Top End 1987 KDX 200

gopack4749 · 05-18-2012, 05:44 AM

I bought a 1987 KDX 200 to ride perhaps 3 to 4 times a year with some of my friends. That may not seem like much, but I work 6 days a week and have two kids under 6. So, I am trying to do this on a budget, but have something reliable too. I have no idea on the history of the bike so I figure it is top end time.

Start of disassembly:

More:

Cylinder looks pretty rough, but feels smooth. My fingernail does not catch on anything. Might still need a replate though.

Head:

Piston:

I am pretty certain this thing has not been opened up at all. I am taking the piston, head and cylinder to the local mc repair guy today to have him measure it for me. I will see about plating and getting a piston/rings etc. When I get it back together I will post it all up.

it dont look too bad..could probably hone it and go like .25 over whatever the current bore is and it would probably be fine.

also looks like it may have been running with a blown head gasket...maybe

I have been eyeing some of those early aircooled KDX's...looks like a good trail bike

JeffS77-I have seen your KLX in the 'Dirt Bike History 101' thread. I really like it. You need to post some more pics of it and tell some more about it. I am sure more people than me would like to know about it.
