Hi Guys.
I've been off the grid for a few months now. Life's not been the best and with this Virus it isn't improving. To summerise. We had a minor problem with the bike, not related to supercharging, this should have set us back only a couple of weeks. Unfortunately when I came back from my Thailand holiday I had to go into quarantine for 14 days. I also came back to finding my sister was in a hospice and very sick. Because of this Covid Virus I was only able to visit her after the 14 days. Luckily I did visit her and say my last goodbyes and she died the next day from a very aggressive cancer. This has knocked me sideways to say the least. In addition my operations to sort my carpel tunnel syndrome in both wrists have been postponed, and now I've got Gall bladder issues and will be going in for a scan next week. Life's a ***** sometimes. My problems are not life threatening but certainly get in the way. My condolences go out to all those people hurting because of this Covid virus.

On a plus note JE will have some forged low comp pistons to me in the next couple of weeks so I can really lean on the motor with some safety.

What I have found through testing is that the throttle position is limited in every gear. This bike never sees full throttle. 3-6th gear it sees 90% at 3000 rpm dropping progressively to 75% by 5000 revs and finishing at 64% by the rev limiter, and 50% in top gear by the rev limiter. This is the same in rain/road or sport modes. I also found that adding a few degrees of ignition timing was worth about 4-5 hp.
Mods I have done are:
1. moved the clocks forward on the bars, I turned the mount around and cut a couple of lugs off it, it now sits central to the bars centre line, I no longer have to dip my head to see what speed i'm doing. simple mod but makes the ride nicer.
2. chopped 90% of the silencer/muffler away, just leaving the right side pipes and opened the exit pipes out to 2 inch. It now weighs about 25 lb less and it now sounds like a motorcycle.
3. For those who wondered how I was going to manipulate the fuel and ignition, i'll come clean :). I cross matched a Powercommander V and fitted an ignition module. It wasn't straightforward but it worked first time.
4. Supercharging. This is really what you wanted to know! We are up to around 240 whp and 240 ft'lb of torque but I'm not going to push any further until I get those JE pistons in the motor. I've seen the OE pistons and through my experience I feel they won't take what we want out of them engine.

Clocks are just a couple of inches forward but it makes a huge difference.

Looks stock

Not stock.

Big bore exit pipes.

First run modded pipe verses modded pipe and remapped with PCV. Really only brings it back to where it was stock but with a throatier noise and a big weight loss, but still a great looking pipe.

Supercharged Power. Development will commence when we beef the motor up with the JE pistons. The curve was so strong it alarmed me, i'm not brave enough to lean on it without the pistons.

I know you will have lots of questions. But as i'm laid up I will try and answer quickly. Keep safe everyone its not a nice world at the moment.

Knew it!! 😆

Good to see you posting again and sorry for your troubles. What kind of boost are you running now, 8/9psi?

I’ve also got a set of cams being ground. Stock is 9.2 mm inlet and 9.6mm exhaust max lift. I’m hoping to get near 11mm out of a regrind. I will run them on a stock engine to check the gains and the supercharged one later.

First of all, my sincere condolences, and sorry to hear you going through hard times :(
My first thought after reading o.p. was "well.. as far as i am concerned - fix the throttle limitations and i'll be a happy customer without anything else added/modded!
Not sure i want more exhaust noise to be honest although i wouldn't say no to a massive decrease in weight from an aftermarket system.
Another pet peeve is the "chopped off" look of the rear end. In my eyes it really needs the fender moved up. I am quite convinced that "all" it would take to make it work is to brace the stock fender and use the pannier mounts for stability.
Best looking rear arrangement thus far IMO is MrPix's
