Hey everyone, I have a 1998 RM125 and was hoping someone could help me out with some problems it has. First off, the chain snapped while riding last year and put a small hole in the casing in front of the fsprocket. It's very small, maybe .4 -.5 cm big. I asked around and a lot of people recommended i try JB Weld. So i did, and its held all winter, and I have now started it a few times no problem. Do you think this will hold up at all for a ride? Is it just a quickfix and should I look for a new case? Also, I bought the chain to put on the bike, but when i removed the nut on the rear axle I found my axle seized..I mean it moves forward and backwards along the swingarm on the side i removed the nut from, but it will not budge otherwise. I have tried all kinds of lubrication products but still nothing. I have put a block of wood on the axle and tried to hit it out. I am now waiting for a brass punch from a friend so I can try that. My fear is damaging the swingarm from hitting it too hard. Does anyone have any suggestions/experiences/or advice on this? Any help would be awesome, thanks!
