125-200cc I Rode The Prototype Wr200 And It Is Amazing...

Lucky dog! Which pipe did he mod?

Hopefully can get mine running in next few days. All back together but silencer (leo vince) isn't fitting on modified Sx 200 pipe. Have no idea why that is beyond fit must be lots tighter than FMF silencer.

Mine was tight too,I used a dremel with a barrel sander - 40grit , just ran it around the inside a little , slips right on

FMF Fatty, 2004 KTM 200SX. Can't wait to try it at the Nat'l this weekend.

Thanks. I'm waiting on my 165 now. I look forward to your report. Good luck this weekend.

I rode again today.... About 6-8" of snow on the trails and temps in mid 30's F. Traction was minimal, even with short studs, should have had the Trellies today. Bike ran very well and continues to impress with torque. I was able to shift up and lug the bike to keep it from spinning up and losing traction. It had been logged where I was riding, so you had to be on your toes for square edged ruts hidden under the snow. I spoke to Lindsay Pirie at P3 and I'll have Walt's 200 SX Fatty pipe in a week or so to try. Turned my AS in a half turn to 1.0 and bike starts, idles and comes off idle better at temps just below and above freezing. Bike "flat rips" as Kelly says.

Norman, What did you speak to Lindsay Pirie about ?

Lindsay's a personal friend. Walt has sent the 200 pipe to P3, so they can do a pipe guard. E-Line/Moose has discontinued the 200SX Fatty one. Walt wants me to try the pipe after P3 is done with mold and guard, so they are shipping pipe and guard to me. I was just checking the status.

told ya' !!

my leo vince figt my stock pipe but not the fmf fatty (husky 125 one)

Let me know. I would like one for my bike too.

Who is Lindsay Pirie?

Didn't he play "GOOBER" on the Andy Griffith Show ?

How much more gas does the 144/165 use compared to the 125?

Having completed the mod needed to attach my Leo Vince to the SX 200 pipe Walt adapted for me will just say one word to describe the motor, AWESOME! The 165 is very impressive! The RB Design Carb mods made jetting a snap and the combination of the 165 kit, pipe, and carb most certainly work and work quite well. Only one complaint......the kickstarter!!

How did you mod the pipe junction? I have to say that I go back and forth about the kickstarter... longer would be nice, but harder to get on at the top of the stroke.

For whatever odd reason my Leo Vince and the mod SX pipe Walt did had same ID and OD. Ended up cutting up an old Acerbis Silencer and salavaging the flared connector and then cutting and welded it back onto the SX Pipe.

My size 13s have trouble on that small starter LOL!

cedarchopper what carb did you have RB mod? I'm waiting on my 165 kit now but can you describe how the 165 motor pulls/feels? Thanks.

He recut my slide, bored and modied my carb including his divider. I then installed RM needle and jet and beyond adjusting air screw/idle was nearly spot on.

I didn't get a chance to ride as much I'd have liked to because my suspension was bascially stuck on for quick demo down street a few times. I was impressed with off idle and midrange. The top end is there and cannot wait to get gearing right and get a real woods test on it because have very good feeling that this is going to be all one could want in a small bore!
