Re: Gpz1100 a1 crank
Number 4 exhaust at least, looks to have been running with zero clearance.
How do the shells in the cam caps look?

Re: Gpz1100 a1 crank
What does the micrometer say about the diameter of those bearing journals?
Mine look infinitely worse and i just polished them with solvol to remove the roughness. Not had a single problem with that as they still measured within spec and the oil supply side is very very good and it gets changed regularly. I put new shells in (repro ones) and thats where the problems arose for me.
With regard to the base circle on the number 4 exhaust lobe; again no issue with that as it should never (never again) contact the bucket. I would be more concerned with the lift and lower ramps on the lobe itself! If that is grooved then i would say you are done with them.
