OK Yall, Here are pics of my air cleaner box mod. I cut half of entry tube off and front lower back portion of air box. Please remember that I have only done CAT mod. Those of you that removed your baffles may need fuel processor.

Thanks for the pics!

Now how about telling us about the Cat mod?

Haaa... What BigDaddyTX Said lol

OK Boys!!! There is a great post already in this forum by the original guy that did this mod. I will do search and send your way or you can also do a search above and just type in CAT MOD.

I posted a reply in that post for the CAT Mod to bring it back toward the top in HOME. You can find it there!!

Hey 11Stryker, I removed my baffles and gutted the cat. I then did something similar to my air box as you did. Seems to run great, but now I'm concerned about not having a fuel processor!

Well if it is not stalling or running really rough, may be OK, But main thing is that you are not running in a lean condition. Pull spark plugs out a few times to check color. Should be light brown. if they are grayish, you might be running too lean and burn pistons possibly. The Fuel processor will make up the difference. I have no experience with fuel processors at all. See the posts on that subject.

no if they are clean with no color, it is lean.....black is rich....
the light tan or brown is good.

 

[dejablu110]

you can find out by doing a cheap dyno run....just a run not the tune

You notice any ill effects with your power band yet

Checked the plugs and they are a light brown. I'm still going to get a fuel processor just so she doesn't run too lean. Thanks for the help!

That's Great news SilverRidge08!! Let me know how you do with a fuel processor! You can help me out in return!! LOL

There's an old school way to check the mix, you can do a plug chop on new plugs.

Basically you swap the plugs, then go for a quick ride. Give the throttle a good hard twist, run it up into the RPM and then hit the kill switch. Pull the plugs and check the color. Looks like new or grayish you're lean. tan to brown you're in the sweet zone. Black and "oily" or sooty you're too rich.

I learned that trick from an old mechanic. You can do it on your current plugs, but it'll be hard to tell if it's rich since the plugs darken with age.

It's also common for the rear jug to be slightly leaner than the front since it doesn't get cooled as much by air flow so it runs hotter. I don't know enough about hte new EFI our bike has though as it may compensate for that.
