CR Fork Oil

Today's update is a little slim, things have slowed a bit as I wait for items on ebay to sell so I have more project money. Actually I have paid for my project bike as of this week and I have some reserves in the account however I also have some very large (large as in expensive, tires, sprockets and chains, Piston kit) items to purchase so I have to save up a few more dollars. Much of the cash is going toward the KX project until that one is finished. Its getting close. www.kx125project.blogspot.com . Now on to the CR.

Here is the Oil that I took out of the forks, its a bit grey and murky. The strange thing was when I was draining the oil it ran clean toward the end of draining and looked pretty good. My conclusion is that it has sat for so long that the contaminates settled to the bottom.

After I drained the forks I let them sit for a couple days then took the plugs out and drained them one more time to see if any more had run to the bottom. Then I put several ounces of solvent in and shook that around and pumped them up and down and drained that. It came out pretty dirty and gritty so I did that until the solvent was not so dirty after which I let them sit opened up at the top and bottom to dry the solvent out.

To replace the old oil I put in 600cc of the nice green Bel-Ray Fork oil that you see in the Photo above.

Back on the Frame they go, Its starting to look like a bike again.

The Back Story

This bike was originally purchased by a woman and her husband for some recreational trail riding. I have her name because its still on the title. They bought this bike (the 87) along with a 1986 CR125 (that I also bought) at the same time new in 1987. They proceded to ride the bikes for a couple of years as the story goes maybe three or four times a year. Then things between them went bad and they ended up divorcing in the early 90s. She got the bikes in the settlement. In 1995 She has a new boyfriend or husband and they decide to give the trail riding a try, they went out a few times but it turned out that they were over it. The bikes then sat in her garage untill Feb of 2010. Now the next owner comes along with his teen age son to purchase the bikes and use them for trail riding together. Neither of the new owner knew anything about bikes (and from the looks of just a few of the things on them I do mean they knew NOTHING about them) so the son takes off like he is invincable on the 1986 bike and procedes to ruin it from what I believe is running it without the use of pre-mix, ( I have not pulled the top end apart just yet). The son then decides to play mechanic and started pulling things apart without knowing what he is doing, so there are some small parts missing but was stopped before too long by Dad and saying they would have someone take a look at them. The 1987 bike was run some but at a much slower pace but probably still with no Pre-mix (it still has compression). So the bikes sit in a barn for some time waiting for Dad to have them looked at. It never happened, Son moved out Dad needs to move across country. After another year and a half in the barn now December 2011 I find the add on Craigs list and bang like that, I have two lightly used mid 80s CR125s for super cheap.
