Have you upgraded the suspension?, I noticed a big difference on the stability and hanlding of the front end when I fitted some ohlins springs, changed fork oil and seals aswell. sae10w motul fork oil. Its quite an easy job to do as long as you've got the tools. Took about 4-5 hours for me but can be done a lot quicker if you have a bit of experience. The springs were �100 ish from ebay.
