I have fitted ZX10B engine into a ZZr1100C chassis as i dropped the ZX and got a good deal.Thing is i've had to use the ZZr carbs and air box.What problems should i be on lookout for.It's 98 per cent together and ?turns on key :unsure:

Using the semi-downdraught carbs from the ZZR - can interfere with the frame or the petrol tank or gas tap - so check clearances.
Other possible problem is getting the jetting set up correct.
Other that these issues - should be good.
