View Full Version : 81kz440 jetting issue

I know this is probably a frequent question with these bikes. I've put pods filters and straight pipes on and the bike ran mint with jets of .68. I then decided to go with a bigger jet of .70 but now the bike barely runs. I can get it at a very low idle but any throttle with choke off kills it. I've tried playing with the set screws for a couple hrs and just could not get the bike to run again. My question is what's the best route to go with adjustments with bigger jets. Or should I just put the other set back in.

Why would you bump up the jets if it was running great? Put it back the way it was.
