Just wanted to send along a couple of pictures of the completed restoration of a 1972 Honda CT90 K-4 Trail Bike. Thanks to your site for restoration parts and diagrams for engine rebuilding my son and I were able to complete the project in about 2 months. The bike was completely torn down and all parts were painted and de-rusted with the electro stripping method. The engine was bored out 1mm over and new valves were installed. The bike runs perfectly and is now ready to ride in the Pacific Northwest Cascade Mountains. Dave & Mike PORTLAND OREGON @ Looking good
