I have just fitted race baffles and gutted the CAT on my '06 and I was wondering if anyone else had done this without fitting a PCIII. The bike is running on stock air filter and one slight concern I have is that, with it now running leaner, is there a risk of valve burn. The bike is used for commuting and the odd track day so does not get massively thrashed.

If a significant risk I will fit a PCIII, but being as the exhausts cost me less than £100 all in, £300 seems a lot unless it reduces the risk of serious engine damage.

Thanks

no ... you dont stand chance of it. you would have to remove pipe all together pretty much to burn valves. i ran my bike this way for year at dragstrip. i didnt run pc at all. pc will help some in performance. its good idea, but you can ride it without for while with no problems

there is a way to fatten up your fuel curve by going into a menu on your dash controls...do a search or hopefully someone will post a link. best of all its free.

yes u can adjust the CO levels of each cylinder from dash. you have to unplug fuel tank, run wire to i think like pin 39 of ECU and ground it to get it into the correct mode. there is thread on it..but its long and covers 02 models in first 15 pages or so then 04 and up models.

Thanks for feedback 1longR1 / 2005r1/raven - Setting the CO2 levels myself sound like a recipe for disaster and I don't need any more power so as long as it stays smooth on the power delivery I am going to leave everything as is.

Cheers
