Okay a while back I started this thread below:-
I have posted the update for that thread as this new thread, it made sense to me.
Simply, I had my uk 929 with 24 k on the clock in the garage for some work being done, including service, mot, new Pipewerx end can, exhaust work, power commander v fitted, dynoed and tuned up, as well as front forks new seals, bushes and oil, the works etc.
Attached below is a picture of the end can, and the all important dyno chart.
Whilst I remember, the bike has had new oil, and they have used Motul semi synthetic. I put this info here, as neither in the Honda owners manual or the official service manual, does it specify whether to use semi or fully synthetic. The tuner's take on it is that semi is best for a road going only Honda of this age. I hope this information alone is of use to people. There is perhaps a little controversy over oil etc. in some threads. I am fine with semi synth.
Finally, and most controversially, we have the dynoing and tuning work results. The bike was dynoed with the exup valve and flapper intact in the air box, i.e. stock positions for both. It was dynoed with the flapper removed, exup intact. It was dynoed with flapper intact, exup removed. It was dynoed with both exup and flapper removed. All with the new end can fitted. Which position yielded the best results according to the tuners? The stock position, with both exup and flapper intact. Otherwise, there was apparently a large flat spot at 7000 revs, which couldn't be ironed out. It was also fitted with a k and n air filter too.
I was surprised too. As the tuners said, it was not typical. So the chart below shows the blue current map on the pc v after tuning, and the red previous map before tuning - I hope this makes sense.
The picture of the can is just for your perusal, I hope you like it, it sounds very good, particularly with a bit of power on.
In terms of the bike, I have only had it back for a few days. The fuelling is definitely different, you can feel it straight away, the clutch work you did in low gear at low revs just isn't needed anymore. It feels even more linear than it did before, bearing in mind how Honda's put their power down. Still early days, not much more I can say at the moment. The tacho needle jumps around now a little on idle, not like previous where it was rock solid once warm, but I am guessing that is the pc v doing its thing.
Be very interested to read any opinions. I hope this is of use to people.
