The engine in this thread is a CB500 Four and not a CB550 ;)

So I am starting the re-assembly of Lazarus's engine and have rebuilt the gearbox and now fitting the crankshaft. I have a problem with number 2 big end journal, when i fit the con rod it feels tight and a bit notchy. I have new bearings according to the numbers on the crank and rod, and have tried both green and yellow with the same effect. Looking at the shells they seem to rub near the joint between the main rod and cap, i have the rod the correct way round according to the manual and the crank pin looks good unless it has gone oval? i dont have any measuring gear to check so not sure what to do next. This bike is fighting me all the way!

When I had a high spot on a conrod after fitting my casings together it turned out to be oxidation / oil tarnish on the bare con rod. Cleaned them up using a light rub with Duraglit.
Were your conrods nice & clean where the shells sit? The tolerances are very close on these Hondas.
