Title: 1986 CR250 Build
Post by: rsmith on June 19, 2017, 08:34:27 PM
A very (very) long time ago I was given an 86 CR250 that needed a crank.

It's under a tarp in the back yard but I just found a nice looking crank for it on eBay so, just maybe this may live again sometime soon.

I'll post it up as I go.

Crank is back from the machinist fresh rod and bearing.

I can't find either of the side covers for it, which is a bummer. Turns out the newer (up to 91) will work but I need to find an earlier style power valve governor.

I am kind of surprised I managed to hang on to as much of the engine as I have. I have moved several times over the years...

A funny thing happened at the vintage races today.

I picked up this mostly complete 86 CR250 and the guy who declined to buy it wants to sell me another mostly complete one too.

I went from one to two and likely a third.

Now the question is how many do I build??

And then there were 3....

The guy who was going to buy the last one sold me the one he was building.

Now I have 3 almost complete 86 CR250s. Now what do I do?

yes i believe Honda nixed the magnesium right side case as well, making them much more reliable.
