Few various manual's for the storm for download if you scour the net, and ebay will show up a few different ones,
I have a Corporate Workshop Service Manual used by a dealers (has info and scribblings written / stuck in by the mechanics too) also have a Haynes one somewhere, bit pants this compared to the workshop manual, there is also a different American one on the market too with a black front with images of gears on it, this you can buy and is usually the one offered for download
I have been meaning to scan in the Workshop manual and upload it but its a time consuming task, might set to it when i'm bored and fat after x-mas
