The CR125 Project: Motor Check up.

Motor Check up.

Here is tonight's motor check up. I got a photo of the motor with the repaired water pump inlet.

Then moved on to cleaning up the outside of the motor cases. Followed by draining the oil and removing the clutch cover and the clutch.

The Clutch hub is in as good of condition as I suspected judging from the rest of the bike so far. There is no wear on the edges of the basket which to me is one of the bigger signs of a motors use and abuse over its life. As you can see there is some oil left sitting on the hub, I cleaned the gearbox out with solvent and wiped the clutch plates clean before putting it all back together.

Next up tomorrow I will finish cleaning the cases then put a fresh coat of engine paint on even though the wear on the side cover is very minimal in its original state.

I also took a moment to put the sub frame on and the foot pegs.
There is a lot of distraction behind the frame so its a little hard to see.

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.
