The day before Christmas eve, I finally had time (took a day off) to cross "Øresundsbroen" - which connects Denmark to Sweden:

It's a combined tunnel and bridge, with an overall lenght of approx. 9,9 miles. It was early morning when I crossed. The sun was slowly rising from the heavy rain clouds in the horizon.
I was going to pick up my Kawa engine -/gearbox which for the last couple of months have been at the Swedish two-stroke wizard Ebbe Parnestål.
Eptune, Ebbe's shop, is lovated in the outskirts of Malmø. He deals almost exclusively with two-strokes.
Looking forward to see the engine again and to some holidays, my spirit was sky-high when I crossed the brigde
You can see some of Ebbe's previous work here:
http://www.ebos.se/eptune-triples.phpPretty amazing stuff I think !
This is how it looked when I picked it up:
soo nice - I think it deserves a couple more pics:
There is always a number of triple engines on Ebbe's desk, and very recently he refurbished a H1R engine from a barn find. Bike now with a Swedish collector undergoing restoration.
Here is the list of the major tasks done:
- dismantling, cleaning and measurement of all tolerances.
- Cylinder rebore and porting.
- Mounting af 3 new Wiseco 61 mm pistons.
- Work on crankshaft including new seals.
- 3 new small end needle bearings.
- 6 new, low-friction bearings for crankshaft.
- 3 new conrods.
- Gearbox shimmed.
- All bearings in gearbox changed to new ones (needles bearing and ball-)
- Worn shifting forks had applied metal, followed by grinding.
- "Ball polishing" of crankcases, cylinders and heads (see note below)
- New rivets in clutch housing .
- New stronger springs for clutch.
- New front sprocket etc.
- new clutsh releaser all-metal.
- Drainplug magnetized.
- Engine and gearbox assembled.
So it was almost a matter of plug-n-play. Engine was ready to mount in frame
Actually I would have enjoyed to assemble the parts myself, but after all, Ebbe can do that much faster and better than I would have been able to, considering his huge experience.
Note: Not sure if "ball polishing" makes any sense. I have in fact made a 1-to-1 translation of the swedish term
When reading about the process from the swedish company, it's kinda like a big tub clad with rubber on the inside. In the tub are 1.2 tons of small stainless steel balls, 1-5 mm in diameter plus some anti-friction gel. The parts to be polished are sunk into this tub, and it vibrates with a frequence which also makes the parts rotate in the tub.
Any which way, the result is excellent, very gentle to the surfaces, and the resultant look, is neither too shiny or too dull. From what I have read on various MC sites, the finish is very long lasting. Only drawback is that you must clean the parts metodiously afterwards. But I guess this goes for vapour balsting as well.
