I think that if you go to KL650.net and ask a few questions you will get all the answers you need .
But a good idea would be to get a list of the tools in the bike's supplied kit and then replace them with higher quality tools .
Also check out some of the blogs on this site by KLR riders and glean information about additional tools you might need.
Mollydog [Patrick] has a good generic toolkit photo that he has posted here - that would give you some idea of what you need .
One tip from me - buy your tools in the USA they will be cheaper and of better quality .
All the Best for a Happy New Year !
