i have a 86 350X, it seems to be running kinda ruff, i bored it 60 over, k&n filter--no air box- with a mikuni 36mm, i just put it back together a few weeks ago, it dont have the get up like it did when i redon it, it had a different plug in it than what was supposed to be in it, so i changed it, it act up mainly when you start winding the motor hard, any ideas. im stumped, i have tried just about ererything

 

what does it do when you wind it up sputter? maybe clean carb or rebuild it or maybe ajust the needle valve i think it will have to do with the carburetor hope this will help

 

yea, part of my problem was my coil, and i had to go one size bigger on my jets because i took my airbox off and put a bigger header pipe. it runs like its supposed to now
