125-200cc Well slap my A$$ and call me Sally! (2012 CR 125 ignition)

Sally!

A Walt Modified KTM 200SX (2003-4) FMF Fatty.

My guess is you wouldn't like it. My 2012 WR150 has it and it works great for what I am doing but the flywheel has some weight and takes a tiny bit of spinup to get things rolling and you MX'ers might not like that. Just remember that setting up the little bikes properly involves manipulating minutiae!

Ah. That's the one he recomended when we talked. Do you know what the modifications are? Please be sure to post your ride impressions after the race.

The 200 sx fatty pipe doesn't tuck up out of the way the best. It does have the best spread of power of the 7 pipes that I have tried. This isn't conclusive at all and I expect more options to be tried. Conversion of the pipe is simply a matter of changing the spigot that fits into the cylinder(angle too), new stinger section, and moving the mounting brackets. Pretty easy really.
new versus modded pipe.

what is #2-3 on your list if the SX pipe is #1

I made a hydraulic clutch setup for my 125s useing AJP master cylinder and a not to sure what the slaves are from and you can pull these in with total ease with just your little finger, and as a added bonus the clutch arm on the cases has a couple of millimetres more travel so no drag ever even when cold !
Absolutly a brilliant fantastic wonderfull fade free super dooper total must for any bike and really makes the light standard clutch pull seem STONE AGE

Thanks for the info Walt. Looks like my buddy with a welder will be getting some work.

The clutch pull on my 125 is quite a bit lighter than that of my KTM 250 or my buddie's TXC 250 with magura hydraulic units. I also don't have to worry about the slave or master cylinder failing like it did on my 250. YMMV.
