Im sure this has been answered somewhere, but, has anyone installed a BAK w/o a PCIII? Just a stock set up with pipes and an ECU adjustment, and what were the results? Thanks for any info, Im wanting to do this, but dont have the $ to shell out right now for a PCIII[/emoticons/emotion-1.gif]

Yep, BAK can be done with an ECU adjustment along. The upside is definitely the cost savings. The downside(s) is that with your cost savings you'll more than likely be guessing (multiple plug checks at different RPM ranges) as to whether you're runnin' lean or not.

hey python,
if you have found a special ECU-setting with stock-setup that works fine, please post it! i'm interested in this too but i don't have the time to check the plugs always because i need to ride the bike often (have no car. is there any way to check the plugs without removing the gastank?) so i didn't do the mod yet.
when is it better to screw out the plugs? with warm or cold engine?

I live in CO. at about 5700 ASL, Im running Bub chambermaids with ECU settings at+4 on both cylinders and it seems to be very happy here, as far as the plugs, dont know how you would check w/o removing the tank, you can get to the outside 2 but not the other 2, Ive checked them several times and they are all a nice light tan

I've got the BAK with V&H's Propipe, with no PCIII. My stock ECU settings were front cylinder -4 and rear cylinder 0. After a couple of plug checks I'm running front cylinder (CO2) at +7 and rear at +3. I know people say the rear cylinder should be richer (because hotter cylinder) but these numbers give me a nice tan plug for both. I have just a horn cover on the left side, replacing the scoop, so maybe that gets more air to the rear, I don't know. Power feels good with these settings. The biggest boost in power I've noticed came after adding the Propipe. I have no problem getting to the left side plugs by just using the stock plug wrench that came with the tool kit. A little tight but not tough.

Actually that right side box's big function is to direct more air to the rear cylinder.. that's the reason for the angle fins inside.
I know alot of people who have pulled it without problems though
