I'm having a bit of trouble getting my gsxr throttle bodies to return to fully closed when i take my foot off the accelerator, sometimes it will rest at 0.2%-0.5% throttle so my idle is very lean, rather than at 0% where idle is set up perfectly, if i blip the throttle it will sit back down at 0%

I think the trouble is having the throttle cable at one end of the bodies and the tps at the other so there is slight play in the butterfly rail,

Anyone else had this problem?

Cheers

 

try putting a soft return spring or two on different places on the mechanism and some good quality spray grease
