Hi there, I had those models and as far as I know there was not a work shop manual only that later 98/99 one. I used the husky 1983 four stroke manual and it was very good. I used later versions of the early husky manual (90/91four strokes) for wiring information, but the 83 manual was my favourite source of information. The 91 berg I beleive was really a shrunk down light weight version of the husky motor and may have been on the husky drawing board for a while before going to cagiva. I know my tool kit off the 1983 husky was ideal for the sem ignition and other work on the motor...in those days you got fly wheel pullers in your tool kit. The read valve, and gear box etc will be all covered in that manual, the berg manual of 98/99 is also helpful, but the husky manuals are more in line with the 91 berg.
At the time the best thing about the owners manual was on the back. Roland-the engineer's- phone number. How times change?
Remember to get a spare SEM ignition re-wound as sometimes it is hard to know the OEM one is playing up....ie sometimes you think the carbi is flaming the bike out, but it is a bad ingition. Your bike is the only real light weight berg....wish I still had my 93 350 that I could lift of the ground. The cost of reliablity is not worth it as I loved those early bergs with pins not rim locks and alloy cam wheel etc etc.
I found a second hand SEM coil and don`t know if it was the same one but it works! Now the engine runs okay!
