheely machine.

Yep,and they'll fit into a 400 too......and yes,it's been done

Damn - guess it's a matter of time before someone tries to put one in a two-fifty now.

Now that would be a pre-89 machine...

I suggest go for a 900cc motor you can't beat a short stock motor cheaper too.
When they first came out they where quiker than the GSX1100WP yes you might say no but yes basicaly same motor just shorter stroke and plus there's to many different 1100 motors out there. So stick too the basics thats what I think.

GSX1100WP t/speed 161.4 1/4 11.08@126.6
RF900R.......t/speed 164.3 1/410.92@129.7

7/11 has been done so often its getting boring. Im sure thats where the japs got the idea for some of their new stuff from.
One interesting conversion is the fzr400 frame with a fzr1000 motor

[DEATH_INC.]

If yer just after more power,hang a turbo on that sucker....you'll get more go than an 11 and be more unique.....

Try www.gixxer.com as well.

It's real common and simple to graft 1100 engines into 750s but only between oil/air cooled models so far as I know. You'd want to do a bit of careful research about the practicalities of grafting a w/c engine from a later W series GSXR1100, or from an RF900, into a J model GSXR750. I suspect it might be a bit less straightforward 'cos you've got to accommodate a lot more plumbing. Anyway oil/air-cooled rules!!!!

I'd avoid the later oil/air cooled (1127cc) like L or M though ' cos they are a more fiddly with valve adjustment (buckets and shims) and run big 40mm carbies (lots of top end but at the expense of useability at low/mid range). Look out for an earlier series engine like F/G/H/J. There's lot of them around so shouldn't be hard to find one (although finding a good one might be a bit harder 'cos they've usually had a hard life). And tons of sources of performance gear.

PS Did I mention that I've got a J model 1100 (not that I'm biased ) with 142hp at the back wheel.......

www.gixxer.com not as good for old style stuff, good, its one of my othe usual hang out sites. But as long as you go air/oil 750 frame with air/oil 1100 motor you be sweet, and like kerry said tons of extra performance extras, and great to make a nice sleeper

Coooor Blimey,
1100's into 600 frames, Woof Woof

yup that been done as well, but the 600 gixxer frame not as good ast he 750 frame dc:<

Heard of a chick in the states that has put a busa motor in to her gsxr600, not thats what i call a sleeper a gsxr600 with 100hp and drop in a busa motor(with bit of work) puts out now 200hp now someone try smoking her, i think not, okay thing doesn't handle great thru the corners but alot of the yanks are in to that
they like straight line stuff

Yeah these 7/11 or 7/12 conversions are popular for streetfighters which are mostly (if I'm not mistaken) more about going quick in a straight line than anything else (oh..and looking cool of course). Everytone to his own, so no problem with that, but I'd be worried about the real-world useability of a GSXR750 with an 1100 donk in it. Quite a bit of extra HP (30-odd?) and those slab sider GSXR750s were pretty minimally engineered so I don't how how they handle the extra stresses associated with putting the extra HP down on the tarmac. The risk I guess is that you end up with a pretty unmanageable bike unless you invest in other stuff like frame and swingarm bracing, etc etc. Why not just go for an 1100 and if you want more bang spend the dough on cams, porting etc. Or am I missing the point?

You're right... It's a dumb question.
