    Hello all I've recently done a full rebuild on my 125 but out of all the pictures I had taken I've not got any of how the balance shaft goes back together. I've got a timing mark on the bottom cog on the balance shaft. Then a mark on the Bottom secondary cog, then the cog ontop of that one has a mark. So they are all lined up... But how do you time that up to the clutch basket and the main cog coming of the crankshaft?

    Any pictures comments are welcome. I'm complete stuck now

    Thanks Jacob

    Any chance of a pic ? havnt got a clue but the clutch main gear will not need aligning. The other gears ie crank and balance shaft I would assume would have a line or dot that has to be lined up other than those two I cant picture anything else that would need timing.

    I'll try and get one. It's all back together now but it's defiantly not right as its rumbling on tick over but is better once revved up. The way you line up the secondary counterbalance gear to the crank gear is through the clutch basket.
    I done piston top dead centre a ligned the counterbalance up with the clutch basket. It's not right though

    The secondary counterbalance shaft is the bottom right cog

    This is where you see the counterbalance marked up with the secondary cog, then the clutch basket connects between the crank cog and the balance shaft secondary cog
    Cheers and all help is appreciated

    Does the rumble shut up or almost if the clutch is pulled ? If so thats pretty normal, cant really make out much from the pics and must admit it looks a little different to what I pictured in my head, Have you looked on line for a manual ?

    Right I've sorted it now :) like a tw*t I put the crankshaft cog on upside down. Which is why I couldn't see a small dimple on it to like it up to the clutch basket with

    This is what it should look like for anyone else who gets stuck

    Cheers for your help though mate image.jpg image.jpg

    Hello. I don't know if anyone will see the answer because this topic is long overdue. I am a mechanic and they brought me a machine from the same engine and I don't know exactly how to set the balance gears. What you wrote is ok but how you put dots on those two gears under the basket. There is a balancer on them, so that is very important. Thank you in advance . How does it work now ???
