As for the K2, the frame is useless, so I decided to throw it away. The frame above the engine has been cut. It seems that the cylinder head was rebuilt without lowering the engine. With this, the frame strength cannot be maintained at all, and it is in an extremely dangerous.

What lazy bastids!! Only takes around 30-min to remove engine anyway.

You can weld tubing back in. I've replaced sections of tubing from damage before. Trim off stubs in front and weld in entire new tubes. Use larger double-butted chromoly for higher strength and less weight.

Or you can wrap trellis ladder around both sides and remove backbone tube when done. Use Tange chromoly to be period and origin correct. Like how Ducati uses Columbus tubing.

K6 with K7 muffler HM405 and custom seat. The 1976 K6 frame and engine are matched with the original California license plate. Also the main, steering wheel lock, gas tank and seat can be operated with the same original key.

These two tanks are for K2 and K6 have the same external shape but different structures. The K2 tank has a bolt-on cock on the right side, while the K6 has a lockable cap and pipe screw cock on the left side. Both tank insides are good usable condition but the K6 tank has a dent that has been repaired with putty, so I plan to remove the paint and putty completely. Brown K2 tank seems to be paintable after sanding.

I had to order the oil pan yesterday. This is an example of "terrible" mechanic around the town. What I found was cracked oil pan at the drain plug which was enlarged and tapped,,,probably by 9/16". Common mechanic! Honda makes everything in metrics. An sophisticated owner of this bike took it to a oil changing shack in town. They normally use a power tool to release the plug bolt. Then ops, the aluminum thread was shattered. OK, know how is enlarging the tap hole and plug it with other plug so that owner will not notice. I don't know what happened after that,,, anyway ending was 14mm plug in the cracked oil pan. Below is the oil pan I ordered.

JFYI in case if you shattered M12 drain plug, the pilot hole diameter for M14 is 12mm.
You need 12mm drill and M14 tapping screw at least. If you really want to use inch scale plug, the 31/64" drill bit is required for 9/19" tapping. Other any wrong combination result like this.

There are many copy reproduction parts of popular bikes on the market. Of course, it's not as good as the genuine one, but it's fun as making a big plastic model. Attached is the one that has been spray can painted.
