Espen, welcome to Tiger land....
Iansoady is on the money with his comments, if you have any problems.
If you're after general maintenance schedule and how to do each check, you can get the genuine Triumph manual, or the Haynes manual for Triumph Triples. That's what I have and it works for me. Take your time, read all the relevant parts and in no time you'll be an expert!
Most of the maintenance is fairly simple and easy to do, even for someone who's never had to do it before.
