CBR250 mufflers dont fit straight on.
I picked up my new 300 on Friday and after a long 500km run home to evaluate and run in the engine a bit I was ready to slip on the Delkevic carbon muffler I had on my CBR250. (despite the press blurb the new muffler still sounds like a cross between a leaf blower and a farm quad bike)
But alas they have lengthened the header pipe by about 100mm so its not a straight forward fitting job.
Unless you can find a shorter linking pipe with the right angles (unlikely) the easiest way around it is to cut the pipe shorter using a cutting disc in an angle grinder. Sounds like a harsh thing to do to a new bike but it worked and you can do it with the header pipe on the bike (make sure you angle the sparks in the direction of the floor) as this holds the pipe firm for you while you cut it. Remove the right hand lower belly fairing first tho.
I love the extra passing power of the 300 but it's not as smooth as my 250 engine was. Once I get to 6000rpm an annoying vibration sets in through the pegs, seat and bars to a lesser extent. Unless I just got a badly balanced motor perhaps. Would be keen to hear other peoples thoughts who have owned both engine sizes.
