older RM125 rebuild

how hard is it to rebuild an older rm125 (i'm guesing from pic's that it is around 79-83?). a friend of mine got it for free, a neighbor gave it to him, it had been sitting in his garage for a few years (i think it was his grandson's or something and they just didn't want to deal with it anymore) but anyway i grew up riding dirtbikes z50r,dr100,and kx250, but i have been out of it for a while and decided to get another kx250 in the near future. my friend has never rode one he has always had 3 wheelers, and said if i help him rebuild it i can use it whenever, and if he decides he would rather have a four wheeler instead the bike is mine. my question is can a couple of guys that have minor motorcycle repair skills and a repair book completely rebuild an older dirtbike, or should we just go in halves and take it to the local repair shop.

My vote is do it yourselves, they're easy to work on. Have you got the manual already?

Re: older RM125 rebuild

i am picking up the manual this week and then over the weekend we are going to go through the parts and see if it is all really there in the box like the guy said. the suspension, brakes, throttle, sprockets, chain and that stuff is still on and seems to be working fine, and the bottom half of the motor is actually still together, it is just from the piston up we need to rebuild (the piston is sticking out of the crankcase, and isn't seized up) we drained the fluids and they all seemed fine, no water or other crap, but when you look down the cylinder it looks like there is some water so we will be pulling the crank cover off to see what's doing in there first. any help/tips or sugestions will be very helpful. thanks for the posts.

Unless your into old bikes or else forget it. It'll cost a bunch to make it like new. And then after all that it will still be a 79/83 RM. I know from experience. If your in bikes put your cash to better use
