Cyliner Boring....

Here is one of the Spacke cylinders being bored to size....  This machine is top of the line computor controlled...  It's also scoring the cylinder walls to hold oil on them....

I couldn't upload the video, so here is the link.... just tilt you head to the right or flip your screen... LOL

Spacke Cyliner honing...

Take apart- Part 2

Once we got the flys out, I took a quick pic  so I could highlight the 'master ans slave' setup of Spacke.

We'll look into new valves as the original ones had a little wear on the stem.  The wildest aspect of the Spacke motor is it's lifter cage setup. This design has all the lifters operating on a horizontal shaft off of the flys. The compression release is also part of the setup... Here is the cage:

 The horizontal shaft looks like this:

We tried to start matching a good size pushrod for the trip, just to be sure...

The cases themselves will need a little welding. we found this issue on the inside front cover along with a few stress cracks here and there...

Just to give you an idea of what the compression release setup looks like, here is a quick shot of the OEM.

Since we had a score running in one of the cylinders, we'll have to have it bored out, match a new piston head with wrist pin.     Also on the agenda will be welding the case issues...

Well...here we go !

Hey I know it's been a while... but we had to take care of some business before I got into the Spacke motor... First, I had to realise that I was getting the run around with my 'motor guy.'  Sadly, due to the unprofessional way I was being treated, and the list of excuses  I was getting  everytime I inquired about getting my backup motor (1915 Harley) for the Cannonball back....I had to drop "JIM" from going over my Spacke motor.   I could elaborate a little more,  but lets move on... 
I was fortunate enough to run into Sean Brayton, a fellow Cannonballer, at Rhinebeck.  After  speaking with Sean I soon realised that he was a "No B.S." professional who could get the job done. Not only was he more than happy to go over the Spacke, he asked " So when you want to get started?"   We both knew the answer was ....uh, yesterday..."

So off to Rhode Island I went !   Traffic wasn't bad, but the offseason fog was...

Seans "Customer Service Rep met me at the front door...
Knowing that a cayote likes red meat, I threw him a pic of "JIM."
Seans shop is a 'retro' style first class automotive restoration business.  His forte is high end early autos and has a following that includes Jay Leno himself...

We jumped into the top end to see what we were getting into....  The Spacke will need new pistons... This will turn out to be a one week job...    Unlike a Harley motor whose cams run right off the shaft... the Spacke motor runs a horizontal cam shaft operating the lifters from a cage thats located inside the front cover Notice I said 'cover' because unlike most motorcycle motors, the cases do not split. 

A quick phone call to fellow Cannonballer and Spacke motor runner Matt Olson was needed to get the "take apart" flywheels out of the case...  Yup, 'Take apart'    Try goin 3200 miles knowing that your flys are not balenced together and torqued out of the cases....

They just don't pop out either...

... Let's not forget thay have what looks like small flys attached to each side

After 1/2 hour, victory was ours....

.....more to follow.....
