Fredette porting

A local dealer has a 2001 KDX220 in excellant condition.Still has titties on the stock tires.The bike was bought from the same dealer and the buyer had it modified before ever taking it home.He then rode it a few times and then traded it in for a quad.Anyway he had the cylinder ported by Fredeette racing,FMF pipe and silencer,and jets.Everything else is stock.I've had a 220 before and I was happy with the stock engine and never thought about porting.What does it do and will I regret buying a bike that has had this done ? :ugg:

Well not only did I not get any replies on this page but none on the Fredette page either.The dealer that had the bike started it up for me and took it around the lot a few times.I was not able to ride it but it ran and sounded good.The story I got was that some guy wanted to race it in Carlsbad at a Grand Prix but never did.He then gave it to his wife but she didn't like it so it was traded in.Somehow I feel like I'm not getting the whole story but oh well.I bought the bike yesterday and took it to the desert today.It runs great.I don't see much difference between it and my old one.The Mech at the dealer said that it was not radical porting and mainly just cleans it up.He was the one that had the work done by Fredette and then assembled the engine.He was a really nice older guy and he said the bike runs really clean and that I would be happy with it.If any of you SoCal riders are fimiliar with John Burr Cycles that's the place.Tomorrow I will take it out to my favorite place and I will then be able to critique it better.So far I'm real happy with it.I don't know how much it costs to have the Fredette work done but I may have been disapointed if I had paid to have it done.It still seems the best thing to do to a KDX is change the pipe.

The area I went to with my buddy is better for big bore bikes.I like my XR400 for that area.Later the same day I took the bike out to the hills near my house where I go at least once a week and I was able to see the difference right away.Compared to my old 220 this bike is faster in the mid range and on top.It likes to rev just a bit higher but still has great torque.It came with the Gnarly torque pipe and power core II silencer and seems to be jetted almost right on.I'd like to try one up on the pilot but otherwise seems good.My 98 had a Boyesen rad valve so that will be the next thing I get.This bike is a keeper .
