Have been reading up on the bikes, and as far as i can tell it is a rc04, which is from Germany(i live in Denmark) and theres lots of info on German sites.

I have been mending it slightly but i have run into a problem. Suddenly after a week where i didn't start it, it wont fire on the 4th cylinder :( Tried taking the plug out, theres a spark, then tried heating it up with a lighter and putting it back in, the it fired while idle'ing, but stopped when revving, and had trouble idle'ing down, but eventually it idled, without the 4th cylinder. Now the above method doest work, although i only tried once after.

Next things to test is a compression test, but dont have one, so i'll have to go get one.
