Re: Oil in telescopes - oil in gearbox

I forgot to ask about how much oil there goes to the front teles? How much oil to use in the gearbox?? (Hopefully given in cc or millilitres...) Unfortunately - I havent got a "users handbook" - is it possible, that such booklet had exsisted (for RUMI motorcycles) in the past... If anyone have a cop...

Re: Oil in telescopes - oil in gearbox

Thank you Eddie! The SAE 20 - is it dedicated Fork Oil - or just "oil"? (You know anti-foam - anti oxygen, and all that stuff...) My front tele is somewhat "stiff" or hard - when I pulled everything apart. it looked OK - quite unworn - but i suspect thet the springs might be unoriginal - meant fro c...

NGK Spark Plugs for a "Hot Rumi Bicarburatore"?

Sorry - its me again... On my newly accquired "Bicarburatore" I found NGK BP 4 eS spark plugs They must have been installed for a reason? But why just 4?? I am normally using NGKs BP 6eS or BP 7eS in two-strokes. I like to stay with NGK - so please - if anyone have experience with the "Hot" Rumi mot...

Oil in telescopes - oil in gearbox

Yes, thats me again... Now I am working on my 1954 RUMI front tele (the type with hydraulic damping) - as I dont have a RUMI manual, I ask if someone "out there" should know - or have experience with, what type of oil such an old construction will work best with? On my other bikes I use "BelRay" 10W...

Re: Ignition Firing point before tdc?

Thank you for supplying me with your opinion about "firing point" bdtc. 28 degrees are in my calculation 2,77 mm before tdc... Isnt that too much? Modern fuel burn hotter and quicker - so I could be in danger with so advanced a firing point. I will start with the "factory settings" of 2 mm - or even...

Re: Oil quality for "Hot" RUMIs - and some other topics...

Thank you so much! I am very glad to hear from a real expert. You are absolutely right - this engine has been tuned (tampered with) 30 years or more ago - but (by then) a two-stroke expert. So its not too bleak - just difficult, to figure out what these ancient racers had in mind? You are probably r...

Re: Ignition Firing point before tdc?

Thank you for this reply! Yes, since many years I had a "spark plug probe" I also has access to a motorcycle "rolling road" - to fight blind carburation spots and so on - and to etablish the densities of gas, at full throttle. The "pinking noise" I found the reason for yesterday: By changing a 2 mm ...

Oil quality for "Hot" RUMIs - and some other topics...

Oil quality for "hot" RUMIs - sparkplugs for same - remote float-chamber fluid level?? I wonder if any members "out there" might know about which two-stroke oil to use in iron cylinders? Which percentage is "safe" to use - 5%? - should it be fully synthetic? or maybe a blend with a tiny percentage o...

Re: Ignition Firing point before tdc?

How I measured it? Why I measured it? First i put one piston in exactly top position - (luckily, corresponding with the marking at my "Nassetti" flywheel) Then I carefully turned "backwards" and forwards, in order to feel exactly WHEN the contact opened (by way of "cellophane" - and a little later, ...

Because I have a complete RUMI 1954 ignition system, with new (double) coils - new points, and a very nice CNC made back plate, with room for the two (new) capacitors I also have.

Nah - I am not that ashamed! I have several "Veglia" speedos - and bending the "Italian" flaps I have done a number of times - with succes... I have been driving my single cyl. Moto Guzzi for 10 years - totally without water ingress. (By the way - I have a perfect working "Veglia" square speedometer...

Re: Kit restoration for speedometer, How to assemble?

Hi HoH - very easy! You just (very carefully) un-bend the small metal "flaps" of the speedo housing. Then place a gasket - then the (plastic) "glass" - maybe another gasket (if space allows) - i never use more than one... Finally - re-bend the metal"flaps" - and pronto - its done! If you fail? - if ...

Re: New fully generator/electronic ignition from Powerdynamo

Hi there Hugo, yes I have used one on a Junior Gentleman and it works fine. The only problem was where to put the batteries, easy on a scooter, but on the bike I had to put them on the underside of the saddle. p.s. I used 'Cyclon' batteries.....no acid!
