m82s Posted August 5, 2012 Author Report Share Posted August 5, 2012 Ok so I have got a little further but bad weather meant calling it a day. I have done a few more bits and managed to get the bike to start after removing and cleaning what is also a new carb but the bike had been stood. I cleaned the needle which looked like the only dirty part. Rest was pristine and throttle now flicks back nicely but the bike will not idle smoothly and requires choke to tick over. I'm told something about the third small jet? How do I clean this please? It's on bottom of carb but don't want to damage it as its a brand new dellorto replacement. I also see a very small breather on side of carb which looks like it should have a pipe on it of very small diameter but it doesn't? Lastly, I have done 2 1/4 turns on lower smallest spring loaded screw. Any idea what the larger acre is in middle of carb on same side and what is position should be please? I assume one is fuel and one is air and is this why it doesn't run as that screw is fully in? If not it must be that jet doodaa! Sorry I'm a newbie! Big thanks people!

st matt107 Posted November 16, 2012 Report Share Posted November 16, 2012 Hi, Yes they should have chain tensioners on the underside of the swinger. Dragging clutch is kinda common I think on these bikes until the oil warms up a bit so I wouldnt worry too much about that unless it persists when the engine is nice and warm. Plastics are a real pain to get especially the rear mudguards and seat. An 80cc item MAY fit but a bit of tinkering will no doubt be required. The air filter had a black plastic housing that screwed to the sub frame I think? Sorry not sure about oils and stuff? Quote Link to comment Share on other sites More sharing options...
