if you get the lectron leave the intake boot (between the carb and airbox) on and put a k-n on it . why? the tube gives it a ram air efect . you can take the airbox off though.

Neither carb will work properly with a direct mounted filter. I'm a big fan of the lectron carb, just putting it on gives it huge gains. You will need to leave the stock intake boot and mount the k&n at the end of the boot as SAM stated. Wouldn't bother using the airbox unless you're going to going through alot of water & mud. Just make a bracket to hold your intake boot & filter. For more info on the lectron see hpresearch.net & talk to eric or randall - both very knowledgable.

 

leve it in the air box just up date the intake boot

 

how do i update the intake boot ??? rj

 

Get one for an 04 or 05 from your dealer

 

I have run side by side direct mount air filter direct mount and in the box at about 4000' elevation and the difference was incredible!

I know there have been a lot of dyno runs and comparisons but, I just am having a tough time getting away from results I've seen first hand.

I haven't tried the new air intake so, maybe that's the key???

As for CDI's - First. . . remember the old rule. . . you get what you pay for!
Do a search for threads on CDI's - There is plenty already out there - no need to re-hash.

What kind of bike do you want to build? Don't expect a CDI and a carb to win the races. A good exhaust, CDI, and carb / air filter package should net you some really impressive HP gains but, a high compression piston and a set of more aggressive cams will allow you to blow the doors off you bolt-on buddies.
