Hyosung gt650r efi Throttle Problem
« on: October 03, 2017, 03:19:42 AM »

Heya Hyosung buddies, i seem to have a persisting problem with my hyosung gt650r efi 2011.
Bought second hand privately, only had 1700kms on the clock. No problems with the bike after putting on 3500kms on it as well as a failed attempt to  unrestrict it. Stripped the Torx screw and came to terms its not worth the insurance problems. There was no damage to any of the restriction.

Now i have a throttle problem that come up recently, 1 month after attempt unrestrict.  Ive changed the spark plugs and still persists.
My issue is travelling down the high way about to hit the power band 6-10rpm the bike will choke and spatter up there.
Low rpm i dont have an issue. 3,4,5 gears power band are the same issues.
This problem happens when i dump the throttle at the power band. Im guessing its irregular air flow or my ecu is f$&Łed or theirs a vacuum in my tank.

My ridding style is agressive around corners and i tend to flog the shit outa it to a point of being a sports bike not inappropriate use for damaging the bike. Faster wear with harder riding.
Just adding that there.
Any clues? Cheers fellas

Not sure if this would be much help, but maybe take a quick look at the TPS, should be between 1.23 and 1.25 IIRC. There are plenty threads here, and it's simple enough to do even for a noob like myself!
