Kingcat Setups/ low end bog

I have a 2005 Kingcat 900 EFI

I just put a speedwerx single pipe on, and a slp can.
Since I switched the attack 20 around Saturday, i run it through the field a bit to make sure everything was good. I have a low end bog now. Is this the difference in the altitude? I was at about 3600 feet, and normally ride Kings Hill/Lincoln areas. I checked my plug color, and they were a nice brown.

What setup works for clutching and gearing. I have the stock weights and springs in it still. When i purchased my can/pipe, it came with a speedwerx clutch kit. Is this any good? I have a 43 tooth gear for the big gear, and 19 on the small one. Do i need to regear, i saw a post somewhere where there was a problem with a KK jumping gears??

The tech from speedwerx said I should be fine running the can/pipe setup without a aftermarket efi box. He said if it runs a little lean, to unplug the ethinol plug. My question is, where is the ethinol plug.

I am looking for a setup that is pull and ride.

Thanks

Ok, cool. Thank you so much for the info.

I was afraid I was a bit lean at the lower altitude. Didnt run it much, just 3-4 passes across the field. Just enough to chaise the whitetails and geese off the field.

What are you guys running for clutching? Which springs/weights/gearing?
