Jerkiness is usually a little lower down. Other things to check are the CO settings and the throttle bodies. Assume you don't have aftermarket exhaust on it? As an interim measure, can you control it with the clutch? I have a device fitted to mine, cheaper than the power commander and you can set it up yourself. But can't remember the name of it. Old age I guess.
Your bike might be a bit too new to benefit from the airbox mod.
If you do your own maintenance I'd try balancing the throttle bodies first and tweek the CO settings. JBX has a very good site to help with things like this. https://www.tdm-yama...ex.php?page=CS1
I remembered! I have a Dobeck techlusion to manage fuelling. Needs recalibrating again though.
Do you know what is the setup such that it doesn't jerk?
I had the ECU re-flashed, it runs very well, extremely well actually. absolutely no jerkiness. the FI now runs as an open loop system reading its fuel data points from a map rather than the Lambda sensor "modifying" the fuel input at low throttle openings. The lambda sensor and its closed loop fuel injection is the root cause of low rpm jerkiness
There is a slight loss in part throttle fuel economy, as the bike now runs at around 0.98-1.05 lambda instead of the 1.10-1.20 previously. ( i.e. more fuel, same amount of air)
cylinder engine
All Fuel injected engines tend to run weak part throttle fuel air ratios, it improves fuel economy and emissions, however on a twin ( with light-ish flywheels) it will tend to make it jerky. the trade off for smooth operation is decreased part throttle fuel economy.
it has all the usual air box mods, but I have dynoed all these before and after. fitting a K&N without adding more fuel will make it worse, much worse. a slight improvement in part throttle can be obtained from changing the FA ratios on the dash, this will NOT however change the fuel delivery when operating at anything more than tickover.
My bike will happily run around at 1500rpm in the higher gears without any problem.
Samios Racing did the re-flash, Spiros who runs the firm is a great bloke, very knowledgeable
