Is this a new "Milwaukee 8" motor? They had to take some weight off the counter balancers, it was too smooth in beta testing.
Not sure Gary - it says “107” on the RH engine intake cover which either the displacement or the weight of the shifter mechanism in pounds.
Hate to get off topic and not talk about Harleys here, but I did a little work on the 1978 XS650 today.
And when I say little I mean it. The other day I was tracing out some wires on this bike that had been what I would call an experiment for some high school kids in a mechanics class at local tech school. I was using a small 12 volt power source to check the lights in the gauges. The ones inn the speedo all seemed to be working fine but out of four in the tach only one worked. That's when I noticed that one of the nuts that hold the tach in its housing was missing. Then I noticed the reason the threaded stud for the nut was broke. Now that's not good!
At first I thought I could just swap in the tach from the 1982 Special I have in parts but noticed that the 1982 Special did not have the neutral light in the tach like the 1978. So now what to do? I came up with the idea of fixing the broken stud. Did some digging and managed to find a small bolt with the same thread as the broken off stud would have. Then dug around in my cheep metric tap and die set and was lucky enough to find a tap the same size. I'd have to double check but think it is a 5mm X 0.8 thread.
So today the fun started found a drill bit that would drill a hole close to the right size to tap for the threads. I did a test drill and tap on a piece of scrap steel. Next was a little bit tricky as I had to drill down the center of the mounting stud that the threads had snapped off. Ground the broken area pretty flat and starting with a smaller bit got a hole started as close as I could. Not easy as this tach has a plastic case an using a center punch to mark the starting hole would not have been a good idea!
Once hole was drilled deep enough to get about 4-5 threads in the mount I temporarily chucked the tap in the drill press and turned the chuck by hand while holding the tach with one hand and worked the feed lever with my chin. I'm sure that would have made a good picture. Once I had tap started a couple turns I loosened the chuck with tap still in mount on tach. Then I put tap handle on the tap and used a small pair of needle-nose vice grips to hod the mount stud so as not put any pressure on the plastic tach housing. The I took the tap out and used some cleaning fluid to flush out any taping fluid and chips. I then used a drop of Red Loc-tite on the bolt and screwed it in good and snug. In the morning I will finish up the job by using a Demel with a fine cut off wheel to trim the screw to the same length as the good mount.
Now to get back on subject the 1978 is on a lift in the garage along with a Sportster and the 1982 Heritage Special is parked across the yard in barn with another Sportster. Is that enough Harley contenent?

Since you are in AZ, are you going to make good on your threats to Bob “mailman” and stop by to drink his beer???? Enjoy your trip!!!
