Hey! I just got a Yoshimura slip-on for my 2008 Ninja 250R. Supposedly if I install the Dynojet Jet Kit I get a wider RPM spectrum as well as some other perks. Has anyone installed this on their bike? Can anyone give me any info on this? I would like to purchase this. On the Dynojet website it runs for like $85 (obviously US) so for like $100 CAN it sounds like a good idea. PM me with info please!
