Just curious who is running a K&N drop in or luch box filter, Jet kit, with STOCK Exhaust..?? I would like to know how you like it and what your jet setting are? I have a 2007F and wondered if this is a big improvement over stock? Cold starting sux....!!! Thanks
I did a seach and see there are a few people running this set up, just wondering how you like it or if you would upgade the exhaust to :cheers:
I like that the power band is a little more smooth. I have K&N lunchbox with 20/65/142.5 and Iridium plugs. The only thing I don't like is that the lack of an airbox causes there to be more intake noise. Not a problem for commuting but kind of annoying on a long trip.
Mine is an 07 with a K&N lunchbox, currently jetted at 20/62.5/142.5 and stock exh for now. I'm still tuning mine but it is a turn key engine
I have a setup identical to Worm's. Here's what I think:
Plugs foul a bit more at slow/idle since I sit in traffic (it's my daily runner, lots of idling) during low speeds. I probably need to adjust my mixture screws a bit. Yes, the intake noise is a bit louder, but it does not bother me. Just reminds me that my engine is working.
My cold starting procedure with 20/65/142.5 is the following:
Shift to neutral, kill switch in the ON position, choke all the way on, turn key, crab clutch, hit start switch, engine immediately fires.
Blip throttle. When it reaches 3500-4000 RPM, which is pretty quick, adjust choke to 3000 RPM.
Run at 3000 RPM for about 20 seconds, then slowly ease off choke.
Take off riding. Never stalled yet.
I will mention that my bike ran like hell when it was cold. Turned out to be poorly adjusted valves. When was the last time you adjusted them?
