September 1, 201213 yr i recently fitted a new carb mikuni vm26 to my twin shock can't get it running right. Got it from allens and it was supposed to come with a good setting for my bike. its running way to rich called allens there answer was to sent me another tube were the needle goes into a n6 as supposed to a n8. Its still running rich spoke with someone else who has some knowledge and they told me should have changed the main jet first ,its a 125 in it already anyone out there with any ideas? and what size of jet i should change it too?
September 2, 201213 yr Does it pull from idle and than get's rough or is it rich right from idle, also check if the carb is clean, I bought the same carb and had the same problem to find a piece of plastic providing the choke to close correctly. Guy
September 2, 201213 yr Standard settings for a VM26 on a TY250 should be 150-160 main and 30-40 pilot, with airscrew about 1.75 out. Tony
