I’m coming out of hibernation.

I have been playing with circle track cars the last several years. While it scratched the itch that is my need for speed, it’s not quite the same as MX. Racing cars is work but not really exercise.

I am now the proud owner of three ‘87 KX 250s. I bought the other two as parts bikes, but they are too nice not to restore.

I want to build each of them to different specs. I have compiled a number of parts and pieces. Since components can be swapped from one bike to another, I plan to mix and match then ride them back to back to find the recipe I like best.

A month ago I took a road trip vacation on the west coast and dropped by Pro Circuit. Jeff Ward’s Supercross Championship ‘87 SR 250 was on the showroom floor. I took lots of detail pictures and will use them as guidance and inspiration.

I also visited Dave Miller (DMC) while in Anaheim. He is so cool.

Do you happen to have a silencer in less than usable shape for your builds, that you'd be interested in selling?

I thought I had an extra stock silencer, but I haven’t found it yet.

My ’87 silencer looks like it matches my brother’s ’88 except the inlet pipe is longer on the ‘88. I’ll borrow his and see how it lines up.

If an ’88 silencer just needed to be shortened, that would open up some options for used silencers. ’88-‘89 KX silencers share the same FMF part number as ’89-‘94 KDX 200s.

Looks like shortening the inlet pipe on an ’88 KX 250 silencer won’t work. The ’87 KX 250 pipe stinger goes a little past the front of the ’88 can.

I have to replace the broken perforated core of my DMC silencer. If I can find the right matching oval aluminum tubing, I may clone it.

DG has ’87 KX 250 silencers new in stock for $140.

I saw some old style cloth Renthal crossbar pad covers for sale. That got me to thinking I should get one or several to make my ‘87 KX 250s as period correct as possible.

Mine back in the day was white with blue lettering, but what colors were on Jeff Ward’s Supercross Championship bike?

When I saw Jeff’s bike at Pro Circuit, it had a black foam crossbar pad but no cover. I just assumed somebody had pocketed it.

I started looking and have yet to find a picture of Wardy’s ‘87 bike with anything other than a black crossbar pad. Ron Lechein’s and Eddie Warren’s ’87 bikes had crossbar pad covers on them.

There has to be a reason. Did the lettering or contrasting colors distract his vision? Was there a sponsorship conflict?

The 1987 Kawasaki KX250 was on equal footing after adding the cartridge fork kit and DMC pull rods.

I would love to ride both now properly set up and compare them to each other and even to modern bikes. I hope to get that chance at a vintage event with Evo 4 classes.

Phantom what did the pull rods accomplish? Did they raise the rear a bit or lower it?

The pull rods raise the rear 12mm/ 1/2" to help cornering but more important they keep the tire from rubbing the under side of rear fender. I have them on my 87 KX500.

Probably one of the best 250 motors Kawi made in the '80s was that '87 KX250. Barked right off the bottom.

Queen,

The DMC Pull Rods were shorter than stock which raised the rear of the bike and in turn steepened the angle of the forks. This made the bike turn better, but somehow didn't seem to cause more headshake. TUF Racing had a version as well.

This must have also made the linkage more progressive, because I had to drop back to the stock shock spring rate to compensate and rebalance the bike. A similar thing happened when I went to the cartridge fork kit. For perspective, I weighed about 165 lbs at the time.

I spoke to Dave Miller at length a couple years ago. He said Kawasaki improved the stock suspension geometry for the '88 bikes and no longer needed different pull rods.

One of my favorite motors on a 250 two stroke.
