Poor running

The real way forward here is to get original Jota 120 inlet manifolds and RGS type carbs, they then conect to each other with a simple hose and jubilee clips, the factory hose is stepped,or ridged internally, but I would'nt think that is vital.

This is going to come up more and more because if you "wiggle" the 180 type carbs away from the alloy manifold you will very likely crack the mounting socket on the carb, its is very common, some bikes even have the cracks and still run (badly) without the owners even being aware.It is also relevant to the RGS series, since the bolt on rubber inlet manifolds are now getting to be in short supply and they perish, so the same reasons for a change apply.

I suppose a lot will by pass this and just go for a Mikuni conversion, me? I am still dreaming of useing a single 45mm carb on TOG, a car type SU was atractive at one time, due to the auto richening of the mixture as fuel temperature in the float bowl rises, very handy if stuck in Milan at 1729hrs, but now I am perhaps leaning to a carb from  honda SP1, which is a little bigger 48mm I think.

Is it possible for the bike to run acceptably without these insulators?

Yes. I bought the manifolds and only had them machined to fit the plastic insulators inside the Dellorto carbs. I left them longer than the old ones, and "deleted" the insulators attached to the cylinder heads and one set of 'O' rings to get the carb spacing right. I already had a set of thicker O rings so the deeper groove on the manifolds were not a problem.

I've got a bag full of the O rings if anyone wants some - they're the correct rubber n stuff. I bought a total of 50 I think (in a few different thicknesses) for about a 5er after looking at the prices for the OEM kit and falling over.
 
wake up Toddy,
see post 16
and pay attention in future or you will have to go and stand in the corner

Hello,

I've bought this o rings http://www.motalia.net/product_info.php?products_id=1775
I read here on forum, that the viton rings are apropriate.  Do you think, that this, wich I bought are viton, or should I buy new(viton) ones?


Thanks

Clem the RGS inlet manifolds are readily available from Wolfgang (cheapest) Wagner and after I tipped Richard off at Slaters too .I have a lovely new set from Wolfgang.

sure thing Shaun, 100% in fact, but just like the clutch cush drive rubbers they no longer last 25 years more like 25 months, well more like 18 actually, but 25 sounded better

Baldy john and Jim B have just managed to get some Chott drive chain rubbers from a UK supplier of Ariete rubber stuff, after several attempts by me to order some, several attempts by other UK Ariete dealers (prompted by me and john) to order some and eventually successfull, via Jim and a contact shop (I believe) in Weston super Mare.I hope they last at least half what the originals do.
 
If you think it will fit, PM me - I have one original spare (only 2 were broken, but I have bought 3 new matching alloy ones)

Does the inlet stubs from Elegog fit the 500 head? One of my inlet stub is broken and need new one(s) but I doubt the original are available, or...?

Arne,

500 inlet stubs are the same as early triples.  Billet replicas available from OCT,  octeam@gmx.de

New inlet stubs and insulators, cams out and valve clearences sorted and all back together. It's a different bike - runs very well. Just needs the cabs tuned a little. What a joy to hear and to ride today.

Thanks for all the tips from this forum
