KDX200 RB head mod

RB designs has a cylinder head mod that they do. Does anyone know if this is worth it? It's only like $40, plus shipping, so I was wondering if anyone has tried it and what it does to the power. Will I need to rejet? Probably not, I assume. This is the exact thing that the site says about the mod, so tell me what you guys think!:

This modification is a great enhancer to all of your performance up grades and will give you an additional boost.

I mill the surface and re-cut the squish band. This gives the 200"s more bottom end torque and a snappier rev.

are you a member at kdxrider.net, if not become a member and say ryan refered me to this site. Many people have done this mod.

the carb mod is a better mod. i had the head mod done at the same time. the carb mod is the best thing i did to my kdx200 and like the guy above said you can find alot of good info at kdxrider.net

I Don't know how a stock KDX runs but a fully modified KDX I can speak for.as far as RB or Fredette doing the work I would have RB doing the work if I did it again, lots more user support. Fredettes work is good just not as detailed and more like a this has worked for me and it will work for you deal, which is Great by me his record speaks for it self,and My engine speaks like a 250 with a much better powerband .mods done: head milled,cylinder ported ,cylinder plated, carb bored from 33 to 36mm there is a lot of good info at kdxrider.net

do your searching first cause over there your question has been asked a few times.

are you a member at kdxrider.net, if not become a member and say ryan refered me to this site. Many people have done this mod.

Who should I tell Ryan referred me to? RB designs or KDXRider.net? Any why say that?

      Hi all,
      I have a 2004 Kawasaki kx250 that died suddenly on me the other day. all i can get it to do is backfire every once in awhile. Tested the resistance and everything of the magneto and stator with a multi-meter and all is good.  Coil is new oem Kawasaki the reeds are brand new vforce and the top end and carb have been completely rebuilt.  key on crank is intact and all the timing marks are lined up. I hooked a timing light to it and spun the motor over really fast and found that it is sparking way to late.  The service manual says that it is supposed to fire 14 degrees before TDC but it is sparking way after TDC.  Im thinking its a fried CDI box since its the only thing i wasnt able to check.  Any help would be appreciated

      Hi all,
      I have a 2004 kx 250 2 stroke and it wont start.  it only backfires.  I was out riding it one day and came up to a stop so the bike was just idling and it started to try and die so i revved it up a few times then let it die and now it wont start back up.  It only pops or backfires when you kick it.  Its getting good spark and i just put a brand new plug and coil in it. I took the reeds apart and they look like they're brand new.  It was running great before so i dont know what happened.  Im thinking it could be a fuel problem even tho the plug is a little wet if you take it out after a bunch of kicking.  Any help would be greatly appreciated

      Alright, found three bikes all located where i live in Texas. I know they're all very different, but if you could tell me what you think each bike is worth, and which one would be the best deal. Thanks.
      Notes: Both 2 strokes have new top ends. I think the front brake lever is broken on the kawasaki.
      KX250 2002 $800-$1000?

      YZ125 2000 $1250

      KTM 400SX 2002 $1200

      So I'm at a bit of a cross roads, I currently own a 06 rm250 and I love it. I also have a 02 kx250 which I'm selling with intent to buy a newer two stroke. I can't afford a newer ktm and the older ones aren't that great and kawasaki never impressed me. so I'm stuck between 06 yz250 and 05 cr250. I've heard the yz and rm after 06 are almost the same bike just the Suzuki handles better and the Yamaha has better suspension. So I'm not sure if I wanna buy carbon copy of my bike with slight differences. That's why I'm interested in a cr250 I heard the 02+ models RC valves are shit garbage but was mostly fixed in the 05-07 models. I ride at a track and at some bogs down the road from me. So from people who have owned both, what would you recommend. I know the cr is known for a hard hitting power band which I enjoy since im an aggressive rider. Should i just see which deal comes my way first.
