K@N air filters
what is the secret to getting a '79 to run well using triple K@Ns. My stock except for a 6 into 1 kerker just doesn't want to start. I live at 4,500 ft. elev. and once started it runs fine but at sea level I have to cover half of each filter with tape to get it to run.

Re: K@N air filters
Could be the choke setup is not working properly or even dirty idle jets.
What jetting are you using with the K&N filters.
Some great info from Mike Nixon on elevations changes and the CV carbs.

Re: K@N air filters
Your hard starting has nothing to do with the K&Ns. These things are notoriously hard starters if the carbs aren't, as Steve said, perfectly cleaned and the accelerator pump adjusted and working. Separately, if your carbs aren't Stage 3 Dyna-Jetted or fitted with 80/120 stock-type mains, then the bike won't run close to right, once started, with the K&Ns. You MUST have the carbs completely clean and functioning and you MUST verify what jetting the carbs have before doing any further evaluation.

I live at 3,500ft and have ridden through the Rockies near my home at 4,500ft and then down to sea level with no issues from a stock setup. If they're clean and adjusted properly the carbs shouldn't cause you any problems.

Your K&Ns may not create enough intake vacuum for the CV carbs. Replacing the original airbox and filters on a CBX is always a gamble and necessitates retuning/rejetting of the carbs.
