    I keep reading stuff about Brentune, I sort of understand what it is but would someone mind filling in some details?  :084: In particular, would there be a benefit applying it to a stock 2017 bike?  :187:

    Yes and no...it will indeed make your stock bike better....but to get the best out of a Brentune flash whether stage 1, 2 or 3.... you'll need a decent set of headers and obviously in turn, this will remove the cats. Then the engine will be able to breath as it was originally designed. Gains in rideabilty, smoothness and midrange torque are significant. Any top end gains are a bonus. There are other things which make the bike a little better such as cooler running etc. The tunes can also be tailor made to your requirements if you so choose.

    The RR versions of these engines make well in excess of 200 cankshaft hp, the XR engine, although very slightly different can be tuned for significant increases over the stock ~165 crankshaft hp.....but ultimate hp isn't the main gain of these mods, the way the bike rides and performs at normal rpms is the best change....lf we're honest, very few of us ride around at 8k+ rpm for any length of time during a normal ride out.

    Thanks for the reply and info, that's what I wanted to hear, I'm not looking for top end, just a smooth ridable engine with as much mid range as is possible for a tight budget.. :084: well more like the tight wad I am.  :008:

    Probably need to get out for a good long ride before I make a decision  :002:

    I have Brentune on my Gen2 now and for me it has made that bike better. There is however some anxiety about voiding the warranty and it is not at all suer customisable.
    On my Gen1 I used a Rapidbike Evo/Racing module which also improves fuelling, etc, it is much more customisable and could be removed if the bike had to go into the dealer. So, for me that is a better option but sadly they could not make a module work for the Gen2.

    I wonder if Jordan's Bikes is any good, it's near Jems and they do tuning, it's a pretty reputable shop otherwise and their prices are fairly cheap, I think they only wanted like 280 for a jap, 350 for a euro bike

    Edit: just checked, their website says 480 for a BMW... Ouch They do do quick remaps on japs for 300 though so I wasn't far off.

    Try using 99 octane fuel . I have always used bp ultimate 97 thinking it was the best  . But recently I tried Esso 99 octane and the bike is definitely bit  more lively ( gen 2). When I first got the gen 2  I looked at getting a brentune, but as time and mileage has passed , the bike for me does not need any engine improvement. As with my previous gen 1, the more miles you put on the engine, the better it gets. At 6k miles my gen 2 feels like an improvement to when I had it new.

    Whack some 99 fuel in when you are on empty and see what you think

    There are plenty of people who decry buying the higher 98-99RON fuel, but I and pals on holiday in France and Spain can state that after several years' experience - get better pickup and mileage from the higher octane fuels.

    Harder to identify on short UK runs.

    I tried all types of fuel, Regular morrisons, sainsbury's premium, shell regular, Shell v power, esso supreme, whatever, for me it makes absolutely 0 perceivable difference to my fuelling. Sometimes the bike feels different from day to day on the exact same tank of gas. I do see some variance in mileage but it's minimal compared to my throttle mood or the types of roads I happen to be driving on.

    I ordered a Flasher and Bren Tune during lockdown, and it does make the bike feel nicer to ride, but that is so hard to quantify. It does depend on what you are after as it's not cheap to buy as the Flasher has to clear UK Customs. If you are after a major change in the bikes behaviour Black Widow Headers are a better bet at approx. £400 and I found they were pretty good, although there are more expensive versions around that some prefer. You will definitely needs some new headers to get the mid-range freed up and can easily gain 10hp in there, and around 5hp at the top. But it will be a bit noisy  :164:

    But it does work on a stock bike - I ended up running a Bren Stg 2 with standard headers and it ran really well. I could leave it in top and ride around at 30mph, sit at 70mph and still get over 50mpg or drive it hard over 7,000rpm and it was pretty damn quick. I was happy like that. I have since put the standard tune back into my Gen1 and then re-used the Flasher on my Gen2 so only had to pay £295 for a Stg2 tune - again the bike is box stock but it just runs nicer with the tune in it, better throttle connection and low down drivability.
