Is my engine running to lean? OR?

[darrsi]

My guess would be u might need a carb balance and possibly a dynojet kit as u have altered the back pressure with an after market Can and a high flow filter ? I have a stubby exhaust on mine and it runs ok with the baffle in but not great with it out, haven't even fitted the kn filter yet as I'm guna wait until I get it balanced.

Firstly, it's unneccesary to rejet these bikes, i've tried and it simply didn't like it, so i had it put back to standard.


Secondly, balance the carbs after you fit a K&N, not before.
