Hey Xea,
Must be good working at Jp, first steve has holidays, then you have free time .......not bad !!!
It's a hard life...but you can't weaken ! haha.............
seriously though, I think from memory over the years the most talked about topics (apart from opinions on oil etc ) would be lean & rich tuning, whether or not to remap/ rejet if pipes are changed, vibrations, electrical gremlins, & starter hassels. Pretty hard to work out articles relating to these topic but, because they are so broard in their applications.
Maybe the way to go would be to presume the reader is a complte novice on repairs & run some articles on things as basic as servicing your bike with attention to the obvious things that the book presumes you know ( such as drain plug locations, tapered plugs not to overtighten etc.
Maybe an article on little time & effort saving tips & things to look out for ????
