    thanks for the offer but got no gear. Did skyline Bayview to CONZ then down Walters bluff this morning and back out to atawhai. Just a little unfit me thinks but a few more rounds of that loop should help.

    One thing I do want to do is set/check the sag on the EXC. The PDS rear is apparently fussy, needs to be much closer to ideal than linkage types.

    bloody wx. shrinking hot on last bike ride then today got drenched. made it all the way up Bayview to skyline and along the top with no walking. then we went up the maitai and the first third of the tantragee to find it closed due to fire risk.

    yesterday was up cable bay walkway with a 17kg pack (sleeping 3 year old). good work put but my old new alpine climbing boots trashed my feet (blisters on toes and heals). cycling seems to be ok though.

    pretty stoked with the efforts given done next to no exercise this year.

    real question, where be fun to mtb ride now? need a bit of a hill to get the heart pumping and the lungs heaving but not too technical cause ain't fit enough for that.

    Involution. Read about it here or google. Great track to practice sticking your inside leg forward into the turns. :evil Shame after the grind up that it's sub-20 mins to get down, but hey, that's Nelson all over. :lol3

    Codgers MTB Park is still open, izit? Sh!tloads of good riding in there.

    I went for a ride yesterday avo & thought I should have given you a call. This heat is extremely energy sapping:D

    Anything from Fireball rd over to the Maitai is OOBs at the mo.

    Go to Codgers up Brook St & ride up firball to the top trig on Sharlands hill & you have a magnificient downhill on some brilliant tracks. I couldn't really understand the map at the bottom & I know the tracks :huhbut I'm sure with your map skills you'll nail it.
    There are some maps floating around at the bike shops I think if you want to carry them but everyone is pretty helpful.

    Involution is a great track up Marsden Valley Rd but the ride up is punishing.
    Dun Mountain walkway is a fantastic ride - about an hour & halfish to Third house & then all downhill back - watch for walkers tho - heaps of tourists around.

    Fringe hill is another massive climb - since it's on the road noone really classes it as OOBs. About 1 1/2hrsish to the parking lot. From there you can either go down the Nat downhill track - only a couple of scary chutes yu can slide down or go down the sketchy Classic rd back to the brook.
    If you do intend to do the Downhill track it may pay just to post on KB your intentions & post up again when you get home.

    no treadly today. family day, rest day and gear dry out day.

    might be keen for another spin tomorrow. will see what bro in laws plans are and wx is like. codgers looks like a goer thought android phone doesn't like the pdf. will post mid tomorrow morning if I have any firm plans - firm plans and in-laws are two pairs of words that don't really go together;)

    Gah! Enough talk about treadlies, I went for a ride on a proper bike today! :lol3

    Shame about the rain/wind/fog/cold/wx in general. Since it'd been raining for a while, the Mackley was never going to happen, but I was prepared to go in and out from either side for a reccie/ride. However, Denniston was in the clouds and rather unpleasant so I didn't go any further than the museum.

    Serviced the shock linkage the other day. Man, it is so much simpler and easier when done in time as a service item rather than neglected and becoming a repair. Just unbolt everything, wipe out the old grease, smear in some new grease, bolt it all up again. Simple. Only took a few more minutes on top of removing the shock.

    Initial tests of the lighter shock spring are very positive. Might need a bit more preload, or valving to take more load - or, I just need to get used to a bit more compliance in the rear and it riding a bit lower. It follows the road a lot better and feels a lot less choppy. It's also more balanced front/rear which is always a good sign. The main aim of the exercise was to increase traction via better compliance. I think that's a win: on smooth gravel when you opened the throttle, the bike used to either spin up or snap sideways very suddenly. Now it takes a lot more throttle to get it to spin (it tends to find drive more), and it slides out in a comparatively gentle and controlled manner. Result!! :clap

    The Porika Track is very rough at the moment. The climb from Rotoroa is all football-sized boulders, criss-crossing ruts and sections of exposed clay. The tricky bit above the lookout is now the easiest part, and it looks like someone has been doing some road repairs there to smooth it out. The rest of it is in better condition than previously and it looks like it's had a bit of traffic with smoothed-out wheel tracks. Slippery as a greased pig in the rain still! I'd like to take the credit for getting up there without stopping or even dabbing, but I think the lighter shock spring helped quite a bit.

