Well I'm officially a fly puller, after two years and almost 30,000mils. later...
I had the bike torn down for winter maintenance, clean K&N air filter, check all fasteners under the plastic, ect. and figured WTF..(99.9% who pulled the flies are happy.)
Easy peasy, screws came right out no heat with old worn out short phillips screwdriver?

After reading all the horror stories, go figure?
I'm running a K&N airfilter, Two Bros exhaust with their Juice Box installed.
I have the Juice Box turned off except for a very little fuel added during full throttle high rpm operation. When I ran the Two Bros suggested map the bike ran very rich, fuel mileage was poor, very poor.
I won't get a chance to ride for a couple weeks too see if the Juice Box will need to be adjusted from my current settings.
I have read fly's out OK except a little lean in upper RPM's, so I'll run my current map setting to start.
If anyone is running, K&N (or BMC) air filter, TB exhaust, fly's out, with their Juice Box installed, care to share your settings?
When I get a chance to ride I'll post my thoughts and Juice Box settings, but most important how much better the C14 will run.....
Is it spring yet?
