Hello everyone.  I have a JLO 400 and recently found a used vm34 mikuni carb off a honda 400 quad.  It seems to be loading up alot.  I was curious if anyone knows what size jets work good with these motors, what people have had luck with, or what size jets came from the factory?

Hi, Matthew;
If I remember correctly, the carb on the 400 was smaller- maybe a 28mm. I think the last one I took apart had a 135 jet, but with the 34mm you'll have to "trial by trail" as to the best size.
Good luck
