Re: 81 SS fresh engine

Changed oil after Kansas and headed for northern Wisconsin and cooler temps for the 4th of July weekend. Really nice ride around the Turtle Flambeau Flowage. Back in Davenport Iowa Sunday night after 995 miles. It's been 3485 miles since May 19th, I'm pretty sure everything done to the engine is goi...

Re: 81 SS fresh engine

Rode to Kansas last weekend for the AHRMA races at Heartland Motorsports Park in Topeka. Temps in the 90's, don't know how the racers put leathers on and go race. Parked by a pair of Panigale V4's. https://i.imgur.com/bat2ZYf.jpg Stayed in Gardner Kansas, nice town. Just outside of town is where you...

Re: Better Oil Flow to the Sump, And filter ALL of the oil.

After 1380 miles it was time for an oil change but first I wanted to move the oil restrictors in the cam supports to the cases to take pressure off the o-rings in the cylinder to head joint. I pushed some thick grease into the passages and tapped them to 5/16-18 maybe 3/8 deep. Was no need to drill ...

Re: Better Oil Flow to the Sump, And filter ALL of the oil.

Update after 856 miles. After a long high speed interstate run I noticed oil drops on the case behind the rear head. It's coming from the head to cylinder o-ring. I think when the oil is cold there is more pressure than the o-ring was intended to hold because of the restrictor in the cam support sho...

Re: Better Oil Flow to the Sump

The old pump outlet is plugged with a short setscrew. https://i.imgur.com/7xCirch.jpg The restrictor Ducati presses into the crankshaft was drilled out - it looked like a spring pin. Brass setscrews with a 1.5 mm hole drilled thru were used as restrictors in the cam supports. The heads are still com...

Re: Better Oil Flow to the Sump

I chose a WIX 57035 - it's short, used on a lot of small engines and available at auto parts places.

Re: Better Oil Flow to the Sump

So, at this point I have an oil pump shooting oil straight up the center of the filter housing, and that won't work with a spin on oil filter. The oil goes up and in around the outer part of the filter body, through the filter element and down and out the center. Luckily there is quite a bit of room...

Re: Better Oil Flow to the Sump

Yes, the body is 6061 aluminum, the gear shafts are pretty hard but turn nicely using ceramic inserts. There are pumps available to buy, but it was midwinter and I had a machine available. I think I bought 4 pumps from various Ducati's and they were all very similar. I did find the drive gear arrang...

Re: Better Oil Flow to the Sump

This engine has close to 300 miles on it in the last couple weeks and all good so far. There were a few more mods done to the oiling system than just drain holes in the cases. When I took the original oil pump apart it looked as though it had been pumping gravel. Good condition pumps or pump gear sh...

Re: New ignition system: need advice!

The wheel guide sleeve is a bushing with a key way that slides on the crankshaft. The trigger wheel slides onto it and the setscrews are tightened after timing it. In the future if you have to remove it, you just slide it off the crankshaft as one piece without disturbing your timing. I find the key...

Re: New ignition system: need advice!

When you time the Sachse ignition you will need to know when the front piston is exactly at the top of it's stroke. I used a 1 inch travel dial indicator on a magnetic base with a 2 inch extension to reach down the spark plug hole. They supply an led indicator light that you temporarily hook up and ...

Re: 81 SS fresh engine

After this busy weekend is over I'll show what was done with the oil pump and filter in the engine and transmission section. I can just add to my
post about better oil flow to the sump.

81 SS fresh engine

Two rides and 60 miles on a rebuilt engine that came from a crashed Darmah. Engine oil system is modified so all oil is filtered before going to the crankshaft and heads. The primary gears and cover are Brook Henry VeeTwo items but the dry clutch is from a Ducati Monster adapted to fit. Really makes...
