    Hi Rucksta & Locky

    I am not anticipating the same kind of bike notoriety here, ... Relief!
    To my knowledge there are 3 active HPN's this side of the country, mine should be the 4th and the white one in some of my pics will be the 5th. Don't see any of those fella's "scouting for crops"

    GSD4ME I should be able to give you some Lynx feedback real soon ;-)

    Boxa'bits basically the alternator fitted fine but the rotor that came with the ignition kit was not a good fit and when bolted in place it rotated elliptically. The rotor itself is fine as in circular not elliptical, but because it is slightly too narrow in diameter at the insert, it gets pulled slightly off centre when bolted up causing an elliptical rotation that brought the rotor arm into contact with the hall effect sensor.

    I'll try a couple of photos this one shows the rotor in the alternator.

    Here is one of the rotor out of the alternator
    [​IMG]
    The screw driver is pointing to the section of the rotor where the diameter has been machined a bit too far.

    We decided that rather than trying to machine a new rotor we would try and move the hall sensor (not shown above) a bit further back from the rotor. This involved machining the bolt holes slightly so that it could be pulled back and then the bolts locked down to hold it there. This worked and the magnetic sweep arm now clears the hall effect sensor.

    While at the workshop today a bike arrived having been shipped from the UK. It's an R80g/s with genuinely less than 230 miles on the clock. It arrived in a BMW Motorrad crate. Hmmm I thought, they have gone to a lo of trouble to pack t up well. There was an inspection point in the side of the crate so of course I had a look. Wow what a beauty, it really does look brand new. According to Dave the new owner bought the bike unseen, well apart from photos. It was a genuine mileage and has been given a cosmetic restoration as needed, ie rims polished etc..

    I helped Dave unpack it and wheeled it into the workshop where I tried to snap off a few picture to give you an idea of how nice this bike looks. The new owner will be pleased, but he hasn't seen it yet!

    During this week Dave installed the wiring harness, the Yamaha indicators and made brackets for the indicators and rear seat rest.

    The caliper adaptor bracket finally arrived from Schneider KTM in Germany

    [​IMG]

    But there is a problem ! It amazes me that you can pay top dollar or in this case Euro 88 of hem for an adaptor from a professional business only to find that it doesn't fit out of the box!!!

    [​IMG]

    You can see the top of the caliper adaptor won't seat over the bolt hole unless a little filing is done. Thankfully it is an easy fix and at least the rest of the product is well finished and robust.

    Next problem, the adaptor is for a 320 mm rotor and I have a 300!
    I went down to see the local KTM dealer but they had no stock of 320's, however I was in luck one of the salesmen overheard my enquiry and caught up with me at the door. He had a 320 rotor in his spares box at home and would be prepared to sell it to me. The next morning we met up and I purchased a nice second hand 320 KTM rotor. We were back in business.

    Here you can see the Vapour speedo cable pending attachment.

    Next the battery was installed and all the lights and switches tested.

    I can't believe it I just missed out on an HPN water tank aaaaghh!
    Another HPN owner Mike has had this gem sitting in his shed for ages.
    But BJ found out first (that's the owner of the white HPN in progress)

    [​IMG]

    It would have fitted in so nicely between the rear fender and the battery.

    Oh well I will have to wait for my order to come from HPN, unfortunately it could take a while, they have not yet acknowledged the order and that was sent almost 3 weeks ago, groan...

    Mike has just come back from Europe, he visited HPN and spent a morning talking and being shown around the workshop and numerous store rooms. It sounded like a veritable Aladdin's Cave. There are maybe 20 works in progress, shelves of inventory to drool over. Spare frames suspended from the ceiling by the score. Numerous race bikes one from each year of competition. It just went on and on. Apparently throughout this visit the phone could be heard ringing in the office but of course was consistently ignored. H&P are working for the love of it not for the $ so they're in no rush and the phone well if it's important they'll ring back.

    Anyway my disappointment at missin out on the water tank was soon forgotten when Dave announced we were ready to see if there was fire in the belly!

    Now Dave has built up many many engines over his career. His whole working life has been in the MC industry many of those years working for manufacturers racing teams in Europe and Asia. This stuff runs in his blood, he is related to Burt Munro of NZ, that's right "The Worlds Fastest Indian". (Dave if you're reading this forgive me for blowing your horn, but some one has to do it. ha ha)
    What I'm getting to is that it started up willingly on the third turn of the motor. Oh what a sweet sound!

    About 4pm with growing certainty that I would be riding tomorrow morning I had to leave Dave to it. He was putting the finishing touches to the wiring harness / subframe connectors and was then going to fit the tank and balance the carbs.

    Come and pick her up at 8am tomorrow he called!!!


    Yeeeee Ha!!!

    Do you use the standard G/S single seat with the HPN tank?

    Yep, or the double seat. They both fit the same.

    Thanks Wrangler. My standard G/S single seat does not fit my HPN tank snugly. Will have a look again.

