Howya all, I have aquired a yam but not sure what the model is as its not on the log book. Is there anyway i can find out from the frame number. 2KR are first on the frame then a few other numbers. Its 1988 4cyl 4stroke 250cc Genesis. I need to get a few bits but not sure of the correct model. I was told it was a YZF but looking at the pictures it dosn't look like one. Any help would be greatly accepted and read over a pint of the black stuff.
