Question about Jeff Ward's 91-92 500s

(1/2) > >>

SteelHorse751:
 I have been watching some old motocross videos on youtube and from the looks of it, Jeff Ward's bike "look like" a "normal KX 500.

 I am sure that the suspension has been worked, and I found the thread on Jeff Wards engine, so I know it was 'massaged".

 So I am curious if anyone knows if the frame geometry on his 91-92 500s are different than the Production KX500s.

 In the video from the 1991 500 USGP at Glen Helen, there is a good view of one of the 250/500 Hybrids that some of the guys were running back then.

 Just curious to know how much different the bike that I will be getting is from what he was running back then.

Thanks

My documented jeff ward bike is the same geometry...

suspension was Custom on the inside.
all welds on frame etc were done by hand
added guards
motor stuff
etc..

 Thanks Motorrad!

 So at least with some suspension work I now know that the geometry of the original frame can work for what I want to do with the bike.

 Great news!

Also look into the Procirciut pull rods for the rear end...

  When you say pull rods are you talking bout what some refer to as Dog Bones?

 If so, I read a thread on KXRiders about how shorter dog bones (pull rods?) raise the rear end some and help the K5 act better in the turns.

 I will keep my eye out for them as I also read that used or ebay is where they will have to be found now.

 Thank you
