Getting a new (used) 01 750 Trackbike

[Smokngun]

Hi all, new to the Gixxer forum but I've been on 'zilla for quite a while (My street bike is an RC51). I'm picking up a 2001 GSXR750 thats an ex race bike. I'm buying it from the second owner that has been using it for a trackday bike for the last 3 years. It seems pretty set up; Ohlins rear, some work done to forks, NCR case covers, new chain/sprockets, full exhaust system with Micron can (unknown header), rearsets, clip ons, etc. The problem is, I don't really have any history on the bike with the exception of what you can see on the outside thats been done. Are there any mods I should be looking for that could still be done to this bike? I'm simply going to be using it for trackdays, it was about the same price as just buying bodywork, spare wheels, and sliders for my RC51 so it was a no-brainer to get the bike.

Thanks in advance!
Mike
