Hey all, First time poster here and wondering if I could get some advice on a 2001 CBR900RR i just checked out tonight.
It looks all stock (except some after market mirrors) and it has done approx 24,xxx km's.
We started it up from a cold start, it started straight away but the idle seemed a little erratic. As it warmed up to temp, it lowered down but the needle did move up and down a little. Not sure if its just ment to be purring along constantly at the same rpm, or if its normal for this bike to jump up and down approx 100/200rpm?
Another thing i noticed is the oil, When i took the oil filler cap off and had a look, there was a whiteish residue on the cap. Upon further inspection of the oil viewer/inspection glass, the oil looked kind of yellowish. I would like to think with all the previous cars/bikes i have owned, old oil should be black. And black only. Unless obviously it is clean oil, but i was a little skeptical. The owner has only had the bike for 7-8 month's and has not serviced it in this time frame, but has put on less then 1000 km's since ownership.
The owner had said while riding the bike had coolant pissing out everywhere from the overflow (sounds like it had over heated?), later to realise the dealer he bought it off filled the radiator with just water, not coolant. Not sure if this means the motor has been over heated or not as i am unfamiliar with these bikes.
When it was running, i noticed some water/vapor/condensation spitting out of a join of the pipe, looked like there were some holes in the exhaust. Not sure if this is normal for a stock pipe? The swing arm started to get spitted on with ugly looking water.
All in all, cosmetic wise it looked fine, nothing too much to worry about, slight crack which looked like a fairing had been over tightened.
If somebody could clarify if I should take a punt at this bike given the description of the oil, would be much appreciated.
I am mechanically minded, and willing to give anything a go in terms of rebuilding, I just have to take any additional parts required into account.
Hopefully someone can help me out and maybe i can own one of these amazing machines
Sorry for the long post!
