Buying a k5

(1/3) > >>

Rotorised:
Hey guys, im about to buy an early 90's model kx500 (with a little luck) and wanted to know if there is anything i should look out for when buying my bike? Also are there any changes to the k5 in the early 90's worth holding out for?

Cheers

You should check out the top exhaust mount, which just about always breaks under the tank.
They just need a bit of 1/2 by 1/8 flat steel welding over it and that seems to sort em.

Remove the flywheel cover and check to see of you can waggle the flywheel, if you can then the crankshaft bearings are knackered (or the flywheels loose).

I think that there's very little difference between the 90 model (like mine is) and the last ones made.

Fork diameter in the 90 model is 41 mm and the later ones get bigger forks and also the flywheel is different from about 92 aparently which can affect it if you want to fit one of the fancy E-line accessories lightling coils thats built into a flywheel weight (the flywheel weight/lighting coil fits the later ones but not the 90 model) but that only affects those who want lights on the bike.

Timbowe:
All fairly much the same apart from as Demo said fork diameter. 43mm didnt happen till the last of them. Check for slogged out footpeg mounts, rear suspension movement, steering head bearings and would be good if it had a late model kickstarter with the meaty bit on the bottom where the steel rod goes through. The often replaced parts are inexpensive tho and with a bit of TLC you'll have a top bike. Good luck and keep us informed. :mrgreen:

Thanks for the info guys, now all that is left is to wait for one to come up in the local auto trader :(  will try and post pics once ive got it, although i doubt it will be the most glamorouse of bikes, due to buget  :wink:

Looks does not matter - power does!

I prefer a mechanically sound, tatty looking bike any day. No one wants to steel your bike if it looks like s**t.
