1981 Honda Cb on 2040-motos

I built this bike for myself but after all was said and done I ended up buying a large shaft driven touring bike for myself. I enjoyed the project and I have a ton of photographs of the restoration and a ton of receipts. I give no warranty, it is a 35yr old machine and I am not a mechanic. I have restored many classic cars over the years and I found this project rather simple. Many original parts and shop manuals go with the bike. As the pictures show it is a beautiful classic bike. 

The reason I did a total rebuild on engine was because while I was addressing a slight head gasket leak and sending the head out to the machine shop, contaminates went down into the engine by my mistake. I decided to take the engine out and clean out everything. I found very little wear on any of the internal components of the engine which confirmed in my mind that this was in fact an engine with 13k original miles on it. This bike had to of sat inside someones garage for decades. The inside of the gas tank was pristine but the carburetors really did need to be totally rebuilt so I am glad I took it all apart to really get a picture of it's condition since I was rebuilding it for myself. The cylinder walls were pristine but I decided to hone the walls and put new rings in it while I had it apart. The main and rod bearings were all in good shape, the only thing I did was put new rod cap bolts in after inspecting the bearings because they should always be replaced when the caps are removed, (they stretch upon being torqued).

I also put new front and rear chain sprockets in.  The stock sprockets were 16 teeth front and 39 teeth on the rear. I put in a 17 toothed front and a 37 toothed rear sprocket which are allowed by Honda for this model.  This gives the bike more MPH in each gear with lower engine RPM's. Its like making it a 6 speed instead of it's original 5 gear transmission. This was a great improvement! I have the original sprockets for the buyer to show how little wear they have and the chain was in such good condition I just re used it.
