Do I Need To Remap?

I’m not sure, but I guess it’d be hard to tell without dyno time to see how the fuelling has been affected.
Are the cans new, as in are they still available? It might be worth emailing LeoVince to ask if they recommend a remap or not. They’d be able to sort you out with the correct baffles as well I presume.

 

From the std maps i have seen they are relatively rich even at WOT/rev limit IE there are only a very few cells that actually achieve best AFR for power IE 12.5 to1 so i very much doubt that a slightly better flowing filter and exhaust will make much of a difference.

 

Tricky, can you, or anyone else, please translate that into summat I might understand, please? I ask because, I bought my bike already fitted with an SC Project can fitted. I haven't checked t'air filter, but I reckon its running rich, cos the end of the exhaust is black.

 

Not always a good indicator of general running as idle ...where you see most deposits at exhaust tip is usually pretty rich anyway, the map will have the air fuel ratios AFR set by the map and as i said its pretty rich until high RPM/load so as i said the exhaust is unlikely to lean fueling out much.

 

so, do you think I'd benefit from a remap, either a tuneECU or Hilltop type?

 

Without a decat there will be little change other than volume, You can use plugs as a combustion indicator .....but you have to cut the engine at the RPM/load you want to read and pull them to get any real idea of how it actually running, The other option is to fit a wide-band lambda setup which will give you the AFR in real time that's what i always used when tuning and mapping...but not cheap.

 

The simplest way of checking the fuelling is to look at the colour of the spark plugs. If they are mid brown they're OK; if they are more towards white they are running lean.
