Looked quicker than some of the other characters. Some serious tackle not being ridden there Very Happy

Never understood the SBK or MotoGP technique of stop, turn, point and squirt. Riding Guzzi's for so long with the only way to corner was to set up from a long way out and use sweeping lines.
Take a packed lunch while you waited for it to turn. I don't suggest I now have an RC211V or M1, but Bella now goes so deep into corners before bothering to turn, then just changes direction so quick and easy, with such precision. Getting on the gas so much sooner and just firing it out of the corner, I now have some perception of what they are talking about.

Pete, better bring the Blue Whale to Qld so I can see what all this GRiSO fuss is about, meanwhile .......................... take Bella for a long flog.

Thanks for sharing Wayne.  I think the vid shows the flavour of last Saturday very well but the road surface roughness is hard to capture.  Bella sounded very sweet followed closely by the little NSR. I  spoke with the NSR rider at registration and he told me he had never seen the road before - reckon the poor bastard must have been bucked around quite a bit.  

Even noticed a bit of vision of the V7 at Rathdowney.  I rode in a group much later in the day when there were more spectators on the lower part of the course, and after the two minor 'offs'.  I had plans for riding the G on Sunday, but that was not to be.  Plenty of time now to practice for next year.  But what to do about those wallopers north of the border??

Ah, was yours the black or green V7 with the Conti replicas?
Best part of the ride was following the 2-stroke for awhile. Sounds and smells good.

I've spent a lot of time trying to dial in Bella's suspenders for roads like that, especially corrugated apexes. Now I can accelerate over them instead of skipping sideways.

The matt black stone belongs my wife. It's dead stock but due for some after-market suspenders and a Dart flyscreen. The way you describe Bella handling rough roads with corrugated apexes is just how I had my Shiver set up with Matris cartridges and rear shock. The Shiver was perfect for roads like the Lions, alas I sold it off in June to finance my GRiSO. My G with stock suspension is just adequate but needs work be truly fun on the Lions. Unfortunately, i won't be able fund serious suspension improvements for some time.Sad

I have a spare GRiSO shock with a choice of springs and re-valved.
Surplus to my needs now, yours for $100 - good interim until you can afford a real shock.

Meanwhile, I swapped bikes with a mate today, and rode his Chris Pheiffer F800 Beemer round Beechmont loop.
Bella is definitely the lighter steerer of the two.

Hi, ghezzi, and others my first post here Very Happy

I have not a GRiSO Sad  but a pair of BST`s on my Berg so we do have something in common.

They are the 7 spoke SM version and have been on for about 4 years now.

I am particularly interested in this changing of drive hub as the SM 7 spokers do not
have a cush drive, and I am more than a bit worried that something, either gearbox
or crankshaft will eventually fail due to excessive shock being transmitted through
the chain drive...
I tried talking to BST about it a few years ago but got the impression they were not
interested in helping for the obvious reasons.

I am quite excited to see ghezzi has been brave enough to tackle the hub removal
process Cool

ghezzi, now you have removed that cush drive unit I was wondering if you would
part with it as I have a need of one such unit Smile  " if " the offset for the sprocket is correct
of coarse or close enough to be adjusted.  PM me if you think we can do a deal Cool
Will help reduce the overall cost of your project...  slightly Smile

I am happy to remove the hub as my trade is in toolmaking and understand most of the
process you have explained,  except perhaps the braking of the bond part scratch  was thinking of knocking out the bearing and
milling the complete hub away Shocked

ghezzi you have my sympathies as  I also suffer from the dreaded compulsive modification disorder and have been diagnosed as chronic Embarassed

Bella goes into hospital next week for a pre- plastic steel surgery check up.
Niccom engineering will look at cut-n-shut of the chromed V7 tank tunnel.
An unmodified tank can be made to fit if I remove the stock air box and fit pod filters, however I have been led to believe that EFI functions better with a still air box, so I will go the other way.

Good plan. I'm sure it could be made to work with pods, but there is the intake air temp sensor to consider, so an air box is always a good idea IMO.

Just filled the shrunken V7 tank, 17.25 litres which gives me a range of 300-340km.

Photos to follow one day soon, time to ride ..................... between the showers.

Oh no, that would really draw some odd looks. Rolling Eyes  But hey, aren't you supposed to be out test riding between showers?

As promised a photo of Bella in new clothes, in her natural habitat. Thank you Mr Roper.

Just did the border loop, Mt Lindsey and The Lions Rd, went past Gil's place (plantboy) but he wasn't home. Total trip was 286km, reserve light came on at 190km, av. 5.1L/100k. I should still have 2.75 litres left.

The reserve light sender unit is basically a brass rod attached to what looks like an old points condenser. Might see if I can lower it an inch, as a 10litre main tank and 7 litre reserve is a gross imbalance.

Ooooh my eyes! Hope you aren't distracted by the glare or from checking your reflection in that tank. Laughing  But I do love the look and the shape of it - really works with the rest of the bike imo.  Apart from the chrome, do you like it? 

My experience with the V7 fuel reserve is similar, with the light coming on far too early,.  Sorry I missed you but I was out doing a 200 km loop through Lismore, Mullum, Nimbin etc on jan's V7 Stone.  A lot of bikes on the road and even spied a Hwy Patrol Commode on the Kyogle Rd.

I can't see the tank when riding due to the chin piece of my full face helmet, have to check for reflection sunburn under my gills. Hoping to buy a Schubert flip front soon, could be interesting.

Taking photos is a challenge to avoid your own distorted reflection. "Does my arse really look that big"?
