I used the stock 500 clutch cable. I bent the metal tube so it will route in front of the radiator just like the 250. That eliminates the sharp bend at the top of the radiator when routing it like a 500. Seems to ease the pull somewhat. I use a Moose clutch perch/lever with 2 holes for the cable and a bearing in the pivot. The pull is as easy as a 250. Ive tried juice clutches before on a YZ426 and a CR250 with poor results. It gave them a on/off feeling with no "feel" or modulation. Plus both started leaking at the slave cylinder during a race and left me with no clutch. I went back to the cable after that.

I was able to get the cable in the perch, but it is too tight for serious riding.  It does have a nice light feel though.  I think I'll order a 500 cable and see if that helps.  I don't think the cable the guy gave me with the motor was for the 500.

umberto:
Rocky Mountain does not have a clutch cable for the 88 K5.  A 90 cable should work, correct?

zz3gmc:
Not sure, the part #s are different. If the mounting point on the case is the same I dont see why a 89-04 cable wouldnt work. Can you post a close up pic of the left side of the engine?

motopunk:
the cable works .. i have one on my 88 motor ..  kx250 and 500 could be assembled with the same cables 88-2004 

it could also fitted to 85-87 motors, but thatīs not the point here ...  :wink:
