I've done the step-by-step thing: first a Y-piece, then the Remus end can, then a K&N. The Y-piece definitely made the biggest single difference. The remus can none at all that I could detect, just noiser. After reading about lean fueling, holed pistons and the like, I decided to get the Techlusion R259 fitted. TTS of Northampton did the fitting, which looked pretty neat. On this occasion, they didn't do much in the way of fiddling with it, just set their standard positions by eye (more of which later), and off I went.
Much smoother and seemed to 'pick up' quicker BUT much greater fuel consumption (tank range dropped from 200 to around 140-150 miles) and the plugs looked very sooty. I e-mailed the manufacturers (go to
www.dobeckperformance.com) and they sent through some new, leaner settings and strongly advised me to set it up with a multimeter, not just by eye-balling the scale. This was easy enough (and I'm certainly no electrician, so if I can do it.....
) and lifted the fuel range back to around the 170 mile mark. For those who are interested, the settings I've got now are: C 3.6V, G 0.6V, Y 1.0V, R 1.0V.
I'm getting fed up with the Remus noise (baffle in or out) and will probably re-fit the standard can soon (but keep the Y-piece). I'll do the steptoe CCP mod as well. After those two tweaks I think I'll pay another visit to a dyno and see how she's running.
Too much faffing about for too little gain? Well, probably yes. However I enjoy tweaking the bike and getting the best out of it to suit my riding. But if you want to cover ground quicker and the budget's tight (and you're not into loud exhausts), I'd leave it COMPLETELY stock and save your money for some advanced training instead.
Er, does that help?
