nice

TG

PS and dont use locking pliers instead of a proper nut in the final build

[scunny]

those vicegrips would be good for at least one season of racing.
is that a water buffalo wheel ?

 it's a Grimeca

[voxonda]

Had one on a bike of mine:


Still thinks it looks great. But make sure you got the right material on the shoes. I did not get along with them.

[turboguzzi]

well rob, those 230mm grimeca 4ls were original equipment on much smaller bikes, like morini 350-500 twins and duc singles, so would expect them to be undersized on a +200kg 750.... you must have cooked the poor thing...

guess that for a "show" 500 replica like paul is building it'll be OK.

[voxonda]

Stop right there.........................200+ 750?
Weighed the damn thing with oil and half a tank of gas, about 12 liter, the scale said 186 kgs. That is not that heavy, problem is the rider weighing 110 kgs.

Cheers, Rob

[turboguzzi]

well, didnt want to go personal.... but indeed, compared to a 150kg or less morini with a tiny italian rider.. so yes, a bit undersized for Rob's 750

Come on, TG... vice grips aren't appropriate hardware? 

As you can see in the picture, I use an old swingarm as a truing stand. The stock axle is too long, so I used the vice grips to set the axle to a point where the nut bites on the other end. to keep the hub in place, I use hose clamps on the axle. It's budget for sure, but it works.

Actually, TG, the 230mm 4LS Grimeca is identical to that fitted to the factory Benelli 650S Tornado, and that was not a small bike. My only gripe with the Grimeca is it's heavy unsprung weight. That's the only reason I sold my last one, other than that I was stone broke at the time!    RR

It is ridiculously heavy. I can't imagine ever using it for any other reason than creating a replica or racing a class that requires drum brakes and needing a decent option.

After all, it's a street aluminum drum brake (with speedometer take off.. )

proper racing drums are magnesium and cost like my whole bike....

can pick one up for you if you need, factory is not far from home

It's a darn shame they get all dirty, it's almost art

Menani : 8.4kg
Grimeca 4ls :  9.5kg

Not saying the grimeca is a better drum brake, though. I dunno.

the grimeca is 230mm, the menani 250mm.... AND lighter. Again, wouldn't be concerned if bike is built for parading/fun on track, 

more of an issue for guys running G50's, Manxes or Patons in Premier class, but if you have the money to race a 50K$ bike at the sharp end, then a 2K$ front brake is small change i guess.

On our CB500 we used first a replica Honda RC162 brake , weight 5 kg and 230 mm.
On some tracks we had fading despite the good brake liners we had.
A friend with the same brake on his racer has constantly problems , fading and overheating the brake , he tried many kinds of brake liners.
But he has not the money to buy a Fontana.
The Honda is under raceconditions to heavy for such a brake.
We changed during the season to a replica Fontana 250 mm which is 2 kg heavier.
The brake liner of the Fontana are longer and wider , so more brake surface.
Also the airflow trough the brake is much better.
Despite the heavier weight the braking of the Fontana is so much better than before , no more fading.
It feels like a good twin disc brake.

Back from the dead! What happened to this build? Started off strong, wandered on drum brakes and then the whole thing died.

That's pretty much what happens when people start to get all misty-eyed over $2700 4LS 250mm Fontana's. 

And people call me a "thread killer"... 

 

[paulages]

It's still in progress... boring stages. Sourcing parts, engine building, etc. There'll be pics eventually! The Grimeca 4LS front is already built. Beautiful! (and heavy...)

[fastbroshi]

Reminds me of hot rods with flatheads.  They don't have near the power potential of anything built after 1960, parts are expensive, but they're so cool looking.

Hey Paulages, what are you doing for the back wheel? Reason I ask is it looks like I have a brand new rear rim, rear RC181 replica hub and stainless waisted spokes for sale and it's beautiful! :-)

I'll get some pictures...

[Bluegreen]

Looking forward to updates !!

I have the rear already laced up to the stock hub, but I'll pass the info along to my customer. PM me the price?
