Hi there, if any of you folks have read my introduction then you will have seen that on Friday I am swapping for an XB12R. Bike is standard apart from a Corbin seat from what I can see, needs a bit of a clean but is in otherwise good condition. Comes with an upright bar conversion and a quill pipe (which based on the reaction to them on this site, will go on E-bay) as extras.
Bike is a 2005, with 10,600 miles and has done very few miles since going through the MOT last. Slightly worryingly, when I test rode the bike it became blatantly obvious that the front disc was utterly bolloxed, with the lever pulsing and the bike being relatively unstable (could feel bars trying to wobble) when the brakes were anchored on. This would lead me to believe that the previous MOT was either not particularly in depth or maybe just carried out by an utter pants-on-head. The present owner maintains that the disc is fine from 'looking at it' which would also lead me to believe he wasn't the most clued about Buells or bikes in general. Fortunately he has only owned it a short while so hopefully damage will be limited

. Other than that, the bike runs beautifully, got torque, active valve is working, new tires, very few marks on the bodywork, all electronics are alive and well... Like I said, just needs a bit of a clean for my standards to be met.
In order to remedy the disc issue, I have already purchased a EBR 6mm disc along with the EBR mounting kit and new pads. Bike also has the stock tensioner, so I have also ordered an FS tensioner to go on her for piece of mind. Got a few crash bungs while I was at it and a couple of spare oil filters to boot, but held off on the oil as I wanted to ask a few questions of the tech head on here first.
If you had just picked up a 10,000 mile Buell with relatively unknown history, then would you flush it through by doing a couple of oil changes with varying grade oils? I was just going to plump for the expensive 20-50 stuff that Trojan Horse recommend but I don't know. I think for piece of mind I'd like to do a couple, one with the treacle that Harley do, then with the performance stuff... Any recommendations?
Also, any areas on the bike I should be looking at given that it is a stock 10,000 mile bike? I know with that stock tensioner the bearings are probably going to be junk every few thousand miles... I've learnt quite a bit off this forum with the search so far but any in depth knowledge will be supremely appreciated.
Oh, and I already have a Stealth pipe coming to replace the stock can. I know they split opinion but to me they look awesome.
