Hello I have a 2001 Yamaha blaster the only mods I’ve done to it are a tors delete, fmf fatty pipe and turbine core 2, my elevation is 830ft after a riding trip with a Chinese carb the bike didn’t want to idle so I rebuilt the oem one and it wouldn’t run the same so I bought Jets and went down from 290 and the only jet that felt as good as before was a 220 jet but everyone said for a similar setup I have it should be around 280 so am I doing something wrong? The spark looks good and I’m not really sure what else it could be thanks!
