So I've been searching all morning and can't find any info on this...

Yesterday I started my 01 f4i and got a throttle position sensor code, and the bike runs like crap. I haven't done any diagnostic yet so it could be a bad connection or broken wire, idk.

If I do have to replace the throttle body I was thinking that I'd get a set off a 929 but wasn't sure if they'd fit or if there's any benefit to this (is it worth doing). Does anyone have any info on this?

I seem to remember about a year ago someone asked me for some measurements on one of the CBR forums because they were swapping to some 929 throttle bodies but I can't find the post.

Anyways, if anyone knows anything about this please share.

 

there wouldnt be any benefit. replace the tps, not the complete system and keep riding.

 

As far as I know, the TPS is not intended to be replaced by itself. I'm not aware of a place where I can buy just the TPS, if you do please share.

I was just asking about the 929 throttle body because if I'm going to buy a throttle body anyways I figured I might as well look into upgrades... And I know the 929 throttle body is 2mm larger than the f4i.

I left work for lunch and the bike ran fine, no FI light. That got me thinking and I remember last summer I turned the idle down (evidently too low) and the same thing happened. First I got the FI light and but the bike runs fine (not sure what the code was), then I turned the idle back up and the FI light went off, then I get the FI light back on with TPS code and it runs like **** briefly... Now it runs fine.

This would make sense because that's the exact steps I went through this week turning the idle down then back up...
