Another Bandit running problem post

It's a 1991 400vm jap import with a k&n panel filter in the standard air box and an end can.

The bike wasn't running for a long time but thanks to a lot of advice and info on here and big thanks to ChrisH the bike is now running.

I've put all new o-rings in the carbs. It has 102.5 main jets with standard pilot jets. The needles are second notch from the top and the mixture screws are 1 3/4 turns out. Float heights are about 14.8mm.

Ive read several threads on different forums and the factory pro tuning guide which is all excellent. From reading this I've a rough idea how to enrich or lean the fuelling at different rev ranges.

The bike is hesitant at low revs and very reluctant to rev but it does idle reasonably steadily. It behaves better at higher revs and improves slightly when fully warm but not by much. Still not rideable really.

It needs choke to start when cold as normal so im thinking its too lean rather than really rich.

I've put a video on YouTube. Please could you guys watch it and see if you think it's too rich or lean at the low end?

I'm a novice at messin with carbs but want to figure it out so any help appreciated.

If you are running the k&n you need to lift the needle one slot from standard as they allow more are in at 1/4 to 1/2 throttle.
Main jets are usually ok as stock depending on what exhaust you run.
