Re: What did you do to or for or with your Laverda today?

Buttoned up primary side on the SF2. New primary chain from Andy, new tensionner.
Didn't put points plate on. Will do that when I've nearly finished.
Thought I'd put oil in it. Motul 300 V which I can obtain quite cheaply. Put around 3 litres in and left garage for 10 mn. Came back to find a large puddle of nice clean oil on the floor. I'd forgoten to put back the small triangular selector cover on.
I'll clean up tomorrow.

Boozed up, fuelled up, sunscreen on and he's off............

By the way, in case you can't tell from the pics this is one beautiful bike.

Great looking bike Andy.
 
Been shaving the inside of my callipers this morning ......... FFS, how many BIC razors can a bloke go through!

I've now got 2.5mm clearance to the spokes from the inside of the callipers. Does anyone know how much flex a spoked wheel gets when cranked over?

Found 6 broken spokes on my rear rim last year after a run over Reefton Spur. Hate to think how much flexing was going on then  :o

6 in a row, or throughout the wheel? Maybe you picked up a stick.

Re: Flex. I suppose if I crank it over and the spokes touch, I'll know about it. May have to Google this subject.
 
I don't have an answer to how much a spoked wheel will flex. It's dependent on a lot of variables like spoke tension, wheel geometry, etc. but I wouldn't have thought it would be anywhere near 2.5mm. With that kind of deflection the spokes wouldn't last very long before faigue failures start to happen.

The other thing to consider is flex in the caliper mountings or twisting of the forks when the brakes are applied. But again, I reckon 2.5m would be getting into the structural failure range.

So my guess is that 2.5mm is more than enough clearance. Take it for a ride, stop and check whether there's been any contact. There will be some paint missing from the caliper if there has. If not, try upping the pace and lean angles.

The lateral forces on motorcycle wheels are not very severe during normal riding and cornering. The the ultimate test would be to get it into a viloent tank-slapper  ;)
 
BTW, it's hotter here today than yesterday. 35?C outside, but the temperature inside the tin shed that houses my garage/workshop has gone beyond sauna and is now in oven territory, so no chance of me doing anything in there today. Although I suppose I could try roasting a chook on the workbench.
 
Chris this is a bit controversial,less so in the USA off road scene but I have bought a Spoke Toque Wrench to get my spokes to an even toque.Motion Pro sells them.Seems to keep wheel rims in line for longer in  MX racing.You need the nipals to be in good nic,no corrosion to change the  friction.Having spokes deflect to any degree would have the rim moving about having a huge effect on handling,you would notice that for sure.

Was in pairs, at three fairly equal arcs around the rim.
 
Keep an eye on the rear spokes Pat if you look carefully at the hub you will see a contact point on the outer flanges where in the fact the spokes will have quite a point load and look like they are bending off the flange.
 
That's about the area where they failed Maurice. As you know, all is well again  8)
(Was front rim actually that was popping spokes, but had both rebuilt)

(well......starter motor is another story!)

Washed the 3C so had to take it for a ride  :o

Then when I came back to the RGS for a ride to try out the new front tyre... thanks Levo the Pilot Activ seems not too bad and now more steering shimmy or vibration.

Apart from the feedback on the performance I asked you about any chance you could post or even send me a clip of it running so I could hear them too Paul? If possible thanks in  advance.  :D

Will do.
I haven't forgotten but it'll be another month yet I imagine.

Got my Jota from its crate just arrived from South Africa, put the front wheel on, checked fluid levels, all good. Added a hint of petrol, reconnected the battery and touched the starter button,no firing, a bit of choke. Oh must open petcocks, d'oh! Then the most wonderful sound filled my garage and most of east Bungendore.  Given that I crated it in November 2014 I was really impressed with the Motobatt and it idled happily at 1,000 rpm, all this after a three month sea voyage and warehouse in Sydney while the quarantine and customs types did their job. What great bikes they are!

Cheers

Since the weather was above freezing I went for a nice run for an hour or so.
She took a few turns to get going as there hasn't been much action for a month, but mucho funno!!
Still runs pretty much perfectly.

Looking forward to spring!
