14 tooth on 1100 evo

[Uncle Bob]

I'm considering the 14T mod also, as my rough running at low speed wasn't cured by a Rexxer flash and O2 sensor removal. The chain might be a tad loose too. Ultimately I'm still hoping (maybe foolishly) that there's a 'sweet spot' where everything comes together and this bike is brilliant....

I went 14t front before rexxerr flash, the feeling low down was better before the flash but night and day different after the flash, so get that 14t front sprocket and give it a go/

Yeah I think I've got to at this stage Chris.

I spent quite a bit of time....and cash getting mine to run right, although it has to be said even as it was when I got it it wasn't terrible or unride-able or that.

At present mines sits like this:

1. Power commander V
2. 14t sprocket......soon to be +3 at the back
3. Servo valve delete
4. MWR Race air filters plus power up filters
5. Stock exhausts and catalytic converter delete
6. Dyno'd and dyno setup for more power and correct A/F ratios

It runs well, I can let drop to 10/15mph in third without any hunting issues if I want. I dont really do that tho, going through a village at 30 mph in second doesn't need the clutch slipped or anything. In fact I hardly notice it anymore and i'd probably get a shock if I went back to stock bike.

Only down side for me is that a fair bit of the engine braking has been dialed out. which I do actually miss if i'm scratching, I now need to apply the brakes occassionally

Really disappointed for you that you're still having problems, Bob. Did you go back to Neil for his thoughts?

As with Chris, I'd fitted the 14 tooth sprocket before the reflash, so I've no experience of the reflash on its own. As Chris said, the combination of the two transforms the low speed running so I hope you feel the benefits too. Let us know how you get on.

Thanks mate, I am too. It's a bit of a mystery, as it really did improve immediately after the reflash and during the next 300 or so miles?!

Neil was at a loss, but did suggest that it could be chain slack manifesting itself as dodgy fuelling. This doesn't feel quite like that though, and it seemed to become less smooth really suddenly, like between rides! Unless the whole axle has shifted...?

The 14T option sounds relatively cheap, and I don't think I've got anything to lose by trying it.
