bandit 600 fitting a GSXR 750 M or L series engine

[basha8991]

alright fellas
wanna go and buy an gsxr 750 oil boiler engine for my 600 bandit. the engine has 38mm carbs and is believed to be an L model. just need to know what i have to do to get it running. do i need any modifications or parts from the original gsxr like air box and loom.. thanks basha

Won't have to do too mutch, my mate is doing the same, i think a couple of mounts are different, you can use the b6 carbs, which might just need re-jetting. I think the wiring loom is compatable (can't remember)

I am doing something sort of similar, i am sticking a b12 engine with gsxr cams into a gsxr slingshot frame meaking a GSXR7/12. I am changing over the engine loom and carbs, but i have been told the engine fits right in without too many problems.

After all the b12 is just a restricted gsxr oil boiler big bored to 1200cc, same with the 600 is just a bored down version with diferent cams.

I think the B6 has a 6 speed box if i remember correctly. you can stick a top end off a 750 on to it making a gsxr750 with 6 gears.

Good Luck, Give me a shout if you are needing some advice if you go ahead, Ken

its far easier to change the whole engine over, the 600 as ken has said is just a sleeved down version of the 750, the mounts are the same as well,
the b12 and gsxr1100 have larger bolts at the rear mount and slightly different belly pan but are essentially the same engine as well,
the wiring loom is near on identical on the b6 gsx600 rf600 gsx750 gsxr750 rf900 gsxr1100 and b12

so you keep your old loom, chuck in the engine, plug in everything and away you go,
you can run all the engines on any of the cdi's but they have different rev limits, so the chances of over revving the b12 engine if you had a gsxr750 cdi in there, is there.

if you were to change cams ect ect, you have to pull the engine out any way, well you may as well chuck the 750 engine back in in its place and save yourself a whole heap of work

have fun, gsxr750 engines can be had for quite cheap as loads of people do the 7/11 conversion

if the 750 engine is a runner then save yourself a whole lot of unnecessary grief and put it in complete, don't be splitting engines and swapping parts when you don't need to ...

if the gsxr had/has an airbox on it before pulling the engine out then you might (most likely) need to rejet the carbs to get the fuelling correct once in your bike (i don't lnow if they'll mate up to your airbox)...

i believe the B6 has 32mm carbs, you say the gsxr has 38mm, i'd definitely get the carbs with the engine else it'll be strangled using the B6 carbs ....

you might want to get the GSXR cdi as well (i don't know if that will plug straight into your loom correctly so be very careful here) often oil cooled parts look the same at a glance but they aren't, you may find the B6 pickups (hidden behind the right hand case) are different to the GSXR pickups, so cdi's and pickups won't mix and match ...

the only ones "i" know will are the early gsx600f and the old gsx1100f as i've mixed them on my slabby 711...

i'd really suggest you get the haynes manuals for both the Bandit and the GSXR as then you'll have a lot more information to hand that you can reference accurately (won't give you cdi numbers tho or the pin outs )...

next tip, for one of the best sources of information on your bike/engine swap is for you to join OldSkoolSuzuki

check the thickness of the lower rear engine mounting bolt on both the B6 and GSXR motor as has already been said, one might be 10mm and the other 12mm, if you run the 10mm bolt in a 12mm hole then you seriously run the risk of breaking the mount on the motor, some folks put a sleeve in the motor mount lug to take up the slack, i drilled my frame to accept the 12mm bolt then made my own spacers, all other mounts line up nicely with no mods...

you might find the oilcoolers are a different size, i know the GSX600f cooler is tiny compared to the 750 slabby and GSX1100f cooler, it "may" run happily on the B6 cooler, i don't know, again i'd ask on OSS...

downpipes from the B6 "may not" clear the GSXR sump so you might need to swap the sump and oil pickup, you might need to just to attach the oil lines anyway, again OSS for definite answers plus the B6 downpipes have a really tiny bore in them so you'll probably want to change them as well to allow the engine to breathe properly...

750l or m is cable operated clutch ( i think), operated thru the clutch cover i believe, dunno if the B6 is operated the same, if not then get the cable as well....

the reason i keep pointing you to OSS is i've not done your conversion, so i have no "definite" answers

hope that helps, don't be put off, just get as much info as possible before you start pulling it to bits

it ain't broke...

i ain't fixed it enough

Oss is a good site, have already asked a few of the guys about this, they said you can change the top end of the b6 for the oil cooled 750 with a long stroke (F,G,H,L,or M models).

But hey all say aswel that it would be far better changing the whole engine over, and it would probalbly work out cheeper snd less time consuming.

I beleive the b6 downpipes should fit the 750, as they are round the same sized engines (1100, + 1200 are a bit taller)

The other option if you want more power is K&N filters, higher rated plugs GSXR cams, dyno jet kit, but if you get the 750 and do it to that you'l have an even faster bike.

One of the guys from my club is doing the same engine swap on his b6.

The L + M models are cable operated clutches.

Cheers, Ken

I have got something to make my own GSXR750 go a bit faster, Got this yesterday (only some of the kit pictured)
