If you have decided to replace the head once you find one then you have little to lose by modifying the existing head.

Obviously if the head proves to be so impregnated with oil that welding is not an option, you could try for some form of screw in or bolt on interface.

DSC00001 (6).JPGFirst day 03-19-13 001.JPG For me it was look good and be able to ride safe. Changed the rims, put some paint on the rear fender. Powder coat the foot pegs. Rebuild the engine, change the seat, put some wax on the tank & frame. Leave the patina to the Pickers. When you are riding yo...

This is a pic of my son's R60. The engine has been done up with a new crank and pistons and now runs fine. He has gone the line of fixing up bits that need fixing but not making pretty things which are quite serviceable. So I guess his road is the middle road. If however a person was to procure a bi...

Look for what it worth, here is one idea and probably not the best one by any means. Given the head is pretty sad there may be worth the risk of modifying the head to match the header you have. If that fails then plan B is source another head. What I would do is check to see how much metal you have ...

Hi Mal, Oops.... I meant to include the Sunnen part numbers of their portable mandrel drivers for your review. The P-180 and P-200 are the units to use in this application. The initial upfront cost of the tooling usually is the reason not to take this process path. Yet, it is an excellent tooling a...

For the lifter bushings.... An adjustable reamer is not efficient or accurate in this application. A reamer that is to the finish size diameter is also not that efficient or accurate in this application. One issue with using reamers is their ability to ream to size. Most often than not, the reamer ...

Battery box is a bit big for the bike, but I have learned some things which will come in handy.

Hello Mal, I am very much enjoying your posts. It's enjoyable to learn from other mechanics, and you are doing such a fine job of it. One little tip I'll pass along, in case it is helpful to you. I do not align crankshafts using two v-blocks, one on each main bearing journal. Rather I use two v-blo...

I am sure many of you run into this problem. The bike is sitting neglected because I have all these other tasks I have to undertake prior to being able to focus on the bike. So there has been no progress with the bike because as you can see I have been using the workshop to do other stuff. MAL_0934....

Couldn’t find proper stud spacing from the multitude of Mikuni Adaptors. Closest fit was from Oz (Australia) and required pulling carb head mount studs and had a 28mm throat at the mounting end. The head opening on my R60 is 26mm. Maybe a step is not too bad but smooth is smooth, so my design is 26...
