Hi guys, forget the bent crank, that was just what happened to the last 2 stroke engine I pulled apart. I have managed to get it running, It was the round seals inside the crank case had popped out, had to get bike mechanic to work it out but its all good now and im cheering! Thanks for all your advise and help, hope I dont need to much more in the future! Sincerely, Tony

Unless it was bent before which im pretty sure it wasnt and I didnt actually pull the case apart, just the cover off the side. and no pics to show sorry.

How ya going? Done a compression test and came out with 105 PSI, have got spark, sprayed engine with WD-40 and turned it over quite a few times and no leaks that I can see. No smoke comes from anywhere at all. In high school I had to pull apart and fix a 2 stroke lawn mower, I replaced rings and afew other things and it went first go and it ran for a little while then stopped and wouldn't go again. After pulling it apart again I found I had somehow bent the crankshaft. Could something like this happen to the bike because it should run as far as I know and it did but it doesn't now. Tony

Thanks for replying so quick. I didn't even think of that though I have ordered a new head gasket already, just waiting for it to turn up. If that doesn't work i'll try the others. Thanks again for your advise much appreciated.

Hi my name is Tony I have owned my '79 YB 100 for over 10 years. Its the first bike I learnt to ride and been my only bike since. I too am trying to get mine running again after sitting outside for 5 years, it was seized but not any more, I got it to run this morning but it revved off it's nut. I have changed things like the idle screw and throttle tension to try and lower the revs but now its not running at all, and I have reset things I changed back to around where they were. I have no settings for any thing and if someone could email them to me it would be appreciated! Email: [email protected]
