Hi, think this seller had the 610cc conversion
 http://stores.shop.ebay.co.uk/Gremlin-Racetech
Well worth asking if he can help.

robrffr:
Saw on the net someone saying you can fit a CB650 crank, cylinders and head on a 550? To make 626cc? Might as well just fit a 650 lump isn't it?

matthewmosse:
the stud patterning is the same but not got a cb650 motor to try parts interchageability. the 650 has no kickstart I think. coils might also be different, plus carbs ??? Anyroad, if you had to remove the head and found the motor is a big bore conversion then sourcing a new gaskett might be needed.

duzatun:
yep mathewmosse
thats what i will be doing soon almost finished all the customising to a criuser major buffing all over been through just about everypart on bike and fixed what had to be fixed
 rebuilt forks as it allready had  longer staunchens wich are bushed on bottom milled legs to take what i think were RD 350bushes for top of legs and all back together better than new just example of type of rebiuld  been doing
 except for the head valves and bottom end and will soon do that but after all this work need to ride her around for a bit before i go into her internals
 i also got given a cb400f that had been laying  in a paddock for some years as  some parts interchangable the 400 had oil cooler on it in good nick as the oil filter housing on 400 and 550 are same part number the adapter plate in between the filter housing and crank case which the oil lines came out of fits straight on the 550 and the sml radiator in good condition too
and the link you posted for ebay i had alook very interesting will have to look into that further for sure

Correct, not sure about other differences but the 650 has electronic ignition (I suspect yours has points?)
