There really isn't too much left to do without either spending serious money or compromising its all-round goodness.

Dyno numbers (on new engine) are 121.8 hp and 76.6 lb-ft. Those will surely rise slightly as the engine breaks in. As for the weight, I haven't yet weighed it but I weigh parts as I remove or replace them and the wet weight should be right at 400 lbs (based on listed stock wet weight of about 480 lbs).

thanks for looking and for all those who helped me over the years

P.S. Don't take this to mean I am parting with it, it is with me to stay....

very nice!!!!!!!!!!!

[Kev L]

How's the weather out there now? Have you been out on the bike yet? Sorry you missed out on those carbon frame covers on E Bay. The muppets on there have been the source of much discussion recently. Take care.

[tony.mon]

Definitely getting there, mate.....

[Eclectic]

Very nice, sir.

Hi, it that an SP1 speedometer?
Was it difficult to fit as it looks very cool on the firestorm.
Cheers Lee

Almost forgot, Sweet Ride!!

[gilson]

I don't like it at all...... LIE!!!

Lovely job Mick.

[sirch345]

Micky, that is one hell of a bike you have there
You must be very pleased with the outcome of all your hard work over the years. Those figures and the amount of weight loss must make for some very interesting riding I'm sure

Thanks for the descent photo's, I really enjoyed going over them. The more I looked the more mods I could see, and those were only the visible ones I liked the transfer/decals on the side fairing panels saying "V Twin Inside"

Glad to hear you're not thinking about selling her after all the time, money, hard work and effort gone into this bike.

Cheers,

Chris.

Thanks for the kind words Chris

On the downside, my tech was not able to get the open airbox arrangement to work (may try again at some time in the future but dyno time costs money....). The torque curve is quite flat with no dips or peaks at all. The last remaining issue relates to the bike`s ability to handle rapid throttle input at low speeds. While not severe, it does tend to balk slightly, a situation I don`t really care for as the one thing I have rerally grown to like is the bike`s snappy response. MY thinking is that the lighter DJ slide springs are opening too quickly. I am looking at addressing the matter (with some fine-tuning) in the coming days.

Apart from that, she runs very well (and will only get better as it breaks in). The front brake too, is absolutely amazing, very powerful and progressive. I am a very happy Stormer

[benny hedges]

the dj diaphragms springs will definately be the cause mik.
i had exactly the same issue with mine, making it way over-rich low to mid rpm.
i fitted a pair of new oem springs and it made a world of difference.
(took ages to arrive from honda san though)

tbh bud i think you'd prefer the bike if you put it back to standard.
if you want to swap any of your bling for standard parts just drop me a pm

[mik_str]

Thanks Ben, I am touched by the kindness (and selflessness) of your offer, lol

In regards to the slide springs, I have the OEM springs on hand and may eventually try those again. However, as those have a different rate and preload, slipping them back in would require a few adjustments (to pilots, fuel screws, needle,...) which I would rather not do if possible. The problem is not with the fueling being rich at any point in steady state operation (or in gentle throttle application either), but rather a hesitation whne the throttle is opened aggressively (easy to do with an HRC 1/6 turn throttle tube, he he). My theory is that the slides lift too quickly, opening up the intake area too quickly and causing the engine to bog momentarily. By slowing down the rate of slide movement, it should allow the slide opening to better match the engine`s ability to handle the increased venturi size (or area if you will).

I will (initially) be installing a set of modified OEM slides with one of the two lift holes filled (leaving only one open). This should, in theory, slow down the rate at which they open without affecting their equilibrium height (ie. the height at which they settle when the vacuum and spring rate fall into equilibrium).

It`s all theory for now but, as the physics supposedly supports my course of action, it should correct, or at the very least, improve, the problem.

[benny hedges]

let us know how you get on with that mik....
when you think about it, if you run hi compression pistons, you also make higher vacuum which would affect the movement of the diaphragms.
this is why i think the dj kit is a bit haphazard.... sure it's easy to fit, but without dyno setup it's pure luck & flaw.

what pilots are you running btw>>> i'm using 50's atm with a bmc race filter and it seems bob on but i havent had it back on the dyno yet, was going to wait til ive done the pistons - and i didnt want to do that til i saw what tony's ran like with the pistons & cams lol, was worried about them meeting the valves!

[tony.mon]

So little faith......

[benny hedges]

So little faith......

was more a case of seeing if yours smashed itself to pieces before i did mine!!!
come on admit it... you'd do the same if i bit the bullet first!
still havent got a clue what the lift is on my cams though compared to std.

Interesting to hear about the slight balk from a rapid throttle response Micky. Knowing what you've been like in the past you'll will be sorting this out for sure, so you're completely happy with the results

The front brake sounds excellent too.

One thing I now see is you have the TPS adjusted to 430 ohms. Out of interest how did you come to this figure, and what difference does it make

Chris.
