Around 300 people did show up during the celebration of 10 and 60 years in business for the two companys supplying the Scandinavian industry with bearings. Nomo is Swedens largest independent importer of bearings and has almost 19 000 different articles in stock.
Now 10 years ago did Rotera start in the same building as the head office of Nomo Kullager servicing customers over the counter. Since the start has Rotera had a quick grooving customer base. The company are very well known for the high grade of knowledge and support regarding bearings, sealings and transmission technology.
“ We are very lucky having these companies close to were we have our race-shop because it gives us the ultimate access to Timken, Torrington, Nachi, and other brands of bearings we needs. Also the support we got in designing our racing components thinking of selection of bearings and seals”, says Charley Karling.

Over 14 000 people did enjoy the 2008 Custom Bike Show in Norrtälje, Sweden. Around 250 bikes did compete in 6 classes for a price table worth almost a 500 000 sek. This show is also where a jury choose a winner that goes direct to the World Championship of Bike Building in Sturgis USA. The number two and three goes to the European Finals in Germany. The winner was Andy, Flying Choppers Finland.

At one of the first times Charley did visit Custom Bike Show was 1974 riding his 1947 74” H-D Flathead Chopper with approx 5-10 hp over the stock 35 hp with it´s relived cylinders and tuned exhaust. At this years show did Charley and the team fire up the new dragbike that got some more power. Three warm-ups with Charley wacking the trottle 30-40% gave a enormous response. Most of the time did the team keep the bike undressed to give time for the visitors to see how the bike is built. Charley, Mats and Carina did answer questions all day long.

May 24 - 26th 2008 Main Event Santa Pod England

For the first time on the track with the new bike.

It has been a long way, from idea, planning, designing, chasing parts and manufacturing to get there, the first time open the trottle at the track. The list of involved people is so long that it needs a separate story to describe how the work has been done and by whom.

Two days before the event was spent in the pits by the team starting and testing systems and set-ups. The team was Jarmo Pulkkinen, Mats Tärnström, Carina and Charley. Hans Björkman, machinist and inventor who has spent days and nights in the Karling workshop together with Mats and Charley, stayed at home following the event. The Super Twin Rider Greger Johansson was also in team for the weekend and will also be so in Finland. Greger is making new engines and will be out later during the summer. Christian and Viktoria now with the little daughter Liv and changes in work situation do not have the time to spend the time that is needed.

We did miss the first qualification session because we did not get the right temperature at the rear cylinder. On the second session we were out. The engine responded very well and the clutch hooked up as it should with only the primary arms in the burn-out. Maybe the rpm:s went up a little bit to high, the wheel speed went up to 380 km/h (230 mph). It´s tricky to know the trottle response before you tried it. With a fuel pressure higher than it ever had been before we got a smaller leak from one hose and have to shut the engine off. We fixed the leak easy but as the rules are we miss that run.

Next day rain and wind and the day after that also rain. Not one single round in the European Championship, cars or bikes, could be completed because of the rain.

So we did not qualify and even if we did not get a run it gave us a lot. Just a burn-out and the data we got from it shows that we are on the right track. We did work in the pit for three days starting tuning testing to get a basic setup and also get all functions to work properly.

Since September last year when we started the bike for the first time we have been doing many changes. Here is a few examples. The main thing is a new designed mounting of the front primary drive pulley to the crankshaft. The McClure Overkill crank is modified to fit the new mounting and the main bearings in the crankcase is moved to give more room for the mounting.

The engine also have got improved lubrication system with some new ports inside the Overkill crankcase. Both the feed and return is changed to get better circulation and less outside hoses. The Autoverdi oil-pump is doing its job and the oil pressure variation is only 5 psi from idle 3000 rpm up to 7000 rpm.

The Clutch Cannon is redesigned for other seals to prevent the air from coming into the oil.

The 44-amp Dual MSD Magneto Ignition have got improvements with waste spark boxes for the 14 plugs we not have on our two cylinder engine. It helps to keep the spark energy up.

These new designed or modified components seems to work very well and we are sure there will be more when we get more runs on the bike. We now look forward to the next event in Finland in July. But before that, coming weekend Custom Bike Show in Norrtälje SWEDEN.
