Well I guess I am hooked, I found a second cb 450 to work on, its a 1973 cb450 with 7900 miles on it and pretty good shape, plan to do another cafe but this time with a 350f tank and maybe go all red we will see. The compression is 178 on both, I ran it for just a minute when I picked it up and it ran fine, needs the usual tune up and carbs rebuilt. The carbs were leaking out the over flow and slight smell of gas in oil so I drained oil and cleaned filter. Filter did not appear to have been cleaned in a very long time and maybe only once at that as the Phillips head screws were pristine which is rare. I found some metal in the filter enough to get my attention anyway, and the o ring on the slinger was mangled, which is not a good thing, so here is my question to you guy's, look at the pictures of the cam and tell me if you think this is to much ware and I need to be looking at a rebuild, or should I pull the side covers flush the engine clean the filter screen, verifiy oil is going up top and just leave it alone. I change my oil every 1000 and clean filter at same time however with this engine I will probably change oil right away after a short run and then fill it again. What do you think?
