    Well it seems like im sucked into the bikes produced during the year of 1984 because I started another project bike which is a little brother to the 84 xr350 that My father and i finished recently.

    But i picked up an awesome deal, found a guy up in Denver selling a 1984 cr125. The bike was apparently rebuilt about a year and a half ago, but it seems like everything was not gone through. The bike was not running when we picked it up but seemed to be in pretty good condition. We only paid $250 for the whole bike which is amazing considering that it only needed some time to get it running again.

    will post pics later today, but wanted to get the post for rebuild started. Anyone have any experience with these older 2 stroke bikes?

    well if you go buy a bike and it doesnt run i would definitely ask the seller if you can pull the cylinder to see if there is any damage to the crank or the piston cause it can get pretty pricey to fix that stuff if your trying to keep your build cheap, and parts can sometimes be hard to find. so bring some tools but the two strokes for most brands in this year range are extremely easy to get to and remove.

    thanks for the advice. finding the right bike on the cheap is proving to be a challenge so far. i guess the early 80's bikes are old enough to be considered 'vintage' now because it seems like they go for as much as a mid to late 90's bike if they run. but the majority of them either don't run, are missing parts, plastic is broken or badly sun-faded, etc, etc.

    i'm scouring craigslist like a mad man lately though lol :D

    If you are going to do it you have to do the crank and seals, the seals will leak if not done and mess up the whole bottom end. The other issue with the Hondas is the waterpump cavity because the cases are magnesium they seem to "rot" from the antifreeze and just start to crumble.

    I just re did this 89,
