Not sure if this is the best spot for this query...? Asking for my brother who has recently bought a Z300, and is thinking (already!) he would like a little more. Before going out and looking for alternatives, he has had a chat to his local dealer, who has suggested that maybe, instead of another purchase, to do a bit of an update on the Z300. His suggestions are: 1/ Fit a Yoshumira Slip on at about $500-00 2/ A Bazzaz after market ignition at about $500.00 Reckons that this will give him 4-6 extra HP, or maybe even up to 10... (Standard about 35.) Has anyone done this, or know if this sounds reasonable, and what sort of a 'noticeable' difference will this give to the performance of the bike?? All comments appreciated.