    Do you have permanent tank mounts welded to your frame or do you use the clamp on mounts? The clamp on mounts take a little experimenting (or even bending) to get just right, so play with them a little bit. If your mounts are welded on then I guess you're stuck with what you've got, but can play around with the rubber feet on the bottom of your seat. Make them thicker or thinner to adjust the position of your seat. I think the locking tang at the back is adjustable a bit to scoot the seat forward or back. I know it is on the later GS saddles (not G/S).

    hi John
    please look :http://www.advrider.com/forums/showthread.php?t=266100&highlight=fred+powell&page=43 :page43 but I'm sure there is more about him in the same block and there are also different ones about him.
    that's the the only real desert racer in WA I know and Fred still rides that bike today.
    as soon BJ's bike is finished we three should take a ride down south and catch up with him, I never met the bloke but some older club members know him in person.
    cheers

    The owner of the 223 genuine miles R80g/s was there, Steve from Boyup Brook.
    [​IMG]
    He plans to put a 43L tank on it for range, some knobbies and then head off outback. Sounds like great ride Youanmi mine, Sandstone, goldfields etc. This bike is going to see a lot of red dirt!

    The other HPN in the picture belongs to Mike, it has the single headlight and the Paris Dakar decals

    This is Dave next to the subject of this thread the 1st HPM, Kudos to Dave for an amazing job!

    the "HPN" has written Perth Darwin on the 43lt tank and the one with Paris Dakar on the standard tank is your bike you came to Daves work shop this morning, but we all understand you are drunk on emotions picking up your new baby after 18 months of anticipation with 75 hours labour.

    Its been a bit quiet on the update front, been busy.....riding :evil

    Took the HPM out today, so far its been all bitumen while we get used to each other, sort out any differences etc. You know that feeling you get when you ride a different bike for the first time?, it just feels different and it takes a while to get used to how it feels. Well the first ride on the HPM had a bit of that but no where near as much as I would have expected. It was really easy to ride and get a feel for. Apart from the very limited turning circle (only a problem in the garage) and very leaky front forks it rides beautifully. The front forks probably need a rebuild, I think they are the only component on the whole bike that hasn't already had that treatment. They probably need stiffer springs too for the extra weight, of the bike of course :lol3

    So having a few 100km under our belt today felt like a good day to introduce a bit of dirt. Take note all those who thought it would never see a dirt road!
    I planned an easy half day route through some nice country side that by memory would involve a relatively short gravel and sand section that I have ridden once before a few years back. My thinking is to take it easy and not just jump in for a full day on dirt especially knowing the front shocks still need work.

    Well when I arrived at the said sandy section I found it pretty chewed up, looks like the 4wd's and the Quads have been playing out that way (Warbrook Rd out the back of Gnangarra). The road surface varied considerably from relatively hard packed gravel to very chewed up soft sand with wheel ruts and whoops in between. I started a little cautiously not really knowing what to expect. My first impression was the bike is amazingly stable at low speed in these conditions. My R1200GSA tends to feel unstable under about 80km in this sort of dirt it likes a bit more speed. The HPM by contrast was very stable and manageable all the way through from start to 80 (told you I was going to take it easy day one). So off we went quickly becoming more comfortable and confident. I stopped to take some photos but my Iphone camera wouldn't work with gloved fingers and these gloves were a pain to get on an off, it was cooold this morning so I was wearing gloves that fit under sleeve and have a gauntlet that zip over as well. Was having too much fun to stop and undo them for a photo-sorry!

    When I came across the first deep sandy section I was thinking ok what feedback am I going to get, will the sand try and wrestle the bike off course will I need to wind on the power to keep things tidy. To my surprise it tracked perfectly, there was no wrestling with the bars no need to apply more than a modest bit of throttle. It tracked through with absolute stability and minimum of fuss. Hey I like!
    A few more sandy sections and the same results. The engine was effortless I left it in third most of the way and had no need to change gear the engine just pulled smoothly and felt really relaxed.

    Later through the bitumen twisty's it performed just as well purring along at 100km/h doing 3900rpm in 5th and just flowing through the bends. I'm really pleased so far, had a great morning out and everything felt good.
    Its running a lower 1st and higher 5th hear which I am really pleased with. In first I can let the clutch out and apply no throttle and the bike will chug along like a land rover at a fast walking pace even up a gentle slope with no sign of stalling or straining.

    Based on today's experience I am looking forward to taking the HPM on a longer dirt ride, it could do with slightly lower and rear set foot pegs so that standing on the pegs is more comfortable. I have already fitted 25mm risers and cant go higher without messing with the cables. Dave is going to investigate some new springs and seals for the forks which can be done when the bike goes back for its 1000km service.

    BJ's HPM (the white one in my earlier photo's) is now coming along quickly and should be on the road later this month. He has the additional 7.5L fuel tank mounted in place of a pillion seat, so it looks a little different, but good!
    I'll make an effort to get some pictures for the next post.
