So a week or so ago, I got cocky when servicing my CBF250. I managed to install the oil filter backwards, of course blocking the oil flow. Long story short(ish), I rode 36km like that, then diagnosed the problem and flipped the filter around, but the damage had been done. Took it to a bloke suggested by a mate, who diagnosed a stuffed big end bearing. Due to it being 60,000km in, I'm told by multiple sources that it will need a full rebuild, quoted around the $1800 mark. The bike's worth MAYBE $1500 running right. I've bought a new bike, but I'd like to figure out what sort of lifespan this one will have. I no longer care if I bin it, so my thoughts are to ride the arse off it on the 1000km old Pirelli Sport Demons that are on it, until it explodes. How much fun am I likely to get out of it, considering that it sounds like a tractor after about 200km as is?