    And to top off the day, I made an oops with fuel. Instead of starting the day with 19L according to the trip meter, I must've reset the trip at some inappropriate time, because nearly halfway from Westport to Murchison, I ran on to reserve...when I was expecting about 10L remaining...WTF?! :eek1 Fortunately on reserve I can get more than halfway from Westport to Murchison :lol3 :clap although I was being very gentle with the throttle and cruising at 80-90 kays. Note to self: don't f*#&$^#%ing reset the odo unless the tank gets a full fill! and/or dremel a fuel visibility strip of paint off the tank.

    All up a good day's ride. Kohaihai, Kongahu Swamp Rd, Karamea Hwy, Denniston, Lower Buller Gorge, Upper Buller Gorge, Braeburn Track, Porika Track, Hope Saddle etc to home.

    I repaired the puncture from the last pushy ride/walk.
    It's had a slow leak for a month or so that I thought was the valve. A small section of the tyre was touching the frame rail so I had let the air out and rotated the tyre a few cm and pumped it back up. This was enough for the thorn to come out of its little hole apparently...

    Much nicer riding with air in the tyres...

    Anything organised yet ?
    I've been doing some research on the front wheel wobble at 140+km/h(on a closed road of course :D ) and it may be the suspension set up :deal
    Apparently it helps with cornering too. Who knew ? *facepalm*

    Short notice, but... tomorrow night, Weds 9th, feel free to come over to my place for bikes/bbq/booze etc.

    Shed time!

    Edit: and wrt to ztaJ's suspension, it might be an idea if we go out for a short ride with a good spread of terrain to do some suspension setup. This weekend some time? Although setting sag is #1 priority and should be done first.

    Tomorrow night sounds good.
    After much research and contemplation ( I chatted to woodman :D ) I raised the forks about 15 mm before going through Molesworth. It seems to have worked in eliminating the feeling of "pushing" the front in corners, much more stable at pace too.

    On the XR, there was a huge difference changing the forks by 3mm...

    It went from being ok for MX but too twitchy for anything else, to comfortable for a 3hr X/C.

    The twitchyness came with changing from a 23" to 21" front wheel and raising the back with some new shocks.
    It equalled raising the forks through the clamps by 50mm :evil

    Topical indeed.

    Weirdly the klrs handling has gone well pearshaped of late.

    Since replacing the trailwing to an mt21 and the smooth fullbore with a shinko 244, replacing the steering head bearings and putting the IAS rear shocky in,the bike is having serious front end issues. Sledging, very slow steering. I have played with raising the forks in the clamps with some success, but still not great. Problem is I am not sure which one of the things I have replaced is responsible. The rear shock is lovely which may mean I am riding faster and the front is just being more klrish than normal possibly?? maybe just the lack of riding time e.g. rider issues?

    Any thoughts, not sure yet if I can make the shed night.

    Raised or lowered? Raising the forks in the triple clamps will make the bike significantly less stable, as you are standing the bike on its nose by 15mm, steepening the rake.

    Changing the fork height by 5mm is considered a big change for a road bike. Therefore 15mm is atronomical, but tempered by the long travel suspension. My Triumph had a 2mm spacer inserted in the shock which increased the ride height at the axle approx 6mm... that made a massive difference to the handling of the bike.

    If you did actually raise the forks and it feels more stable, then it sounds like the extra front weight bias has made it feel planted. Which implies the rear is too low, making it feel like a chopper, or the handlebars are too far back. My 640A with the bars in the standard position felt like a chopper, with too much rearward weight bias. I run them rotated forward in the clamps at position 1 of about 2.5 available (ran 1.5 for a while but that was excessive). Pulls your torso forward to load up the front. You may be able to do similar. I also ran the original '90-'92 bars on the Triumph, which were lower than the '93-on ones. The bike was designed for the former. Again, this put more weight on the front wheel; with the higher bars it felt like a bus/barge with a huge disconnect to the front wheel.

    Checking the sag will tell you how the rear is sitting, versus the design of the bike - you'd expect the chassis to be basically correct once the springs are.

    The change could also be a confidence thing. A little more confidence and you are opening the throttle a lot more. Front-end-heavy bikes like the 640A need throttle to drive the bike through the corner, unweighting the front and rear wheel steering; works even with road-oriented tyres. Best thing you can do to make it steer is fit a fresh chunky rear tyre to get lots of driving bite. So you may be feeling confident enough to ride the bike more vigorously, helping it to handle.
