Harsh Cer Forks.

So you obviously know about the dot that indicates where the valve aligns (to aid balancing), Jim?

Yes ....... and don't trust it to be the best spot to allow the best balancing.  I have had a couple of tires that balanced better with the dot 180 degrees out. I have also checked the balance of the bare rim and found some to be perfect and some quite unbalanced ......... most likely a spoked wheel in the latter case.
 
John took me on, almost unquestionably, Australia?s roughest sealed road. Proved two things, my front forks are way too harsh a, are the rear shocks.

Great on the track, and even the two front wheel lockup?s didn?t unsettle it too much.

So, I?m going lighter fork oil for a start and see what happens then.

Lighter than what w ?
 
Stick with the 10w and stick on the goat tracks....remove the falsies and pin it  ;) only place coppers don't hang out  8)

Makes ya feel alive a little bit of front brake lock up and jarring thru the bones  :D
 
Chris, does your fork have clickers. What helps a lot with the rear shocks is pulling the bump stops down and seeing what the sag is and how much travel you are using. Without knowing this its imposable to adjust the shock settings, it could be soft and bottoming or so hard it's not moving much. Same with the forks, cable tie time.
 
After politely wanting 3 and a half days for the fork springs to come from across Sydney I gave them a ring only to find they had forgotten to send them. Fuck me.
 
I love my Laverda, on it, you can remove and replace the rear wheel while leaving the chain untouched. Its hard to believe but I had to break the chain on the Pantah to refit the wheel now with a slightly bigger rear sprocket, bloody stupid design. Bloody chain lube is like tar, Andy was right, the less lube the better.
 
Now Now Vince..... nothin wrong with a bit of chainlube now n then  ;) after a ride and wipe off excess.

If yours has turned to tar.... maybe ya need to clean it more often (rag soaked in Inox/wd40)

Give it some lovin and it will pay ya back in spades  ;)
 
I finally received the lighter fork springs, before 0.95 and now 0.8. With the same, tiny amount of preload, I now have 100mm of travel with 40mm of sag. That's with a brand new tyre, zero ks, so I wasn't pushing it. Its much better, but I need to get beyond my block and at higher speeds. It needs a bit more preload to get to a better 30mm sag figure. I am very glad I didnt go to 0.85 spring, thanks for the calcs, Cam. Cam calculated there would only be a 5mm difference in travel between the 0.8 and 0.85 springs, that's theoretical as real-world stuff has an effect.
The gearing change looks very good as well.
 
In theory, reality and theory are the same but in reality they are different.  ::)

I hope they're not too soft that you start wallowing around... :o :o :D
 
Me too, but from that short test its still far from wallowing. I am adding 5mm of washers to see if I can get closer to 30mm of sag
 
Butterfly effect, tiny random inputs that result in big unexpected changes. And that's 90% of the fun playing with this. Do something that's taken as gospel and see for yourself. And that's my biggest lesson with this, you're going to need 0.95 springs as your a big boy and that's what works for the GSXRs and stuff I normally do. O your only getting 80mm of travel, start coming up with lots of expensive fixes. No, lest not try softer springs as that's imposable to be the fix. Its a 5 minutes experiment, NO that cannot be it. Have you tried other springs on other old bikes, NO but that cannot be it. It's not been that expensive, $180 for the second set of springs, $120 for the hard anodising, $300 for the expert to pull them down for the second time and find and do nothing, that pissed me off. And $100 for assorted oil and stuff plus hours of fun. It least I finally got somewhere,thankfully

Or reality!  ???

Could be a glitch in the matrix.
 
Here is the latest glitch, I am doing a gearing change so while I am at it a new chain seemed smart. Off I go across Sydney to the National Distributor, well no we dont have any here. So its coming from Melbourne, chain arrives and I attempt top fit it. No removable chain clip, only a rivotable one and I am not keen. Luckily I bought 2 removable clips for the Laverda while I was there, but there also 530 but a grade stronger and don't fit. So I ring them and it seems I was sent an X ring chain and not an O ring, nobody have any removable clips but he can send me an O ring chain with a removable clip from Melbourne for free as its there stuff up but I won't get it till Monday. How does anybody make any money these days?
