You ask and sometimes you recieve. Im curious what other racer have changed out on the RC390 to make it a better track weapon. I so far have done:

PP race windshield
JRi rear shock level2
GP cartridges completed and on their way to me

Rearsets and race seat +belly pan for clearance ,

Loose as much weight as u can from the bike and stick some proper rubber on . Then its a tune and u should have a very capable bike ..

I forgot i had the PP rearsets. What is this powertronic ecu?

It's an Indian made ecu. Quality seems good but I've been a little concerned on how it determines load (using the injector PWM signal) plus it doesn't deal with the closed loop circuit (anything below 5k
RPM) that I will likely get a PCV and spend my dyno money on getting that setup.

Be interested to see what sort of #s you get out of a PCV. Ive notice there can be a slight hesitation in the motor when going WOT. Almost like nothing and then a powerband kicks in.

Look at PCV testing thread under our sub-forum! Huge gains especially with pipe, K&N, and open air lid ;)
