April 1, 200818 yr hi replaced the plug on my 315r at the weekend and noticed it was coverd in black soot. the bike is also drinking petrol and and genraly not running well. could this be a problem with the carb settings? max
April 1, 200818 yr its running rich, is it running bad all through the rev range or only at certain revs? will be the carb setup, might just be the pilot screw but may need to lower the needle or get smaller jets is the bike standard or has it had a straight through pipe on and then the standard one back on? if so the jets will be too big, either new jets or slap the straight through pipe back on GL1
April 2, 200818 yr Author i am running a wez straight through pipe at the moment and i havent alterd the jetting. the bike is ok at high revs but at low revs it is a bit crappy
April 2, 200818 yr what year model is it? Is this something that just started or has it been doing it since you got it? Edited April 2, 200818 yr by Neil King
