GSXR750 bandit1200 dot head

[Otatts]

Hey guys I’m new here. 

Been reading a lot here about the bandit1200 with the DOT 750 head (both of which I have) but most of what I’ve read is about fitting this engine in a bandit 1200 chassis.

Question I have is will this engine combo fit in a GSXR750 second gen frame?? Has anyone here tried?

Ive already got the bandit 12 motor in it and it’s a tight fit. Read the intake angle is steeper on the DOT head so carb clearance might be an issue??

Cheers O

Tight is good!  A DOT head from an 88/89 GSX-R 750 or early GSX-F has a raised inlet (appr. 15 mm at the carb rubbers). Either head, it will fit your frame, but the filters may be slightly deformed. Foam filters on trumpets will work fine. 

It's been a long time since I fitted an 1127 into an 88 750 frame but I remember that I had to replace the petrol tap. I bolted a block to the tank with the original two bolts, and fitted a 90 degree elbow and a 1/4" ball valve (teflon ball) to the block. Some people raise the rear end of the tank slightly to solve the clearance issue.

Thanks for the info Nik! I’d read the fuel tap clearance was an issue with the bandit frame so I thought there’s no way it’ll fit in my chassis! Was just tying to get an idea before attempting to remove that motor again

cheers man !

Yes , had a 750k frame fitted with 1200 bandit and 750k dot head and 36mm bsts. Ram air filters and stock bellmouths. tight fit but no trouble.

Thanks dupersunc. Did you also have to move the fuel tap? It sure is gonna be tight in there!

Spaced the rear of the tank up 12mm.
