SX engine - 6 basic mods

[amquadracing]

Kiwi, I still havn't got the DJH tensioner, still stock unit but thinking of doing the oil pump mod, do you think i'd be better adding just one 1MM washer/shim

[sticko2]

1mm washer with stock tensioner, 2mm with manual one.

I have been waiting the washer like 1 month and a half from ktmcyclehutt.com...
Can I use another washer or the ktm washer has something special?

I just used 2 standard washers. Think I have about 2.5mm of peload.

Put a new spring and one washer in while doing my casing build, the oils really motoring in the oil window now, more like a honda!!

Does the Honda clutch plate mod work in the XC engines? My stock ones are slipping a little so Im guessing they are getting gunked up.

[sticko2]

Honda clutch setup is sx only I'm affraid.

[jzexrider]

So are stock ones my only option? Or is there any better aftermarket sets that you know of?

Rocky mountain atv has some aftermarket option,but the oem honda fibers and steels work really well and are proven.Stick with that.

I think he has an xc so the Honda's are out the question. I'm sure there are options from tusk and ebc.

Yeah, I have an XC. Let me explain the problem.

It dosent always do it but its getting worse. When Im stopped on flat ground or a slight incline, as Im letting the clutch out, it seems to slip just a little and then jerk a little and then it grabs and takes off fine from there. And sometimes it will also make this high pitched squeeling noise before it grabs. But I havent noticed anything unusual when Im riding.

Does this sound like the plates are going bad or something else? Thanks for the help.

3/ CLUTCH SPRINGS

add a replacement set of HD clutch springs (for the KTM 450 - 505 SX-F dirtbikes)

Pro-X part number SPRING KIT 17.CS64042

can't find the Pro_X, check with EBC or Barnett they do uprated spring kits also

EBC part no 15-17136

the stock springs are on the whimpy side, I've experienced clutch slip / delay until the clutch bites in, in the higher gears in hi traction situations. With the stock frictions this peels off strands of ultra fine clutch fibre that then builds up around the oil pump intake screen, looks like sodden cotton wool !! all the more reason to ditch the KTM frictions as per 2 above whilst your in there.








Anyone know where I can find these spring kits? I checked both rocky mounton mc and motosport outlet and neither have those part # when I type it in the search.

[harry_ss]

I bought Barnett springs for my 505 from www.powersportswarehouse.com
Barnett Part # 501-63-06014
Distributor Part # 2012-314

Regards!
