Your stock needles are not adjustable, that is the biggest thing. I bought the HRC kit and I used very little of it. All of the main jets are too big for oil pump running NSR's. The only thing I used were the B needles, needle holders, & needle jets. I had to order main jets starting at 150 mains and all around that size from there till I got think good. I'm running Tyga GP pipes with Tyga mod. air box lid, live in Sandown NH. You can get just parts from this guy in US. http://www.redline-ci.com/ He's nice to deal with and he was living in Durham NH untill this summer and moved back to Cali. But still quick delivery from across country. Read the jetting section in the tunning section of this site, it help alot !
