Help me tune my 84 R - revised

Is there a huge difference?

I think it was who said that he had to bump up a jet size because it flowed so good compared to a foam uni

The answer is a leaner pilot and move the needle clip up. You need less fuel, not more air. The K&N will allow more dirt in with the extra air. Try it all the same.

I think I disagree with this. If your K&N filter is cleaned and lubed properly it will work perfectly. I don't prefer the foam filters because I think they release the oil from them to quickly and allow dirt thru.

I agree that you need less fuel down low. I'd say your idle circuit is still a little too rich causing your wet plug just off idle. Lean out your needle all the way then tune your air/fuel idle screw from there. The idea is to get the bike to idle for long periods of time without loading up or surging. If it loads up, obviously it's too rich. If it surges and searches for idle it's too lean.

Tim sounds like your real close already! Don't get too settled though, cause it will all change when it warms up next summer!
