I have been gone a while due to moving, getting a new job, and all related frustration, but I have made some headway on my engine rebuild. I removed the head and stripped it down. luckily the head and cylinder walls look quite good for a bike of this age. I'll have to hone the cylinder as it is glazed, and replace the rings, but I don't think it needs to be overbored, wich is good, because I can't find an os replacement piston anywhere. the head has cleaned up nicely, but I found that the intake valve is damaged and needs replacing, along with the valve seal. I will probably also replace the exhaust valve seal just in case. I'm not sure if I can do the ceramic coating at this time, as I'm not sure it would take to the old dirty parts. I might do the exhaust port though if I can get it clean enough. I have decided to use an extra thin head gasket to get a little higher compression. then I will get the cam as close to stock timing as possible erring on the side of slightly advanced. I am trying to spend the smallest amount possible on all this, so that I can afford to replace the carburettor with a fuel injection kit. it's a $400 mod, but would allow me to map the fuel metering precisely for max efficiency. Alternately I will buy an AFR meter, and every available jet for my carb, and go to town.
any comments/suggestions?
I'll try to post some pictures of the cleaned up engine, as well as my mods soon.
