I include some pictures from my Leicester days with Norwegian Reidar Eide and Ila Teroma plus some pictures of some of my veteran bikes I have restored, I think I have around 11 different bikes now, and some pictures of an off road bike I build with a GM engine, running on petrol and built into a Yamaha XT 600 frame with a Norton 4 speed gear box and a NEB belt drive clutch and some Enduro guards and lights.

Ernst's upright GM off roader
 

Strange to see a GM engine with a gearbox (from a Norton) and the bike with brakes etc.  I have asked Ernst for his bikes' 0-60 time, top speed etc
 

Ernst says: The top speed I don't know, at the moment the gear ratio on the old Norton gear box is quit low but it runs very smooth at around 80-90 km/h and it does that at around 1/4 to 1/2 throttle, her the engine runs nice without vibrations and can last very long without over heating, I have lowered the compression ratio to around 1:10,7 and ignition advancing 12 degree and runs it on plain petrol, it is very hard to find a filling station that does methanol, :-) , I have made a oil tank with a capacity of around 2 litre, so the total oil circulation amount is 2 1/2 litre, this also helps cooling the engine, at the moment I only have a battery for the light, but I have made a new side cover with a ignition/charging system from a small motorbike, so the bike can charge the battery it self, but I have not found time to fit it yet.

It is a very nice bike to ride, its not for high speed racing with the big handle bar, but on a sunny day I love to go cruising in a nice up right position and the sound is very nice, almost like a speedway bike, just cut the top level away.

The engine is made out of I guess 5 scrapped speedway engines, for many years I repaired and tuned a lot of engines for myself and other Danish riders and kept all the old bits and pieces, and then one day I decided to build myself a off road bike of the left overs, even the crankcase is made out of two different halves, all together the bike is made on a very low budget, I have found and swapped most of the parts, only the wheels is brand new from Talon, but my daughter who has a motorbike workshop and is Talon dealer, made me the wheels at cost price, I believe that the bike cost me below £1250 and that makes it extra fun.

Well I think that is almost the story about the GM off roader. Next week end I have been invited to a show in Denmark, that happens in between and it is nice to get a opportunity to show the bike and talk to interested people.

 Best regards from Ernst in Denmark
