I'm the same way. There are a lot of things that I'd rather do myself simply because part of the fun of owing a bike is working on it. That is just an opinion of course. What you want is either the
Triumph Sprint ST and Sprint RS Service Manual part # 3850760. (This is for 99-00-01 Sprints. I found mine on Ebay. The 2002-3-4 manual has another part #)

Or this:
==> Haynes Service & Repair Manual <==

Also for for 99-00-01 Sprints (note the cover). I don't think that there is a Haynes for the 2002-3-4s. BTW that is the best price I could find on that. $26 including shipping. I've had good luck with Haynes Manuals. I only bought the factory manual because I just happen to see it on EBay at a reasonable price. Good luck with all that.
