Oh christ, he asked the oil question.... Welcome Chris Oil is a much discussed topic - some (the misguided fools )will say you must buy bike specific oil such as Motul 7100 or similar, while others will say that if Mr Yamaha states CF or SL spec (which he does, for an FZS600) then any that meets that spec is champion. I'll leave you to work out which camp I fall into .Filter wise, I've always used generic from my local bike shop, never had any bother.
I'm staying out of this ... I refer m'learned friends to previous discussions.http://foc-u.co.uk/index.php/topic,666.0.html
Great. In regards to champion oil can anyone recommend a good supplier. Also would you recommend putting in a K&N air filter?
