I've just put a new cylinder, piston and stator on my NSR 125 1992 italian import, also cleaned the carb. Everything has been put back together to the manual spec. I went to start it up and its just turning over, sounded like it was going to start a few times but nothing. I'm getting fuel and spark, the compression was 90psi but its not been run in yet as it won't start after the rebuild so expecting that to increase once ran in, is that right? Any ideas what it could be? Also the rev counter needle is bouncing when I try and start it, not sure if that could mean anything. Any help would be great. Thanks.
