The cylinder and head are on the way and should be to me by the 7th. I talked a good bit with Jeff at PR2 and I’m really excited to get this going. Jeff said this will be a top end monster, so I’m already looking into a fly wheel weight. We discussed ... more »

I did talk to them but they are only mapped for euro fuels. Apparently no one in the states can map them, but they did say they are working on getting a distributor that can

I’ll keep a lookout for you. Would an 04 fit?

I’ve heard about the 3rd gen vibrations so I was excited to get the rg3 because of that, but I’m also coming off a 14 250sx that vibrated like nothing else lol. I found the clamps on eBay

I’m going to ask him about the squish. He recommended 102ish octane, so I’m guessing I could get away with straight 110 and the thinner base gasket. PR2 is known for making very good power so I’m going with his recommendations to start with. If I feel ... more »

Another friend on here was nice enough to design a coil relocation bracket (like on black diamonds build), and another poster on here is willing to do the machining for me. I may not do the relocation just yet, and will wait until the end of summer.

A friend of mine that posts here sent me some suspension for me to try out and see how I like the settings. The shock looks a little different than my shock, so I may end up running the valving stacks in my stock shock, and will refresh the forks. I

I really wanted some red PC triple clamps, but settled for some RG3 clamps. They are in good condition, but it almost looks like simple green or a degreaser was left on it for too long on a couple spots

On with the parts. I was able to get a “oem” pipe, but it turned out to be a PC works with no tag, the old box it came in was marked “one off works” on the side. It was spray painted silver, but to my surprise it appeared to be in new condition. I spent

I picked this bike up from the second owner (15 years old?) and it was obviously low hours. I haven’t quite finished my PC kx250 yet, but I decided to start on this. This will be my race/play bike, so I’m not going to crazy with parts on it just yet.

I haven’t heard anything, but I do plan on doing a build thread. So far I picked up some rg3 clamps and plan on getting a few more goodies. Jeff said 5 weeks so it should be done in 3 weeks hopefully.

If you want a tuner that’s possible to get ahold of and communicates very well, definitely call Tom Morgan. My cylinder is currently with a different tuner and I’m already thinking I should have gone with someone else. I have a feeling I’ll just get ... more »
