2009 1078rr throttle resistance and surging

Hi all, my friend just picked up a 2009 1078rr. only has 9000 miles.

I rode it and it feels like the throttle has a lot of resistance, too much. The throttle body return spring has already been disabled.

When the bike is off, twisting throttle feels normal. but when the engine is running its a lot harder to turn. is this normal?

when applying throttle from it being closed, say going into a turn when braking is completed, the throttle is like an on/off switch. kinda scary actually, it's way too difficult to smoothly apply power. is this normal?

thanks everyone!

Same bike, same year. Yeah it's normal. Not sure what you mean by harder to turn when running but definitely like an on/off switch. Microtech from XBikes is one solution but an expensive one. That plus disconnecting the return spring on the side makes it a pleasure to ride.

Cheers

great bike, I have the same model,now you have to spend some DOLLARS,Mine is smooth as silk,check the cable adjustment screws,there should be no need to adjust the springs at all,I have hade to sets of throttle bodys on my bike ,The first set i stuffed up totally,i know every inch of this bike,only adjust the tps with software and the air bleed valves,unless someone else has tampered with them.tps first.then read all the threads on this topic,your choices are microtec from chris at x bikes or pc5 with race ecu and a dyno tune.runs smoother than the jap bikes.

cheers eddy

Thanks for the advise everyone! My friend was nice enough to post this question for me...he's cool like that. I'm completely new to the 1078rr's personality...MV Augusta in general...and the attention this bike gets! It's the most gorgeous bike I've ever owned. I really have some studying to do.

I figured I'd follow up with what the fix was for the surging issue. I ended up getting the TPS reset and throttle bodies balanced. Good call guys! The bike feels much better now. Thanks again for everyone's help.
