Thanks! They are AC Racing Blacklines for the KLX or Z400. I custom made mounts to put them on the Blaster frame. Including welding the front mounts to the frame. They go for about $300 or so new. I got mine on ebay for $150, they were blems, but they work fine for my application after a little tweaking. I also had to mod my kickstarter, because I moved my peg location down and back 1.5".
WOW those filters are a huge differance, now you got me thinking. LOL Is thaat filter from a car intake??
