Re the stalling... I put O2 modifiers on my 1TB V7R. Stops the stalling, doesn't cure the occasional hesitation/spluttering at small throttle openings below 4/4500rpm, if I give the grip a twist, seems to clear its throat. Sometimes a whole ride (100 miles) goes by with no problem. So what's that about? TPS? Anyone else suffering this? It's a '13 V7R that's had ECU/TB replaced, and new Lambdas. 4600 miles, drinks 97 only...

SERIOUSLY? You had the cold start problem where you just literally CANNOT ride away until a minute or two has passed and now you can cold start and pull away without it dying?

INTERESTING - especially since I don't have an occasional hesitation/spluttering at small throttle openings.

But I'm willing to try... all I need is a second Fat Duc...

I have a Fat Duc if you're willing to try. I'll send it to you at no charge to try it out, but I'll need it back unless you want to purchase it. I'll pm you for details.

Hmm, ok,

You've got a PM and an Email, I'm happy to try for the good of general knowledge.

Thanks for posting that. I missed the first time through where Todd noted the 02 sensors don't seem to throw trouble codes on the 13+ V7.

Hmmm, ok, now I really do want to try this.

Just FYI... Based on the AFR data I have, I highly do not recommend unplugging the sensors and riding.

What happens Todd? Is it leaner then with?

I was contemplating installing a pair of Fat Ducs and going for a ride...

But same question as Instg8r - what happens? Would it go leaner? I can't imagine it should (but I guess there are plenty of other things that Guzzis do that don't make sense).

:lol:

Are you going to post your findings Kev? I would like to hear how it works out

I put a DIY oxygen sensor on a 09 V7C, and it helped the idle and low rpm running.

That's one data point.

ABSOLUTELY... will be happy to report back.


And Sign - you know we're talking two different.. oohhhh never-freakin-mind :blink:

The oxygen sensor mod offers great hope. It's the cheapest way of modifying the air-fuel mix. If you make the device yourself its cost is dirt cheap. The FatDuc uses $10 radio-shack components.

sweet looking forward to seeing how the 1tb reacts.

I've run my versions HERE very successfully on the '13+ V7s... but you need two, which puts the cost near the re-flash pricing.

The CrapDuc variable resistor does OK on the 15RC ECU, but it fails miserably on the newer 5AM machines.
