I have a KLR650 C5 (2000 reg), and I've spotted a few KLR650 parts over the past few days on www.ebay.co.uk
. One seller with parts is "madbike69". He/she may be able to help you, although I suspect that because it's a front-end problem, you'll see less parts available.
If you're really stuck, I could temporarily cannibalise some bike parts for you, as long as you put me back together as good as before in the next few weeks.
Note, I'm assuming you have the KLR650C (European model) rather than the KLR650A (US model), because the front forks are different (38mm for the A, 41 mm for the C).
If I can otherwise help you from here, drop me a mail.
I hope you get sorted out.
